How to convert date to year in Excel & calculate age from date of birth

This tutorial explains the syntax and uses of the Excel YEAR function and provides formula examples to extract year from date, convert date to month and year, calculate age from the date of birth and determine leap years.

In a few recent posts, we have explored different ways to calculate dates and times in Excel and learned a variety of useful functions such as WEEKDAY, DAY, MONTH and WEEKNUM. Today, we are going to focus on a bigger time unit and talk about calculating years in your Excel worksheets.

In this tutorial, you will learn:

YEAR function in Excel

The YEAR function returns a four-digit year corresponding to the specified date, as an integer from 1900 to 9999.

The syntax of the Excel YEAR function is as simple as it could possibly be:


Where serial_number is any valid date of the year you want to find. In your Excel YEAR formulas, you can specify dates in several ways:

  • Using the DATE For example, the following formula returns the year for 28 April, 2015:
  • As a serial number representing the date (for more information on how dates are stored in Excel, please see Excel date format). The 28 day of April, 2015 is stored as 42122, so you can enter this number directly in the formula:

    Although you can enter a date as a serial numbers, this method is not recommended because date numbering may vary across different systems.

  • As a cell reference, e.g. =YEAR(A1)
  • As a result of some other formula. For example, you can use the TODAY() function to extract the year from the current date:

Simple YEAR formulas can even understand dates entered as text, like =YEAR("28-Apr-2015"). However, Microsoft does not guarantee correct results when a date is supplied as a text value.

The following screenshot demonstrates all of the above YEAR formulas in action, all returning 2015 as you might expect :)

How to convert date to year in Excel

When you work with date information in Excel, your worksheets usually display full dates, including month, day and year. However, for major milestones and important events such as product launches or asset acquisitions, you may want to view only the year without re-entering or modifying the original data. Below, you will find 3 quick ways to do this.

Example 1. Extract a year from date using the YEAR function

In fact, you already know how to use the YEAR function in Excel to convert a date to a year. The screenshot above demonstrates a bunch of formulas, and you can see a few more examples in the screenshot below. Notice that the YEAR function perfectly understands dates in all possible formats:
Excel YEAR formula examples

Example 2. Convert date to month and year in Excel

To convert a given date to year and month, you can use the TEXT function to extract each unit individually, and then concatenate those functions within one formula.

In the TEXT function, you can use different codes for months and years, such as:

  • "mmm" - abbreviated months names, as Jan - Dec.
  • "mmmm" - full month names, as January - December.
  • "yy" - 2-digit years
  • "yyyy" - 4-digit years

To make the output better readable, you can separate the codes with a comma, hyphen or any other character, like in the following Date to Month and Year formulas:

=TEXT(B2, "mmmm") & ", " & TEXT(B2, "yyyy")


=TEXT(B2, "mmm") & "-" & TEXT(B2, "yy")

Where B2 is a cell containing a date.
TEXT formulas to convert date to month and year in Excel

Example 3. Display a date as a year

If it does not really matter how the dates are stored in your workbook, you can get Excel to show only the years without changing the original dates. In other words, you can have full dates stored in cells, but only the years displayed.

In this case, no formula is needed. You just open the Format Cells dialog by pressing Ctrl + 1, select the Custom category on the Number tab, and enter one of the below codes in the Type box:

  • yy - to display 2-digit years, as 00 - 99.
  • yyyy - to display 4-digit years, as 1900 - 9999.

Displaying a date as a year

Please remember that this method does not change the original date, it only changes the way the date is displayed in your worksheet. If you refer to such cells in your formulas, Microsoft Excel will perform date calculations rather than year calculations.

You can find more details about changing the date format in this tutorial: How to change date format in Excel.

How to calculate age from date of birth in Excel

There are several ways to calculate age form date of birth in Excel - using DATEDIF, YEARFRAC or INT function in combination with TODAY(). The TODAY function supplies the date to calculate age at, ensuring that your formula will always return the correct age.

Calculate age from date of birth (DOB) in years

The traditional way to calculate a person's age in years is to subtract the birth date from the current date. This approach works fine in everyday life, but an analogous Excel age calculation formula is not perfectly true:


The first part of the formula (TODAY()-B2) calculates the difference is days, and you divide it by 365 to get the number of years. In most cases, the result of this equation is a decimal number, and you have the INT function round it down to the nearest integer.

