by 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, WEEKNUM, MONTH, and DAY. 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 in Excel returns a four-digit year corresponding to a given 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.
Excel YEAR formula
To make a YEAR formula in Excel, you can supply the source date in several ways.
Using the DATE function
The most reliable way to supply a date in Excel is using the DATE function.
For example, the following formula returns the year for 28 April, 2015:
=YEAR(DATE(2015, 4, 28))
As a serial number representing the date
In the internal Excel system, dates are stored as serial numbers beginning with 1 January 1900, which is stored as number 1. 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:
=YEAR(42122)
Though acceptable, this method is not recommended because date numbering may vary across different systems.
As a cell reference
Assuming you have a valid date in some cell, you can simply refer to that cell. For example:
=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:
=YEAR(TODAY())
As text
In a simple case, the YEAR formula can even understand dates entered as text, like this:
=YEAR("28-Apr-2015")
When using this method, please double check that you enter the date in the format that Excel understands. Also, please remember that 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:
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")
Or
=TEXT(B2, "mmm") & "-" & TEXT(B2, "yy")
Where B2 is a cell containing a date.
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.
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 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:
Where DOB is the date of birth.
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:
=INT((TODAY()-B2)/365)
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")
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:
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.
How to get the day number of the year (1-365)
This example demonstrates how you can get the number of a certain day in a year, between 1 and 365 (1-366 in leap years) with January 1 considered day 1.
For this, use the YEAR function together with DATE in this way:
=A2-DATE(YEAR(A2), 1, 0)
Where A2 is a cell containing the date.
And now, let's see what the formula actually does. The YEAR function retrieves the year of the date in cell A2, and passes it to the DATE(year, month, day) function, which returns the sequential number that represents a certain date.
So, in our formula, year is extracted from the original date (A2), month is 1 (January) and day is 0. In fact, a zero day forces Excel to return December 31 of the previous year, because we want January 1 to be treated as the 1st day. And then, you subtract the serial number returned by the DATE formula from the original date (which is also stored as a serial number in Excel) and the difference is the day of the year you are looking for. For example, January 5, 2015 is stored as 42009 and December 31, 2014 is 42004, so 42009 - 42004 = 5.
If the concept of day 0 does not seem right to you, you can use the following formula instead:
=A2-DATE(YEAR(A2), 1, 1)+1
How to calculate the number of days remaining in the year
To compute the number of days remaining in the year, we are going to use the DATE and YEAR functions again. The formula is based on the same approach as Example 3 above, so you are unlikely to have any difficulties with understanding its logic:
=DATE(YEAR(A2),12,31)-A2
If you want to know how many days remain till the end of the year based on the current date, you use the Excel TODAY() function, as follows:
=DATE(2015, 12, 31)-TODAY()
Where 2015 is the current year.
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:
=DAY(DATE(2015,3,1)-1)=29
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:
=DAY(DATE(YEAR(A2),3,1)-1)=29
Where A2 is a cell containing the date.
The results returned by the formula are as follows:
Alternatively, you can use the EOMONTH function to return the last day in February, and compare that number with 29:
=DAY(EOMONTH(DATE(YEAR(A2),2,1),0))=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")
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")
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?
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.

Hi, for some reason I cannot change the date into year. i use the formula =YEAR and the corresponding cell, but it doesn't work.
Hi! Your date may have been written as text. Try to use the recommendations described in this article: How to convert text to date in Excel.
How do you convert this cell date from "94-01" to show "1994-2001" in excel?
Hi! "94-01" is a text string, and you cannot convert it into a date string. However, you can use the LEFT and RIGHT functions to extract the numbers of the year from the text. You can then use these numbers and the DATE function to create dates, and then extract the year from the dates using the YEAR function. Use the & operator to combine these years into a text string.
Try the following formula:
=YEAR(DATE(LEFT(A1,2),1,1))&"-"&YEAR(DATE("20"&RIGHT(A1,2),1,1))
Thanks, for 06-13 it returned 1906-2013, how do I edit the formula so that it distinguishes 1900's from 2000's?
Hi! Use the IF function to compare the two numbers written in your text string. If the first number is less than the second number, do the calculations for 1900's.
=IF(--RIGHT(A1,2)<--LEFT(A1,2), YEAR(DATE(LEFT(A1,2),1,1))&"-"&YEAR(DATE("20"&RIGHT(A1,2),1,1)), YEAR(DATE(LEFT(A1,2),1,1))&"-"&YEAR(DATE(RIGHT(A1,2),1,1)))
Hello,
Thank you for your great blog. Maybe you can help me figure this out. I've used this formula:
=DATEDIF(0,A10,"y")&" years " &DATEDIF(0,A10,"ym")&" months "&DATEDIF(0,A10,"md")&" days" which delivers the correct information. I'd like to tweak it a bit so that if the contents of cell A10 is 23, the result won't be "0 years 0 months 23 days" but simply "23 days". Same for months and years. No need to show 0. Also, is there a way to get rid of the plurals, e.g. "1 year 1 month 1 day" instead of "1 years 1 months 1 days"? Thank you for your efforts.
