How to change date format in Excel and create custom formatting

The first part of our tutorial focuses of formatting dates in Excel and explains how to set the default date and time formats, how to change date format in Excel, how to create custom date formatting, and convert your dates to another locale.

Along with numbers, dates and times are the most common data types people use in Excel. However, they may be quite confusing to work with, firstly, because the same date can be displayed in Excel in a variety of ways, and secondly, because Excel always internally stores dates in the same format regardless of how you have formatted a date in a given cell.

Knowing the Excel date formats a little in depth can help you save a ton of your time. And this is exactly the aim of our comprehensive tutorial to working with dates in Excel. In the first part, we will be focusing on the following features:

Excel date format

Before you can take advantage of powerful Excel date features, you have to understand how Microsoft Excel stores dates and times, because this is the main source of confusion. While you would expect Excel to remember the day, month and the year for a date, that's not how it works...

Excel stores dates as sequential numbers and it is only a cell's formatting that causes a number to be displayed as a date, time, or date and time.

Dates in Excel

All dates are stored as integers representing the number of days since January 1, 1900, which is stored as number 1, to December 31, 9999 stored as 2958465.

In this system:

  • 2 is 2-Jan-1900
  • 3 is 3-Jan-1900
  • 42005 is 1-Jan-2015 (because it is 42,005 days after January 1, 1900)

Time in Excel

Times are stored in Excel as decimals, between .0 and .99999, that represent a proportion of the day where .0 is 00:00:00 and .99999 is 23:59:59.

For example:

  • 0.25 is 06:00 AM
  • 0.5 is 12:00 PM
  • 0.541655093 is 12:59:59 PM

Dates & Times in Excel

Excel stores dates and times as decimal numbers comprised of an integer representing the date and a decimal portion representing the time.

For example:

  • 1.25 is January 1, 1900 6:00 AM
  • 42005.5 is January 1, 2015 12:00 PM

How to convert date to number in Excel

If you want to know what serial number represents a certain date or time displayed in a cell, you can do this in two ways.

1. Format Cells dialog

Select the cell with a date in Excel, press Ctrl+1 to open the Format Cells window and switch to the General tab.

If you just want to know the serial number behind the date, without actually converting date to number, write down the number you see under Sample and click Cancel to close the window. If you want to replace the date with the number in a cell, click OK.
Use the Format Cells dialog to get the number behind a given date in Excel.

2. Excel DATEVALUE and TIMEVALUE functions

Use the DATEVALUE() function to convert an Excel date to a serial number, for example =DATEVALUE("1/1/2015").

Use the TIMEVALUE() function to get the decimal number representing the time, for example =TIMEVALUE("6:30 AM").

To know both, date and time, concatenate these two functions in the following way:

=DATEVALUE("1/1/2015") & TIMEVALUE("6:00 AM")

Use the DATEVALUE and TIMEVALUE functions to find the number behind a given date and time in Excel.

Note. Since Excel's serial numbers begins on January 1, 1900 and negative numbers aren't recognized, dates prior to the year 1900 are not supported in Excel.

If you enter such a date in a sheet, say 12/31/1899, it will be a text value rather than a date, meaning that you cannot perform usual date arithmetic on early dates. To make sure, you can type the formula =DATEVALUE("12/31/1899") in some cell, and you will get an anticipated result - the #VALUE! error.

If you are dealing with date and time values and you'd like to convert time to decimal number, please check out the formulas described in this tutorial: How to convert time to decimal number in Excel.

Default date format in Excel

When you work with dates in Excel, the short and long date formats are retrieved from your Windows Regional settings. These default formats are marked with an asterisk (*) in the Format Cell dialog window:
Default date formats in Excel

The default date and time formats in the Format Cell box change as soon as you change the date and time settings in Control Panel, which leads us right to the next section.

How to change the default date and time formats in Excel

If you want to set a different default date and/or time formats on your computer, for example change the USA date format to the UK style, go to Control panel and click Region and Language. If in your Control panel opens in Category view, then click Clock, Language, and Region > Region and Language > Change the date, time, or number format.

