Using DATE function in Excel - formula examples to calculate dates

When it comes to calculating dates in Excel, DATE is the most essential function to understand. As you probably know, Excel does not keep the year, month and day for a date, nor does it explicitly store weekday information in a cell. Instead, Microsoft Excel stores dates as serial numbers and this is the main source of confusion.

Not all Excel date functions can recognize dates entered as text values, therefore it's not recommended to supply dates directly in calculations. Instead, you should use the DATE function to get a serial number representing the date, the number that Excel understands and can operate on.

Excel DATE function

The Excel DATE function returns the serial number that represents a certain date. It has the following arguments:

DATE(year, month, day)


Year - represents the year of the date.

Month - an integer representing the month of the year, from 1 (January) to 12 (December).

Day - an integer corresponding to the day of the month, from 1 to 31.

The DATE function is available in all versions of Excel 365 - Excel 2007.

DATE function - tips and notes

The DATE syntax looks crystal clear and straightforward on the surface. In practice, there may be some unobvious pitfalls that the below tips will help you avoid.


Excel interprets the year argument according to the date system set up on your computer. By default, Microsoft Excel for Windows uses the 1900 system where January 1, 1900 is represented by the serial number 1. For more details, please see Excel date format.

  • If the year argument is between 1900 and 9999 inclusive, Excel uses exactly the value you supplied to create a date. For example, DATE(2015, 12, 31) returns December 31, 2015.
  • If the year argument is between 0 and 1899 inclusive, Excel adds the specified number to 1900. For example, DATE(100, 12, 31) returns December 31, 2000 (1900 + 100).
  • If the year argument is less than 0 or greater than 9999, a DATE formula will return the #NUM! error.

Tip. To avoid confusion, always supply four-digit years. For example, if you input "01" or "1" in the year argument, your DATE formula will return the year of 1901.


  • If the month argument is greater than 12, Excel adds that number to the first month in the specified year. For example, DATE(2015, 15, 5) returns the serial number representing March 1, 2016 (January 5, 2015 plus 15 months).
  • If the month argument is less than 1 (zero or negative value), Excel subtracts the magnitude of that number of months, plus 1, from the first month in the specified year. For example, DATE(2015, -5, 1) returns the serial number representing July 1, 2014 (January 1, 2015 minus 6 months).


As well as month, the day argument can be supplied as a positive and negative number, and Excel calculates its value based on the same principles as described above.

Tip. At first sight, supplying negative values in the month or day argument of the Excel DATE function may seem absurd, but in practice it may turn out quite useful, for example in the complex formula that converts a week number to a date.

Excel DATE formula examples

Below you will find a few examples of using DATE formulas in Excel beginning with the simplest ones.

Example 1. DATE formula to return a serial number for a date

This is the most obvious use of the DATE function in Excel.

For example, to return a serial number corresponding to 20-May-2015, use this formula:

=DATE(2015, 5, 20)

Instead of specifying the values representing the year, month and day directly in a formula, you can have some or all arguments driven by of other Excel date functions. For instance, combine the YEAR and TODAY to get a serial number for the first day of the current year.

=DATE(YEAR(TODAY()), 1, 1)

And this formula outputs a serial number for the first day of the current month in the current year:

Using the DATE function in Excel to get a serial number representing a date

Tip. To display a date rather than a serial number, apply the desired Date format to the formula cell.

Example 2. How to return a date based on values in other cells

The DATE function is very helpful for calculating dates where the year, month, and day values are stored in other cells.