Assuming the date of birth is in cell B2, the complete formula goes as follows:

A formula to convert a date of birth to age

As mentioned above, this age calculation formula is not always flawless, and here's why. Every 4th year is a leap year that contains 366 days, whereas the formula divides the number of days by 365. So, if someone was born on February 29 and today is February 28, this age formula will make a person one day older.

Dividing by 365.25 instead of 365 is not impeccable either, for example, when calculating the age of a child who hasn't yet lived through a leap year.

Given the above, you'd better save this way of calculating age for normal life, and use one of the following formulas to calculate age from date of birth in Excel.



The detailed explanation of the above formulas is provided in How to calculate age in Excel. And the following screenshot demonstrates a real-life age calculation formula in action:

=DATEDIF(B2, TODAY(), "y")
A formula to calculate age from date of birth in years

Calculating exact age from date of birth (in years, month and days)

To calculate an exact age in years, months and days, write three DATEDIF functions with the following units in the last argument:

  • Y - to calculate the number of complete years.
  • YM - to get the difference between the months, ignoring years.
  • MD - to get the difference between the days, ignoring years and months.

And then, concatenate the 3 DATEDIF functions in a single formula, separate the numbers returned by each function with commas, and define what each number means.

Assuming the date of birth is in cell B2, the complete formula goes as follows:

=DATEDIF(B2,TODAY(),"Y") & " Years, " & DATEDIF(B2,TODAY(),"YM") & " Months, " & DATEDIF(B2,TODAY(),"MD") & " Days"

This age formula may come in very handy, say, for a doctor to display the exact age of patients, or for a personnel officer to know the exact age of all employees:
Calculating exact age from date of birth in Excel

For more formula examples such as calculating age at a particular date or in a certain year, please check out the following tutorial: How to calculate age in Excel - formula examples.

Calculating leap years in Excel

As you know, nearly every 4th year has an extra day on February 29 and is called a leap year. In Microsoft Excel sheets, you can determine whether a certain date belongs to a leap year or a common year in a variety of ways. I'm going to demonstrate just a couple of formulas, which in my opinion are easiest to understand.

Formula 1. Check if February has 29 days

This is a very obvious test. Since February has 29 days in leap years, we calculate the number of days in month 2 of a given year and compare it with number 29. For example:


In this formula, the DATE(2015,3,1) function returns the 1st day of March in the year 2015, from which we subtract 1. The DAY function extracts the day number from this date, and we compare that number with 29. If the numbers match, the formula returns TRUE, FALSE otherwise.

If you already have a list of dates in your Excel worksheet and you want to know which ones are leap years, then incorporate the YEAR function in the formula to extract a year from a date:


Where A2 is a cell containing the date.

The results returned by the formula are as follows:

Calculating leap years in Excel

Alternatively, you can use the EOMONTH function to return the last day in February, and compare that number with 29:


To make the formula more user-friendly, employ the IF function and have it return, say, "Leap year" and "Common year" instead of TRUE and FALSE:

=IF(DAY(DATE(YEAR(A2),3,1)-1)=29, "Leap year", "Common year")

=IF(DAY(EOMONTH(DATE(YEAR(A2),2,1),0))=29, "Leap year", "Common year")

Use the IF function to make the leap year formula more user-friendly

Formula 2. Check if the year has 366 days

This is another obvious test that hardly requires any explanation. We use one DATE function to return 1-Jan of the next year, another DATE function to get 1-Jan of this year, subtract the latter from the former and check if the difference equals to 366:

=DATE(2016,1,1) - DATE(2015,1,1)=366

To calculate a year based on a date entered in some cell, you use the Excel YEAR function exactly in the same way as we did in the previous example:

=DATE(YEAR(A2)+1,1,1) - DATE(YEAR(A2),1,1)=366

Where A2 is a cell containing the date.

And naturally, you can enclose the above DATE / YEAR formula in the IF function for it to return something more meaningful than the Boolean values of TRUE and FALSE:

=IF(DATE(YEAR(A2)+1,1,1) - DATE(YEAR(A2),1,1)=366, "Leap year", "Non-leap year")
Another way to determine leap and non-leap years in Excel

As already mentioned, these are not the only possible ways to calculate leap years in Excel. If you are curious to know other solutions, you can check the method suggested by Microsoft. (As usual, Microsoft guys are not looking for easy ways, are they?) And you can find 14 other formulas on this blog.