Hi! To show only positive numbers if years, use the IF function. Change the text after the number of years in the formula if necessary. For example:
=IF(DATEDIF(0,A10,"y")>0,DATEDIF(0,A10,"y")&" years ","") &DATEDIF(0,A10,"ym")&" months "&DATEDIF(0,A10,"md")&" days"
Eg. I need formula that the text function for 26th January 2023 to 25th February 2023 , result is February 2023.
What function should I use ?
See answer in this comment on our blog.
I also want to know?
Hii, I just want to check that if I am putting date as 01 Jan 2020 and I have to add the 3 years and I want the answer has 31 Dec 2023 please provide formula to calculate
Hi! Look for the example formulas here: How to add and subtract dates in Excel.
Is it possible to format a year (just the number) as a date? I tried using the yyyy, but it calculates a specific date. For instance, the cell has the year 2003, if I format it using the yyyy, it will show the stored date 6/25/1905. I need it for a csv file to create a dashboard and have the key date. Thank you!
Hi!
If the cell contains only the year 2003, then this is a number, not a date. You can convert a year number to a date using the DATE function.
For example,
DATE(2003,1,1) or DATE(A1,1,1)
Suppose you have a date in a cell (A1): 3/14/2020 and in another cell (A2) you need to return 12/31/2032 the end of year date 10 years from A1. I have the formula for to get the 10 years from now, but can't figure out how to get the 12/31 aspect of it without saying the month differential which I prefer to avoid because A1 date is not a constant.
Edit: A2 should return 12/31/2030... not 12/31/2032
Hello!
To determine the last day of the year, use the DATE function.
=DATE(YEAR(A1)+10,12,31)
Here is the article that may be helpful to you: How to add and subtract dates, days, weeks, months and years in Excel.
Thank you!
7 years,11 months, 24 days Is given value in a1. I want to use if formula with if a1>20,12,24. How to use the tool. Kindly guide
Hi!
Extract 3 numbers from a text string using these guidelines - Extract number from text string. Then compare them with the desired values using the IF formula with multiple statements.
Hi,
I'm working on a spreadsheet which contains data for 2020, however halfway through the spresdsheet excel has changed the year to 2021, Can this be fixed apart from manually going through the spreadshet and updating each date maunally?
Hello!
You can add a year to 2020 dates in a separate column. Then copy these results into your original date column.
=IF(YEAR(A1)=2020,DATE(2021,MONTH(A1),DAY(A1)),A1)
Use this guide: Subtract dates in Excel; add days, weeks, months or years to date.
I want to make a sheet for employees leave calculation. So in that if the employee joining date last year 19 december 2021 in one column i need to bring same day and month but current year how can i do it.
Hi!
To get the desired date, use the DATE function. Determine the current year using the YEAR and TODAY() functions:
=DATE(YEAR(TODAY()),MONTH(A1),DAY(A1))
how to split this 06/03/1971 (50 years old ) to this 06/03/1971 only with fuction??
Hello!
You can find the examples and detailed instructions here: How to split text in Excel using formulas.
=LEFT(A2,SEARCH(" ",A2,1))
This should solve your task.
How can i sort in ascending order in this format 0 years, 0 months, 29 days?
Hello!
Your data is text. For correct sorting, I recommend that you write down all numbers with two digits. For example
01 years, 05 months, 09 days
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?
Hi Christine,
You are right - Excel does not recognize dates before 1900. In the internal Excel system dates are stored as serial numbers beginning with January 1, 1900, which is stored as 1.
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??
Hi,
To display the year in four digits, use the "yyyy" format. If you only want the year in the date, write the date as 01-01-1913.
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???
Hello!
If I understood the problem correctly, you want to work with dates before 1900. Unfortunately, Excel only works with dates after January 1, 1900.
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.
Hello!
I recommend using an extra column. Write down the dates of birth with the same year in it. You can use something like this:
=DATE(2000,MONTH(A1),DAY(A1))
In this column use conditional formatting - Highlight cell rules - Duplicate Values
I only have a data of year and number of day in a year. Example Year is 2020 and the number of day in the year is 32 then the result should be Feb 2, 2020. Is there a formula which I can obtain this result?
Correction: the result should be Feb 1, 2020
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?
April:
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.
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.
Regards,
Vikram
Hello,
Please try the following formula:
=(2+16+TRUNC((6+10)/12)) &" years " & ((6+10)-(12*TRUNC((6+10)/12))) & " months"
Hope it will help you.
What is the formula I should use when trying to find the total number of entries for a specific year? See Below:

I am trying to figure out how many people were "rejected" in 2013, 2014, 2015, etc. without having to create numerous columns, etc.
Thank you for your help.
Hi, Megan,
if you have an additional status column saying who was rejected, you can use COUNTIFS function. Please read this article to learn more about the COUNTIFS syntax and to be able to use it.
