How to insert dates in Excel - add today's date, auto fill a column with dates

This tutorial demonstrates various ways of entering dates in Excel. See how to insert today's date and current time as static time stamp or dynamic values, how to auto populate a column or row with weekdays, and how to auto fill random dates in Excel.

There are several ways to add dates in Excel depending on what exactly you want to do. For example, do you want to enter a today's date in some report or invoice? Or, perhaps you want to insert a date in Excel that will update automatically and always display the current date and time? Or, maybe you want to auto fill weekdays or input random dates in your worksheet?

In a moment, you will learn all these and a few more date entering techniques. If you are curious to know how Excel stores dates and times, please check out part 1 of this tutorial - Excel date format.

How to enter a date in Excel

You can type a date in an Excel cell in a variety of ways, for example 1/1/2015, or 1-Jan-2015, or 1-Jan, or January 1, 2015. When you type something like that in a cell, Microsoft Excel knows you are entering a date and automatically applies the date format to that cell. Quite often, Excel formats the newly inserted date according to your Windows default date settings, but sometimes it may leave it exactly as you typed.

The most obvious visual indication that Excel has recognized the date you've entered is its right-alignment in a cell as opposed to left-aligned text values.
Various ways to enter a date in Excel

If Excel has failed to recognize your input as a date and you see it left-justified in a cell, try inserting a date in some other format close to your default short or long date formats. These formats are marked with an asterisk (*) in the Format Cell dialog window and you can quickly access them on the Excel ribbon (Home tab > Number group):
The default short or long date formats in Excel

You will be able to easily change the date format later via the Format Cells dialog that opens on the Ctrl + 1 shortcut. For more details, please see How to change the date format in Excel.

Note. If a date you've entered displays as a number of pound signs (#####) in a cell, most likely the cell is not wide enough to fit the entire date. To fix this, double-click the right border of the column to auto fit the date, or drag the right border to set the desired column width. If this does not help, please check other Excel date format troubleshooting tips.

Tip. The fact that Excel automatically recognizes the entered value as a date may not always be what you actually want. We have some tips on how to avoid automatic data formatting.

Inserting today's date and current time in Excel

In Microsoft Excel, you can input the current date and time either as a static or dynamic value.

Shortcuts to enter today date in Excel (as a timestamp)

To begin with, let's define what timestamp is. Timestamping is entering a "static date" that won't change with the course of time or when the spreadsheet is recalculated.

So, if your goal is to enter the current date and/or time as a static value that won't automatically update the next day, you can use one of the following shortcuts:

  • Ctrl + ; shortcut inserts the today date in a cell.
  • Ctrl + Shift + ; shortcut inserts the current time.
  • To enter the current date and time, press Ctrl + ; then press the Space key, and then Ctrl + Shift + ;.

The shortcuts to insert today's date in Excel

Insert an automatically updatable today's date and current time

If you want to input today's date in Excel that will always remain up to date, use one of the following Excel date functions:

=TODAY() - inserts the today date in a cell.

=NOW() - inserts the today date and current time in a cell.
Inserting an automatically updatable today's date and current time

Unlike Excel date shortcuts, the TODAY and NOW functions will always return today's date and current time.

When using the Excel date functions, please keep in mind that:

  • The returned date and time are not refreshed continuously, they are updated only when the spreadsheet is re-opened or re-calculated, or when a macro containing the function is run.
  • The functions take the current date and time from your computer's system clock.

How to insert today date & current time as unchangeable time stamp

This section addresses a handful of comments that have been posted on this page with one and the same question: "What formula do I use to enter a timestamp in my Excel sheet without it changing every time the worksheet is reopened or recalculated?"

For starters, I'd like to note that I'm very hesitant to post this solution because it involves circular references, and they should be treated with great care. Anyway, here goes the formula…

Let's say you have a list of items in column A, and as soon as a certain item is shipped, you enter "Yes" in the Delivery column, which is column B. Once "Yes" is in there, you want to have the current date and time automatically inserted in the same row in column C as a static unchangeable time stamp.

To do this, we are going to use the following nested IF formula with circular references in the second IF function:

=IF(B2="yes", IF(C2="" ,NOW(), C2), "")

Where B is the Delivery column, and C2 is the cell where you input the formula and where the time stamp will eventually appear.
A circular formula to insert a time stamp in Excel

In the above formula, the first IF function checks cell B2 for the word "Yes" (or any other text you supply to the formula), and if the specified text is there, it runs the second IF function, otherwise returns an empty string. And the second IF is a circular formula that makes the NOW function return the current day and time if C2 doesn't have a value in it already, thus saving all existing time stamps.