On the Formats tab, choose the region under Format, and then set the date and time formatting by clicking on an arrow next to the format you want to change and selecting the desired one from the drop-down list:
Setting the default date and time formats in Control panel

Tip. If you are not sure what different codes (such as mmm, ddd, yyy) mean, click the "What does the notation mean" link under the Date and time formats section, or check the Custom Excel date formats in this tutorial.

If you are not happy with any time and date format available on the Formats tab, click the Additional settings button in the lower right-hand side of the Region and Language dialog window. This will open the Customize dialog, where you switch to the Date tab and enter a custom short or/and long date format in the corresponding box.
Setting the custom date and time formats

How to quickly apply default date and time formatting in Excel

Microsoft Excel has two default formats for dates and time - short and long, as explained in default Excel date format.

To quickly change date format in Excel to the default formatting, do the following:

  • Select the dates you want to format.
  • On the Home tab, in the Number group, click the little arrow next to the Number Format box, and select the desired format - short date, long date or time.

Quickly applying the default date and time formatting in Excel

If you want more date formatting options, either select More Number Formats from the drop-down list or click the Dialog Box Launcher next to Number. This will open a familiar Format Cells dialog and you can change date format there.

Click the Dialog Box Launcher to open the Format Cells dialog.

Tip. If you want to quickly set date format in Excel to dd-mmm-yy, press Ctrl+Shift+#. Just keep in mind that this shortcut always applies the dd-mmm-yy format, like 01-Jan-15, regardless of your Windows Region settings.

How to change date format in Excel

In Microsoft Excel, dates can be displayed in a variety of ways. When it comes to changing date format of a given cell or range of cells, the easiest way is to open the Format Cells dialog and choose one of the predefined formats.

  1. Select the dates whose format your want to change, or empty cells where you want to insert dates.
  2. Press Ctrl+1 to open the Format Cells dialog. Alternatively, you can right click the selected cells and choose Format Cells… from the context menu.
  3. In the Format Cells window, switch to the Number tab, and select Date in the Category list.
  4. Under Type, pick a desired date format. Once you do this, the Sample box will display the format preview with the first date in your selected data.
    Changing the date format in Excel
  5. If you are happy for the preview, click the OK button to save the format change and close the window.

If the date format is not changing in your Excel sheet, most likely your dates are formatted as text and you have to convert them to the date format first.

How to convert date format to another locale

Once you've got a file full of foreign dates and you would most likely want to change them to the date format used in your part of the world. Let's say, you want to convert an American date format (month/day/year) to a European style format (day/month/year).

The easiest way to change date format in Excel based on how another language displays dates is as follows:

  • Select the column of dates you want to convert to another locale.
  • Press Ctrl+1 to open the Format Cells
  • Select the language you want under Locale (location) and click OK to save the change.

Converting Excel dates to another locale

If you want the dates to be displayed in another language, then you will have to create a custom date format with a locale code.

Creating a custom date format in Excel

If none of the predefined Excel date formats is suitable for you, you are free to create your own.

  1. In an Excel sheet, select the cells you want to format.
  2. Press Ctrl+1 to open the Format Cells dialog.
  3. On the Number tab, select Custom from the Category list and type the date format you want in the Type box.
  4. Click OK to save the changes.

Creating a custom date format in Excel

Tip. The easiest way to set a custom date format in Excel is to start from an existing format close to what you want. To do this, click Date in the Category list first, and select one of existing formats under Type. After that click Custom and make changes to the format displayed in the Type box.

When setting up a custom date format in Excel, you can use the following codes.

Code Description Example (January 1, 2005)
m Month number without a leading zero 1
mm Month number with a leading zero 01
mmm Month name, short form Jan
mmmm Month name, full form January
mmmmm Month as the first letter J (stands for January, June and July)
d Day number without a leading zero 1
dd Day number with a leading zero 01
ddd Day of the week, short form Mon
dddd Day of the week, full form Monday
yy Year (last 2 digits) 05
yyyy Year (4 digits) 2005

When setting up a custom time format in Excel, you can use the following codes.