Hopefully, this article has helped you figure out year calculations in Excel. I thank you for reading and look forward to seeing you next week.

    please help me.

    • Supposing that your date of birth is in A1 and the other date in B1, you can use the following formula:

      =DATEDIF(A1, B1,"Y") & " Years, " & DATEDIF(A1, B1,"YM") & " Months, " & DATEDIF(A1, B1,"MD") & " Days"

  4. Becky says:

    Hi Ablebits, can you help please?
    I have this formula working:
    =DATEDIF(T78,I78,"Y")&"y"&DATEDIF(T78,I78,"YM") &"m"
    where T78 is a date of birth and I78 is a specified date (start of course). It shows me the age of a student in years and months.
    I'm trying to use conditional formatting to highlight where a student is under 18 years of age, but coming unstuck as it doesn't like the "y" and "m" text in the formula.
    Many thanks for any advice.

  5. Becky says:

    That gives a True or False, where I definitely need to see the age in years and months. I'll try something else, thanks for the help though.

    • Hi Becky,

      Your initial request was "use conditional formatting to highlight where a student is under 18 years of age", and it it exactly what the formula does. To put it differently:

      - If you enter the formula in a cell, it returns true / false.

      - If you create a conditional formatting rule based on the above formula, it will highlight students under 18 years of age. If you need the detailed instructions on how to create a formula-based rule, please check out the following tutorial: Excel formulas for conditional formatting

      To see the age in years and months, you can keep using your original formula.

  6. Olivier says:

    Hi ! This blog is very useful ! I use the DATEDIF function to calculate the age of children each month (in column the months for the next 10 years, and in raw the children). Now, I need to use a color for the cell where the child reaches "3 years 0 months 0 days", another color for the where he reaches 4, another color for the cell where he reaches 5... and so on.
    I try to use the conditional function but it doesn't work. I wonder if it is because of the format (X years, X months, X days). The format is in "standard" and I changed to "number" but it doesn't work...
    So 2 questions :
    - how to highlight (or use a specific format) when I use the datedif function ?
    - how to highlight the cell where a child reaches 3 yo but not the other cells where is over 3 ?
    I hope you can help me...

    For removing points i think you can use find & replace formula....

    You can use key (Ctrl + F)

    you have to do the following :-

    1. Select Date
    2. Use Ctrl + F
    3. Find What : . (write dot in this tab)
    4. Replace with : (leave this tab blank)

    and then click "Replace" or for multiple selection you can use "Replace All"

    • Hello Crystal,

      Supposing, the DOF is in column B, and the year of the participation in the program is in column D, you can use the following formula:

      =DATEDIF(B2,DATE(D2, 1, 1),"y")

      Because the exact date of the program is not defined, you can supply the date and month that you think are the most appropriate, like January 1 in the above example: DATE(D2, 1, 1)

      After you entered the date (make sure to enter the complete year - 2040, not just 40), select the cell and press Ctrl+1 to open the Format Cells window. There, go to Date tab and find the following data type: 14-Mar-2012. Select it and press OK.

      Hope it helps!

    Hi All,

    How can I add year fraction in excel. for e.g. I have 1st company experience as 2.6 (2 years 6 months) and next company experience is 16.10 (16 years 10 months) if I am adding both ideally my total experience is 19.4 (19 years 4 months) whereas if I am trying to calculate in excel, outcome is 18.76.

    Please advise if I could use any alternate formula to sum up year fraction in excel.

    Hello experts! I wish to calculate a student's current grade in school based on their graduation year. The trick is that students' grade levels change as of July 1st each year. Examples: A student's graduation year is 2021. Today is May 25, 2018. They are currently in 9th grade, but as of July 1st, 2018 will be in 10th grade. Perhaps it would be useful to assume that "graduation year X" really equals "June 30, year X"?

    Here are the graduation years and corresponding grade levels through June 30th. As of July 1st, the grade level will need to rise by 1.