If instead of checking for any specific word, you want the timestamp to appear when you put anything in the specified cell (that could be any number, text or date), then have the first IF function to check for a non-empty cell, like this:

=IF(B2<>"", IF(C2="" ,NOW(), C2), "")

Note. For this Excel circular formula to work, you should allow iterative calculations in your worksheet. Also, please keep in mind that there are many reasons not to use circular references in Excel, and if you decide to apply this solution in your worksheets, it's on your own risk.

How to auto populate dates in Excel

If you need to insert dates in a range of cells, you can let Excel "auto date" a column or row by using the AutoFill feature as demonstrated below or make a date sequence with formulas as explained in the above-linked tutorial.

Auto fill a date series that increases by one day

To automatically fill a column or row with an incrementing date series that increases by one day, you use Excel's AutoFill feature in the usual way:

  1. Enter your initial date in the first cell.
  2. Click on the cell with the first date to select it, and then drag the fill handle across or down the cells where you want Excel to add dates. (The fill handle is a small green square that appears at the bottom-right corner when you select a cell or a range of cells in Excel, as shown in the screenshot below.)

Auto filling a date series that increases by one day

Auto fill weekdays, months or years

There are two ways to automatically populate the selected range of cells with weekdays, months or years.

  • You can use the Excel AutoFill options as described above. When the range is populated with sequential dates, click the AutoFill Options icon and select the option you want:
    This is how you auto fill weekdays in Excel.
  • Another way is to enter your first date, right-click the fill handle and drag the fill handle through the cells you want to auto fill with dates, and then release it. When you do, Excel displays a context menu and you select the appropriate option from it.
    Another way to auto populate weekdays, months or years in Excel

Auto insert every 2nd, 3rd or Nth day

If you've tried a second solution described above, you probably noticed the Series option near the bottom, which provides a few more auto date features. One of them is inserting every 2nd, 3rd, 4th, etc. day, month or year in a worksheet. Let's try this now:

  1. Add the first date in some cell.
  2. Select that cell, right-click on the fill handle, drag it down or across several cells, and then release.
  3. In the context menu, click Series.
  4. In the Series dialog box, choose the appropriate Date unit and enter the Step value.
  5. Click OK.

Inserting every 2nd, 3rd or Nth day automatically

How to inset random dates in Excel

Regrettably, Microsoft Excel does not provide an option to enter random dates automatically. Luckily, AbleBits Random Generator for Excel does :)

You simply select a range of cells where you want to autofill dates in a random order, and switch to the Random Generator's pane where you specify:

  • Start and End date;
  • What days to add - weekdays, weekends or both;
  • To add only unique dates, check the Unique values

Then you click the Generate button, and have the selected range populated with random dates.
Inserting random dates in Excel

Apart from dates, the Random Generator add-in can auto fill your worksheets with numbers, Boolean vales and custom lists. If you think this is something that would be useful in your work, you can get it as part of our Ultimate Suite for Excel that includes 70+ time-saving tools and over 300 useful features.

If you are setting up a spreadsheet for other users, and want to make sure they enter dates right, it may be a good idea to insert a drop-down calendar in a worksheet. Your users will be able to fill in dates in a mouse click and you will be 100% confident that all dates are entered in an appropriate format.

If you are using a 32-bit version of Excel, you can use Microsoft's Date Picker control. For the detailed instructions, please see How to insert calendar in Excel (Date Picker control).

If you are using a 64-bit version of Excel 2016, Excel 2013, Microsoft's Date Picker control won't do. In this case, consider using one of the third-party calendars, for example our own one :)

Ablebits drop-down calendar for Excel

This is how you insert date in Excel. I am hopeful these date entering techniques, shortcuts, functions and Excel auto date features have proved useful to you. Anyway, thank you for reading!

  1. Hi, I thought it was worth mentioning here and hopefully and workaround can be found.
    I used your formula to auto date stamp a cell when data is entered in another …… =IF(B21"",IF(A21="",NOW(),A21),"")
    And a slightly different version…. =IF(B1"",IF(A1"",A1,NOW()),"")

    This is the scenario where the problem is occurring.
    I input data on the sheet using excel on my phone, date stamps are all correct and the excel file saved on my one drive account. Few days later I will open the same excel file on my iPad. When excel updates the cells with the most recent information (the info stored previously from the phone) It populates the cells but the formula sees that as the date it was inputted… not the original date stamp that was created at the time of inputting the original dat on my phone.