For example, to find the serial number for the date, taking the values in cells A2, A3 and A4 as the year, month and day arguments, respectively, the formula is:

=DATE(A2, A3, A4)
Excel DATE formula to return a date based on values in other cells

Example 3. DATE formula to convert a string or number to a date

Another scenario when the Excel DATE function proves useful is when the dates are stored in the format that Microsoft Excel does not recognize, for instance DDMMYYYY. In this case, you can use DATE in liaison with other functions to convert a date stored as a numeric string or number into a date:

=DATE(RIGHT(A2,4), MID(A2,3,2), LEFT(A2,2))
DATE formula to convert a string to a date

Example 4. Adding and subtracting dates in Excel

As already mentioned, Microsoft Excel stores dates as serial numbers and operates on those numbers in formulas and calculations. That is why when you want to add or subtract some days to/from a given date, you need to convert that date to a serial number first by using the Excel DATE function. For example:

  • Adding days to a date:=DATE(2015, 5, 20) + 15The formula adds 15 days to May 20, 2015 and returns June 4, 2015.
  • Subtracting days from a date:=DATE(2015, 5, 20) - 15The result of the above formula is May 5, 2015, which is May 20, 2015 minus 15 days.
  • To subtract a date from today's date:=TODAY()-DATE(2015,5,20)The formula calculates how many days are between the current date and some other date that you specify.

DATE formulas to add and subtract dates in Excel

If you are adding or subtracting two dates that are stored in some cells, then the formula is as simple as =A1+B1 or A1-B1, respectively.

For more information, please see:

Advanced Excel DATE formulas

And here are a few more examples where Excel DATE is used in combination with other functions in more complex formulas:

Using Excel DATE formulas in conditional formatting

In case you want not only to calculate but also highlight dates in your Excel worksheets, then create conditional formatting rules based on DATE formulas.

Supposing you have a list of dates in column A and you want to shade dates that occurred earlier than 1-May-2015 in orange and those that occur after 31-May-2015 in green.

The DATE formulas you want are as follows:

Orange: =$A2<DATE(2015, 5, 1) - highlights dates less than 1-May-2015

Green: =$A2>DATE(2015, 5, 31) - highlights dates greater than 31-May-2015

  1. Hii Concern,

    I just wanted a formula for example,
    ending date of one card is like 25/08/2018 and one more card for the same person expiry date is like 26/09/2018 and the output i need is like
    by adding +60 days for first card and by adding +30 days for second card i need output is which ever less date will comes that date i need as output,
    can someone pls suggest.

  2. Hi,
    I would like to know the formula to get the below requirement

  4. I was wondering if you could help me with a calculation. I need to be able to calculate 14 hours out of every 24 hour period from dates and times entered in 2 cells. For example cell A1 would have 4/10 13:00, cell B1 would have 4/12 18:00. I know how to do the total hours calculation, but we only pay for 14 hours out of every 24 hours with a 2 hour and 6 hour grace period. I need a formula to do this. The total hours would be 53. So I would need cell D1 to = 31 and cell E to = 28 For D1 we would need the calculation to show 4/10 15:00 - 4/11 15:00 = 14 hours paid, 4/11 15:00 - 4/12 15:00 = 14 hours paid, 4/12 15:00 - 4/12 18:00 = 3 hours paid...for a total of 31. For E1 it would be 4/10 19:00 - 4/11 19:00 = 14 hours paid, 4/11 19:00 - 4/12 18:00 = 14 hours paid...for a total of 28. Can this be done or is it possible to create a macro that would do this?

  5. I am working on a spreadsheet that I am using the following formula. =COUNTIFS(REWORK!C:C,"BOM Error",REWORK!A:A,"=12/17/17") How can I incorporate the date function into the formula to avoid having to try to change for each line?

    Hex (0X62 0X68 0X8A 0X2D).

    Here is the data format.

    T4 - encoding 1:

    1. word 3*(365*(Year-1986) + DayNumberInYear) + Hour/8
    2. word 3600*(Hour modulus 8) + 60*Min + Sec

    DayNumberInYear assigns 1 to January the first and increments
    the number by one each day, treating leap-years correctly.
    Unfortunately, this encoding assigns the same 1. word to December 31. in a
    leap-year and January 1. in the next year.