Code Description Displays as
h Hours without a leading zero 0-23
hh Hours with a leading zero 00-23
m Minutes without a leading zero 0-59
mm Minutes with a leading zero 00-59
s Seconds without a leading zero 0-59
ss Seconds with a leading zero 00-59
AM/PM Periods of the day
(if omitted, 24-hour time format is used)
AM or PM
Note. If you're setting up a custom format that includes date and time values and you use "m" immediately after "hh" or "h" or immediately before "ss" or "s", Microsoft Excel will display minutes instead of the month.

When creating a custom date format in Excel, you can use a comma (,) dash (-), slash (/), colon (:) and other characters.

For example, the same date and time, say January 13, 2015 13:03, can be displayed in a various ways:

Format Displays as
dd-mmm-yy 13-Jan-15
mm/dd/yyyy 01/13/2015
m/dd/yy 1/13/15
dddd, m/d/yy h:mm AM/PM Tuesday, 1/13/15 1:03 PM
ddd, mmmm dd, yyyy hh:mm:ss Tue, January 13, 2015 13:03:00

How to create a custom Excel date format for another locale

If you want to display dates in another language, you have to create a custom format and prefix a date with a corresponding locale code. The locale code should be enclosed in [square brackets] and preceded with the dollar sign ($) and a dash (-). Here are a few examples:

  • [$-409] - English, Untitled States
  • [$-1009] - English, Canada
  • [$-407] - German, Germany
  • [$-807] - German, Switzerland
  • [$-804] - Bengali, India
  • [$-804] - Chinese, China
  • [$-404] - Chinese, Taiwan

You can find the full list of locale codes on this blog.

For example, this is how you set up a custom Excel date format for the Chinese locale in the year-month-day (day of the week) time format:
Creating a custom Excel date format for the Chinese locale

The following image shows a few examples of the same date formatted with different locale codes in the way traditional for the corresponding languages:
Custom date formats for different locales

Excel date format not working - fixes and solutions

Usually, Microsoft Excel understands dates very well and you are unlikely to hit any roadblock when working with them. If you happen to have an Excel date format problem, please check out the following troubleshooting tips.

A cell is not wide enough to fit an entire date

If you see a number of pound signs (#####) instead of dates in your Excel worksheet, most likely your cells are not wide enough to fit the whole dates.

Solution. Double-click the right border of the column to resize it to auto fit the dates. Alternatively, you can drag the right border to set the column width you want.

Negative numbers are formatted as dates

In all modern versions of Excel 2013, 2010 and 2007, hash marks (#####) are also displayed when a cell formatted as a date or time contains a negative value. Usually it's a result returned by some formula, but it may also happen when you type a negative value into a cell and then format that cell as a date.

If you want to display negative numbers as negative dates, two options are available to you:

Solution 1. Switch to the 1904 date system.

Go to File > Options > Advanced, scroll down to the When calculating this workbook section, select the Use 1904 date system check box, and click OK.
Switching to the 1904 date system

In this system, 0 is 1-Jan-1904; 1 is 2-Jan-1904; and -1 is displayed as a negative date -2-Jan-1904.
Negative numbers are displayed as negative dates

Of course, such representation is very unusual and takes time to get used to, but this is the right way to go if you want to perform calculations with early dates.

Solution 2. Use the Excel TEXT function.

Another possible way to display negative numbers as negative dates in Excel is using the TEXT function. For example, if you are subtracting C1 from B1 and a value in C1 is greater than in B1, you can use the following formula to output the result in the date format:

=TEXT(ABS(B1-C1),"-d-mmm-yyyy")
Use the Excel TEXT function to display negative numbers as dates.

You may want to change the cell alignment to right justified, and naturally, you can use any other custom date formats in the TEXT formula.

Note. Unlike the previous solution, the TEXT function returns a text value, that is why you won't be able to use the result in other calculations.

Dates are imported to Excel as text values

When you are importing data to Excel from a .csv file or some other external database, dates are often imported as text values. They may look like normal dates to you, but Excel perceives them as text and treats accordingly.

Solution. You can convert "text dates" to the date format using Excel's DATEVALUE function or Text to Columns feature. Please see the following article for full details: How to convert text to date in Excel.

This is how you format dates in Excel. In the next part of our guide, we will discuss various ways of how you can insert dates and times in your Excel worksheets. Thank you for reading and see you next week!