    Wonder if there is any work around or fix for this that doesn’t require macros as they are not compatible on mobile devices.
    Cheers
    Matt

    1. Hello Matt!
      If I understand your task correctly, to prevent your date from automatically changing, you can use several methods:
      1. Use Shortcuts to insert the current date and time
      2. Use the recommendations How to insert today date & current time as unchangeable time stamp in our blog.
      3. Replace the date and time returned by the TODAY function with their values. Copy the date (CTRL + C), then paste only the values using Paste Special or Shortcut CTRL + ALT + V.
      4. Use VBA to write the current time to the cell.

      1. Thanks for your quick reply. :-)

        Your example works brilliant on an Excel sheet stored locally.. but not files stored on a cloud. This is to do with how data is updated between devices.

        I have originally followed the example in the above blog (https://www.ablebits.com/office-addins-blog/insert-dates-excel/#insert-timestamp)

        However this doesn’t work all the time when it comes to saving the file to the cloud (one drive) and loading / editing it from different devices.

        The reason for this is as follows:
        Example:
        Data added to cell B1 via excel on iPhone. Date stamp eg 1/2/24 added to cell A1. Excel sheet now saved back to cloud (one drive).

        2 days later open the same file on a different ios device….
        It opens the file, sees that data has been inserted into B1 but sees the same formula in A1 as before, excel then proceeds automatically populates cell B1 with that new data from the version stored in the cloud. So from that sheets perspective it’s the first time data is been entered into cell B1 and therefor it adds the date stamp from when it’s got the data. In this examples case 3/2/24

        Keyboard shortcuts or VBA won’t work on iOS

        If I only open and edit the sheet on one iOS device it would all work flawlessly but crossing devices using cloud storage causes problems. Real shame as it was so handy having the auto date stamp function.

  2. I want whole date in words like fourteen February two thousand eight. how can I get this in excel?

    1. Hi! This is not possible with the standard Excel options. This can be done using a VBA macro or a custom user-defined function.

  3. for b3 provide formula, if anything is typed in c3, display the date of that day and make it static

    1. Hello! If I understand your task correctly, read the following paragraph in the article above very carefully: How to insert today date & current time as unchangeable time stamp.
      The second option is to use VBA to write the current date and time to the cell.

  4. Hello,

    I was wondering how to autofill a list of dates based of previous excel columns. Basically, I had my month, date and year all as separate columns on excel and I want to combine all those columns into one on excel with the full date. All the dates the randomized as they are birthdates. If there is a faster way to do this rather than fix it manually please let me know!!

  5. Hello,

    I am using the circular reference method to insert a "Date Entered" timestamp for each row of an inventory sheet to highlight the time the material in that row was entered into the sheet. I also was hoping to create another column with a timestamp that updates automatically, "Date Modified" if something on that row was changed after being entered, but I am having a hard time with it. I tried something similar to this =IF(A7:D7="","",NOW()) and it sort of works, but when any cell within the spreadsheet is changed, it updates that entire column rather than just the corresponding value in that row. Is this something that is doable? I know you can do it in VBA but this is for a spreadsheet that most people will use with the web version of Excel and we don't have access to macros that way.

    1. Hi! To fix the date of the change, you must specify the current value that was changed in the formula, not "". Or use VBA.

  6. Hi Svetlana,

    For some reason this formula is not working for me. I am getting a 0 value instead of date. Can you please help what could be the issue?

    =IF(B2="yes", IF(C2="" ,NOW(), C2), "")

    1. Hi! Follow all the recommendations that are given to this formula. For example, allow iterative calculations, and others.

  7. Hi! How do I get the very next cell to generate a date that is 5 business days (or 7 days) out from the date in the previous cell? For example, if I put a date of 11/10/2023 in cell B2, is there a way to get cell C2 to automatically generate a date of 11/17/2023? Either by auto-populating as if there were a formula, or by dragging and auto-filling?

    I need a way to easily track and populate due dates that are 5 business days out from the date that will be input in column B.

    Thank you!!

    1. This is exactly what I needed. Thank you!!

  8. I wont to enter the date if not entered return today function in excel ?

    =SUMIFS(Consolidated[Amount Needed],Consolidated[Paint],[@Coat],Consolidated[Date],IF(P3="DATE",IF(P3="",NOW(),P3),""))
    =SUMIFS(Consolidated[Amount Needed],Consolidated[Paint],[@Coat],Consolidated[Date],IF(ISBLANK(P3),"",TODAY()-P3))

    Which of these statements is true?
    Why does it always return this result? 00/01/1900

    1. Hi! It is very difficult to understand a formula that contains unique references to your workbook worksheets. Hence, I cannot check its work. Your result means 0 in date format.