    2029 - 1
    2028 - 2
    2027 - 3
    2026 - 4
    2025 - 5
    2024 - 6
    2023 - 7
    2022 - 8
    2021 - 9
    2020 - 10
    2019 - 11
    2018 - 12
    >2018 - grad

    Further, could the formula cause the cell to be shaded yellow if the grade is 1-5, green if grade 6-8, blue if grade 9-12, and pink if grad?

    It would also be useful to be able to do the opposite - calculate a grad year based on their current grade in school.

    I know you must enjoy a good puzzle!

    Many thanks.

    How can i add year to date for payroll?

  70. April J Garcia says:

    I was wondering how i can add year to date to an excel sheet gor payroll i have no current year to date on the spreadsheet right now?

    • Doug says:

      I think you're asking how to create a running total. This is where the latest data is added to the existing total to display the most current total. This procedure is repeated each time data is added so that the sheet shows the newest data and the newest total.
      If this is what you want to do, you create a running total by entering a range formula which is part absolute reference and part relative reference. The range formula looks like this: $A$1:A1. Absolute reference with the "$", relative reference without it. Where A1 is the first cell in the range.
      So, if the cell that will hold the payroll to be used in the Year-to-Date amount is in column "D" and the calculated running total is in column "E" the formula in column "E" will look like this:
      =SUM($D$6:D6) formula in E6 displays Year-to-Date of amounts in cells above E6
      =SUM($D$6:D7) formula in E6 displays Year-to-Date of amounts in cells above E7
      =SUM($D$6:D8) formula in E6 displays Year-to-Date of amounts in cells above E8
      After you've copied it down to row 6, 7 & 8. This will calculate the running total to row 8. Just continue to copy this formula down the "E" column to display the most current Year-to-Date.

    Would appreciate if you give provide a formula for below scenario. Thank you in advance.
    Start date: 5-27-2013
    End Date: 10-3-2019
    Counting number of years using a fraction of at least six (6)months being considered as one (1) whole year. So, 5-27-2013 to 12-31-2013, is considered one (1) year. Counting on a yearly basis, it means that from 5-27-2013 to 10-3-2019, is considered 7 years. Can you please provide me a formula for these?

    I have list of employees with their date of birth (in dd-mmm-yyyy format) n a worksheet.
    I want to highlight the date of birth in rows which are unique. ie., just the date & month when they are unique ignoring the year. eg., there may be two employees, 1 with date of birth 2-Jun-1993 & another with date of birth 2-Jun-1975. So, i want these two to be highlighted ignoring the year.
    Can you please help me how to do it either using a formula or conditional formatting.
    Thanks in advance.

  80. Cyril Paul says:

    I'd like to calculate end-dates for financial purposes.

    E.g., a security with a 1 year maturity period will mature on 31/12/2020, if the investment was made on 01/01/2020.

    DATE formulae in Excel that I have seen so far seem to reflect the anniversary of the start date, i.e., 1 year from 01/01/2020 is given as 01/01/2021 (and not 31/12/2020) and 5 years from 01/01/2020 is given as 01/01/2025 (and not 31/12/2024, which is the correct date).

    Is there any way to address this?

    This is bizarre... Is there no way just to enter simple years into an Excel table without converting from something, so that Excel recognizes it as a year??
    I made a simple data table and a line chart with two data sets. But... They came out as separate, consecutive curves, not overlapping. And the years with data were not spread in a time scale in my graph, but regularly, even where I had 100-year gaps. I decided it is, because the cells were formatted as "general". OK, but whatever I tried messed up my year values. I don't have days to start with, only years. I reformatted the cells and re-entered the years, and they change. I. e. I type in 1818, and the cell makes 1904 out out of it (Why??). Same happens if I type the data in first, then reformat to yyyy. If I invent dates before reformatting, all ends up as the same year. This is so wrong. I wouldn't bother with the cell format and leave it at "general", but then Excel doesn't get the distances right between the time periods. Can Excel not do years by themselves???

  84. Christine says:

    Oh, and I cannot invent days to get around this, either, because the program abbreviates both, the 1900s and the 2000s to the last 2 digits, so there is no longer a difference between the two millenia (i.e. 1913 and 2013 both show up only as 13 - Why??). Not so with the 1800, it would still be 1813 - what IS going on??

  85. Christine says:

    It becomes even worse: It doesn't look as if Excel can do dates before 1900? I cannot attach a screen shot here, can I?