      Please go to Format Cells, choose Number -> Custom Format and set
      mm-yyyy
      Or instead of the date in the cell, you can write text and not use custom format:

      =TEXT(DATE(LEFT(A13,4),MID(A13,5,2),1),"mm-yyyy")

      I hope it’ll be helpful.

        Hi,
        Thank you for getting back to me. The problem is that the the website generating the data gas a glitch and is presenting the day and month in reverse. So if it was the 13 May 2020, the cell contains 5/13/2020 but yet the excel sheet thinks it is the 5 of the 13th month which obviously causes problems. They are working ona fix to the site now but i would like to know if there is anything i could do to convert it in the meantime in case they cannot fix the issue.
        Hope to hear from you soon,

        Hi Alexander,
        I have the same issue as Anne, and change the format using the custom format option.

        However, I was wondering if there was any way to make the change as permanent, as every time I open an excel file, I have to change it, and this happens several times a day, so it gets a bit frustrating at times.

        Thanks in advance for your help

        • Hello Tabish!
          When you enter a date or time in a cell, it displays in the default date and time format. This default format is based on the regional date and time settings specified in the Windows Control Panel and changes when you configure these settings in the Control Panel. Set the format there. I hope it’ll be helpful.

      For me to be able to help you better, please describe your task in more detail. Please let me know in more detail what you were trying to find, what formula you used and what problem or error occurred. It’ll help me understand it better and find a solution for you. Thank you.

  9. Mel says:

    Hi how can I change a field value from "Aug 10 1984 12:00AM" to
    "1984/08/10"(yyyy/mm/dd)
    Normal format "date" is not working

    • Hello Mel!
      Your value "Aug 10 1984 12:00AM" is the text. Therefore, turning it into a date can only be done using a formula.

      =DATEVALUE(SUBSTITUTE(MID(T1,5,3)&REPLACE(LEFT(T1,11),5,3,"")," ","/")) + TIMEVALUE(RIGHT(SUBSTITUTE(T1,"AM"," AM"),8))

      Please go to Format Cells, choose Number -> Custom Format and set desired format

  10. Dave says:

    Is there a 'switch' for date formats to force uppercase text?
    I am trying to display 'April 2020' (mmmm yyyy) as 'APRIL 2020' without the use of =upper() function as the date needs to be displayed this way in the same cell as it is entered.

  15. Tony O'Brien says:

    Hi
    I have a date issue where by in a cell with text & long date & need to convert into short date by MONTH/DAY/YEAR? This is a two formula process. BELOW IS THE TWO FORMULA'S
    1 = Randwick Saturday, 06 June 2020 =MID(Z6,MIN(IFERROR(MIN(FIND({0,1,2,3,4,5,6,7,8,9},Z6&"0123456789",1)),LEN(Z6)+1)),LOOKUP(1,0*MID(Z6,ROW(INDIRECT("1:"&LEN(Z6))),1),ROW(INDIRECT("1:"&LEN(Z6))))+1)

    Returns = 06 June 2020

    2 =DATE(RIGHT(Z1,4),RIGHT(LEFT(Z1,2),2),LEFT(Z1,2))
    now converting to MONTH/DAY/YEAR
    = 6/06/1920

    This returns wrong year!
    Any help would be greatly appreciated

    Regards

    Tony

    • I assume that after the phrase Randwick Saturday, 06 June 2020, you still have a space. As a result, the text 06 June 2020 also has a space, that is, “06 June 2020”.

      I recommend checking this or using a formula with the TRIM function:

      =TRIM(MID(Z6,MIN(IFERROR(MIN( FIND({0,1,2,3,4,5,6,7,8,9},Z6&"0123456789",1)), LEN(Z6)+1)), LOOKUP(1,0*MID(Z6,ROW(INDIRECT("1:"&LEN(Z6))),1), ROW(INDIRECT("1:"&LEN(Z6))))+1))

      Now the date format function will work correctly.

      • Tony O'Brien says:

        Hi Alexander
        I tried the formula but still didn't get the date 6-06-2020.

      • Tony O'Brien says:

        Hi Alexander
        Sorry I got cut off, but to finish.
        There is a space between all texts & date plus at the end of years as well.
        In the formula there has space in where FIND, LEN & LOOKUP is, so cancel space ,but still didn't work. Tried { } as well.