  9. Thank yoe so much Svetlana, This was very helpful!

  10. Hi There,

    I am trying to create a formula to say IF D3=1st day of the month then E3 should be same date as D3 if any other day of the month then E3 should be 1st day of following month is this possilbe ?

    I can get it to do E3 as following month or 3 months later but I can't figure out the if E3 =1st day to enter same as E3 1st day of the month?

    I hope you can help
    Tara

  11. hi, I have a dropdown in column F and when this is updated i want todays date to be added into column D. i also need that once column F is still filled in and is then changed that the date in column D will also update into todays date. example

    dropdown- Column F
    call answered
    no answer

    Column D
    11/10/2023

    tomorrow i change the disposition from call answered to no answer and need the date to go from 11/10/2023 to now 12/10/23

    1. Hi! I'm really sorry, looks like this is not possible with the standard Excel options. Try to use VBA code.

  12. I have a dropdown in A2. If I choose an option, say Break1, I want the time of Break 1 to be recorded in B2. If I choose Lunch on A3, I want the time of Lunch to be recorded in B3. I used the NOW function in B column and every time I choose an option in A column, the time changes. I simply want to record the time every time I choose something in A column. For example, Break 1 in A2 will have its own time in B2, Lunch in A3 will have its own time in B3, Break 2 option in A4 will have its own in B4, and so on).

  13. HI,
    I tried the formula
    =IF(B3"", IF(A3="",TODAY(), A3),"")

    but it only returns this date 01/00/1900
    i already allowed iterative calculations and auto calculations... but same output

    if just use =today() in the same cell it returns the current date which what i want to display... any help will be appreciated thanks

    1. Hi! I can't check your formula without your data, but the date 01/00/1900 means your formula returns 0.

      1. I am working on a weekly report which is to be due on Mondays, I want a particular cell to show the date of each Monday my report will be due without me manually changing or editing it. How do I go about this?

  14. Hey!

    i see this community has alot of information so i was wondering if anyone can assists over here

    Im creating a mortgage spreadsheet for reminders when mortgages are due. how can i set that the due date automatically changes each month or quarter once the date has passed and that the cell turn red 1 week prior to that date.

    thanks

    1. Hi! To highlight a cell with a color based on the current date, use these instructions: Conditionally format dates based on the current date.
      Conditional formatting formula 7 days before a specific date:

      =AND($C1-TODAY()>=0,$C1-TODAY()<=7) - highlight all cells where the End Date (column C) is within the next 7 days.

      Each month, you can automatically add a month to the start date with this formula:

      =DATE(YEAR(D1),MONTH(D1)+DATEDIF(D1,TODAY(),"m")+1,DAY(D1))

  15. How can I write a date which would start with 0, for example 01/06/1995, without using any special characters or without making it a text?

      1. So I have used all the methods from that tutorial but I am not able to get the exact date I want. It's either showing some random date or random number or ######### like that after using the methods.

        1. Hi! I don't know what date you are writing in the cell. What it means: "date which would start with 0, for example 01/06/1995"? If you actually have a date in a cell, you will have no problem changing its format. Please read the above article carefully.

  16. Hello,
    How can I:
    1. Make a cell automatically fill a date based on the timeframe from a date that has been input into another cell e.g three months after original cell date.

    2. How can I make a cell change colour if the date inputted in another cell is within a certain time frame of the current date?

  17. How do I create and excel sheet to generate the next date every time I open for example today is 8/16/2023 tomorrow when I open open the excel I would like for it to populate that date automatically to 8/17/2023 so I wouldn't have to change it myself

    1. Hi! Pay attention to the following paragraph of the article above: Insert an automatically updatable today's date and current time.

  18. What formula can I use to auto populate todays date in the format of Tuesday, August 01, 2023

  19. Hi,

    I want to control particular cell editable or not editable using condition ( If cell A1=1 then B1 is editable and if A1=0 B1 is not editable).
    Please help me.

    1. Hi! We have said many times that an Excel formula can only have an effect on the cell in which it is written. Your task is solved using VBA.

  20. Hello, thank you for the formula. I have used this with a drop down list, so when a certian drop down is selected, it will insert the date/time stamp. However, once the drop down is changed again, the date/time stamp goes away. What could I be doing wrong?