    T4 - encoding 2:

    1. word 3*(366*(Year-1994) + DayNumberInLeapYear) + Hour/8
    2. word 3600*(Hour modulus 8) + 60*Min + Sec + 32768

    DayNumberInLeapYear assigns 0 to January the first and

  10. Here's an old Lotus 1-2-3 method that works great in Excel and will accomplish what you're looking to do:
    =DATEDIF(D2,E2,"y") &" years,"&DATEDIF(D2,E2,"ym") &" months," &DATEDIF(D2,E2,"md") &" days"
    Enter this formula into F2 and it will show the number of years, months and days between the start date and the end date. It looks like this: "3 years,8 months,28 days".
    If you need to sum the years, months and days you may need to enter them into separate columns. If so, just enter the DATEDIF(start,end,"Y") pieces in separate columns minus the "&"Years", etc. part. You'll have only the numbers that you can then sum.

    I am trying to do a summary sheet using cell values from sheet 2. We are calculating number of dogs or cats (2 different columns on the summary sheet so cats will be a separate formula - but they are all mixed together on sheet 2). But I want totals for the month so made that another condition. So 2 IF conditions - column F should equal dog and column A should be between two dates inclusive. I think I have the formula close here but it doesn't like the formatting of my dates. I have tried a few different ways - DATEVALUE, d/m/y, no spaces, quotations. Can you help? Thank you so much!!!

    That pulls a value from the homloans worksheet.

    The problem is the "second date" formula will not allow me to pull the value from homeloans because of the way it is formatted.

    Any suggestions on how I should format the "second date formula" and it still create a dynamic month based on the first month in the series?

  22. I have a doozy for you. based upon the date entered into column A, I want a formula to determine if that date is on or before the 15th of that month. If the date falls within that range then I want it to return a value for that month and year in column B. If the date in column A is after the 15th of that month then I want it to return a value in column B that is for the next month and year. For example: If someone entered 6/2/2017 in column A, then column B would return a value of 6/1/2017. If someone entered 6/16/2017 in column A then column B would return a value of 7/1/2017 in column B.

    • Hello, Sara,

      in addition to the DATE function (to add years) you need to use IF function as well. You will need to built a nested IF in order to go through all your conditions. So the formula should start like this:

      And your nested IF continues :)

  39. Hi Team,

    Your above methods are very helpful.
    I wanted to know how i can get the date of next month.
    For eg-: if i input 23-01-2017 i should get the output 22-02-2017

    • Hi,

      Thank you for your question.

      Enter your date in any cell (A1 in my example) and try the following formula:


      As the logic of the DATE function is the following: DATE(year, month, day), the formula above adds a month to the date in A1. You can change the number of days/mounts/years as needed.

      Please let us know if you have any other questions.

  40. ty so much for your amazing page and information.

    I am trying to create a spreadsheet for my sales tracking. If I ordered a specific document on xx/xx/xx date and have input that date into Column A2 for example(labled -date requested), I will input the received doc. date in column B2.
    But if no document is received. I would like for column B2 to turn green(when column A2 date is input(day1) and yellow when 1 day past the initial A2 date, and red when 2 days or more past the initial A2 date(request date) to inform us that the document has not been received. However, if a date has been inputted into B2 these rules(Red, yellow and green) will stop, because the date was added to B2 therefore implying that the document was received.

  41. I have column D for the date an item is issued. column E will calculate the date from column D plus 180 days. I would like to be able to input the current date into column F. And have it calculate into column G the amount of days between the current date in column G and the due date in column E. If you can help me with formulas I would be greatful

  44. Can I update the cell references in a formula (i.e. add the next months value into the formula) by changing the month in a drop down list? I am looking to extend the formula each month and would like to accomplish this without manually changing every line.

    • Hello, Sean,

      yes, Excel formulas recognize the values chosen from the drop-down list and return the values accordingly. Make sure that you reference the cell with a drop-down list correctly in your formula and it should work.

  49. Hi there,

    I am using a Gantt Chart I made years ago and can't figure out why I created the formula the way I did.


    J5 = is the Start Date (which is 1st of June, 2017)
    M8 = 1 (Day of the week which was Sunday)

    and then I have M1 whose value is 0 <-- this is the part that I needed to remember/understand, why I declared the value as 0