        Regards

        Tony

        • Hello!
          I used your formulas and copied the text from your message. As I understand it, the first formula is written in cell Z1.

          =TRIM(MID(Z6, MIN(IFERROR(MIN(FIND({0,1,2,3,4,5,6,7,8,9},Z6&"0123456789",1)), LEN(Z6)+1)), LOOKUP(1,0*MID(Z6,ROW(INDIRECT("1:"&LEN(Z6))),1), ROW(INDIRECT("1:"&LEN(Z6))))+1))

          My second formula works when the formula is written in Z1

          I noticed that your second formula incorrectly determines the month. Use this formula

          =DATEVALUE(LEFT(Z1,2)&"-"&MID(Z1,4,3)&"-"&RIGHT(Z1,4))

    • Hello Stan!
      You do not need to change the date format. You need to add the condition to the formula.
      If I understand your task correctly, the following formula should work for you:

      =IF(A1>TODAY(),-DATEDIF(TODAY(),A1,"d"),DATEDIF(A1, TODAY(),"d"))

      I hope my advice will help you solve your task.

    maybe because the images were cropped more loosely so it's easier to tell which project it was at quick glance. Now the image is cropped closer, making it
    harder to scan thru at quick glance. I find myself needing to click into the project more often than usual. Which makes the whole user experience less
    efficient.
    I have a couple suggestions that might make it work better:
    1. Increase the height of the window the cover image is being displayed.
    2. Let us to choose which image to be displayed as "cover" (like how Pinterest handles cover images of each board, was hoping for this for a long time)
    3. Let us adjust which part of the image to show and how tight or loose the crop is (with a fixed window, let us move the image around and maybe enlarge or
    shrink it to control what shows thru the window. Pinterest does a limited form of this, which is very useful in making the cover image relevant)
    4. Allow Cover Image to be ordered in different hierarchy (currently every element can be ordered differently except the Cover Image, it seems to be stuck
    in the 2nd spot, would like the option to set it on another spot in the layout. This one seems like an easy fix, since you guys allow that for every other
    element already)

    Hello, I'm looking for a rather unique situation with dates in excel and uploading the spreadsheet to a e-commerce website with valid information.

    I currently have a heap of information in a .xlsx file and all works well except for date formatting. I have =NOW() which returns today's date in 25/06/2020. But when I copy the page and paste the values into a .csv file for upload it converts it to 44007.7716459491.

    The other issue is the site will not accept 25/06/2020 as a valid date format but it will accept 25.06.2020.

    Is there an easy formula to produce 25.06.2020 as an auto date, then also create another auto date +30 days in the same 25.07.2020 format?

    Or will I have to create different cells generating the date(A1), month(A2) and year(A3) and then combine them in the cell like =A1&"."&B1&"."&C1 ?

    Hello Team,
    Kudos on writing such a detailed and descriptive tutorial on this topic. It was really helpful.
    My question is regarding the topic "Creating a custom date format in Excel"
    I am able to create a custom format however it only remains in the Excel file I was working on.
    Is it possible to save that custom format so that its available as an option in any Excel file I work on? I just need this as an additional option and don't want to change the default date formats.
    Thanks.

    Hello Sir,
    I have a whole sheet of Excel Data. In that, there a couple of columns where the dates are shown in the format, for eg (10 Dec 1990). I want to change that to the format as 10-12-1990. I tried Format cells and it worked on 1 cell.
    Is it possible to apply it to the entire column at once?? Apply that formula to the entire column of the worksheet?? It might take me ages to change the date format in each and every cell.

    I want my dates to display in yyyymmdd format. I created it in custom but for 20200709 it returns with a value overflow (###### etc.) Is the format I want possible?

    • Hello!
      You entered 20200709 in your cell. This is not a date, but a number. Enter the date correctly. How to enter the date in the cell - read here

      • MauriceN says:

        Thank you for the answer Mr. Trifuntov.
        Alright, than I asked the wrong question.
        I want to enter my dates according to this format: yyyymmdd (so, 20200709), without the usual slashes or hyphens (2020/07/09 or 2020-07-09) because it is easier.
        Is there a way to make excel interpret 20200709 as a date or is there a way to add an entry-format in Excel?

