In this article we will learn about how to calculate years, month, days in between two dates in Microsoft Excel 2010.

In order to calculate the time passed from a certain date, we will use a birth date as an example

Enter birthday date in cell A1: 01/01/1980
To calculate the number of years from the date, enter the following formula in cell B1: =YEAR(TODAY())-YEAR(A1)

The result (rounded): 23 Years

For a decimal solution, use the following formula: =DATEDIF(A1,TODAY(),”m”)/12

The result: 23.25 Years
To calculate the number of months from the date, enter the following formula in cell D1: =DATEDIF(A1,TODAY(),”m”)

The result: 279 Months

To calculate the number of days from the date, enter the following formula in cell E1: =DATEDIF(A1,TODAY(),”d”)

The result: 8499 Days


PS: A lot of site, avoid to calculate date in Excel using DATEDIF function, due to some of bugs, as DATEDIF function dont have any documentation in Excel Help file,

But, Microsoft continuously giving this feature / formula in all new version.

In case if you also want to avoid DATEDIF function, you can use manual age calculation in excel.. like below…

=INT((TODAY()-A1)/365.25) & ” years , ” & INT(MOD((TODAY()-A1)/365.25,1)*12) & ” months and ” & INT(MOD((TODAY()-A1)/30.4375,1)*30.4375) & ” days”

it will give day difference in Year Month and in days. You can use A2 in case of today, where A2 is the greater day that A1  and gives you Elapsed time between these 2 dates..

This will work like age calculator.



You can see the function has return the number of years, month and days in between two dates. You can use this formula in 2007 and later versions of  Microsoft Excel.

  3. I work in human resources and I am trying to keep track of how many years my employees have been with us at any given time. I have not been able to figure out how to get the elapsed years between the two dates. I have manually done the DATEDIF function, and yes it gives me the desired answer but if I change the current date, the amount of years does not automatically update. I am getting really frustrated so please help. Also if you can reply by email that would be wonderful. Thank you so much.

    • =INT((TODAY()-A1)/365.25) & ” Yrs , ” & INT(MOD((TODAY()-A1)/365.25,1)*12) & ” Mths”


  4. I work in a school setting in special education and each child must have a new evaluation every three years.

    I need a formula to count down the remaining time between evaluations and that would show the evaluations already done from a given date as a negative number or different color or something. Results need to be in a year/month/day or format.

  5. sir i have an problem with my work.i want to send my work by automatically. if we do not done today work so how can i send it to next day.

  6. I’m trying to calculate three date ranges so I used the following formula but it is off by 1.5 years:

    =INT(((B4-A4)+(B5-A5)+(B6-A6))/365.25) & ” years, “& INT(MOD((B4-A4)+(B5-A5)+(B6-A6)/365.25,1)*12) & ” months and “&INT(MOD((B4-A4)+(B5-A5)+(B6-A6)/30.4375,1)*30.4375) &” days”

    Any suggestion?

  7. I am trying to put in a conditional format that shows red when 3 years is up on a date already in the spreadsheet. Can you help?

  8. So, I keep trying to use this formula to give me “years, months, and days”; it is giving me nothing but errors (#NAME?) . I even tried to emulate your exact numbers and not working. Is there something I’m missing? Did the formula on here have extra spaces? This is a feature I would absolutely love to be able to use for my company.

  9. Try this formula, it actually works. S104 is the date you are counting from, you can replace the (TODAY()) Reference with another cell containing a date. As mentioned there are issues with the DATEDIF formula, missing days etc, but is accurate for most uses.

    =DATEDIF(S104,(TODAY()),”y”) & ” years, ” & DATEDIF(S104,(TODAY()),”ym”) & ” months, ” & DATEDIF(S104,(TODAY()),”md”) & ” days”

  10. Hi, I’m trying to perform what should be quite a simple function in Excel.
    I have 3 columns –
    Invoice Date : Payment Terms (Days) : Payment Due
    The values of these columns are -
    05/01/15 : 30 : ???
    How do i work out what the payment due date is in excel via a formula?

    Would love some help here – struggling to create the right formulas for this one – I’m quite a basic user and this uses some differing numerical formats.

    Many thanks!