        • Hello!
          You can enter a date in a cell without slashes and hyphens using the VBA macro. Or you can enter a number in another cell and then convert it in the cell you need to a date using Excel functions. You can read more about converting numbers to dates here.

          • MauriceN says:

            Thanks!
            This is exactly what I need. So simple, I should have been able to figure this out for myself!
            Sorry to have bothered you. :-)

    Hi can someone pls help me with an non responsive date change / sort order issue before I throw my computer out the window?

    I've spent over half an hour trying to sort this excel file (link below) into the correct date order. Its back to front and has all the latest dates at the top of the file instead of the bottom. Why is it back to front with the newest yahoo finance data at the top when I web query Yahoo?

    Why does excel not recognise that I am changing the date format to DMY so I can put it in the correct order with oldest dates at the top???

    Column A dates are ompletely unresponsive no matter how many specialist help resources I watch. What am I missing??

    Thanks in advance.

  41. Skip Anderson says:

    If I enter a date as 12/19/1922, my date columns are formatted to display, 19 Dec 1922. If I enter a date prior to 1900, however, the formatting will not change.
    Also, I need to calculate the age of a person and I use =datedif(xx,xx,"y"). But, again,. the calculation won't work for any date prior to 1900.
    Is there a fix for both the formatting issue and the calculation?
    Thanks in advance for your help.

    • Hello!
      Excel does not work with dates before 1900. These dates are recorded as text. Therefore, it is not possible to apply the date format to them.
      To find the difference between dates before 1900, it is recommended to add 2000 years to each of them.
      You can use something like this:

      =DATEDIF(DATEVALUE(LEFT(A1,6)&(RIGHT(A1,4)+2000)),DATEVALUE(LEFT(A2,6)&(RIGHT(A2,4)+2000)),"y")

      If there is anything else I can help you with, please let me know.

  42. Princeton says:

    I do not know what I am doing wrong. I have imported dates into Excel as text values, however, using neither Excel's DATEVALUE function nor Text to Columns feature seems to work.

    In my spreadsheet, the dates are in column F and have the format "m/d/yyyy h:mm:ss AM/PM"

    For example, cell F2 contains the following text: ‎9‎/‎30‎/‎2020 ‎12‎:‎00‎:‎00‎ ‎AM

    I am able to use TRIM(LEFT(F2,FIND(" ",F2)-1)) to retrieve the date portion of the text, but when I attempt to use DATEVALUE(TRIM(LEFT(F2,FIND(" ",F2)-1))) to convert the text value to a date value, I receive a #VALUE! error.

    Please help.

    • Hello!
      Your formula is written correctly and should work. If you imported dates from another program, there may be various non-printable characters in the text. To check this, try manually entering the same information into the cell 9/30/2020 12:00:00 AM
      You can also try using this formula

      =DATE(--MID(F2,FIND("~",SUBSTITUTE(F2,"/","~",2),1)+1, FIND(" ",F2,1)-FIND("~",SUBSTITUTE(F2,"/","~",2),1)-1), --LEFT(F2, SEARCH("/",F2,1)-1), --MID(F2,FIND("~",SUBSTITUTE(F2,"/","~",1),1)+1, FIND("~",SUBSTITUTE(F2,"/","~",2),1)-FIND("~",SUBSTITUTE(F2,"/","~",1),1)-1))

      I hope it’ll be helpful.

    Hello

    I have this format on cell A1: Sep 22, 2020 03:09:09 AM
    What formula do i need to us to change it to: 09/22/2020 and remove the time in cell A2

    thank you in advance

    • Hello!
      If I understand your task correctly, the following formula should work for you:

      =DATE(MID(A1,FIND("~",SUBSTITUTE(A1," ","~",2),1)+1,4), VLOOKUP(LEFT(A1,3), {"JAN",1;"FEB",2;"MAR",3;"APR",4;"May",5;"JUN",6;"JUL",7;"AUG",8; "Sep",9;"OCT",10;"NOV",11;"DEC",12},2,0), MID(A1,FIND(" ",A1,1)+1,2))

      I hope it’ll be helpful.
