Method A: Convert birthdate to age with subtraction
Normally we figure out someone's age with current date subtracting the given birth date. So does it in Excel.
Step 1: Enter current date in a blank cell, such as 2016/4/7 in Cell B2.
Step 2: In another blank cell (says cell C2), enter the formula =INT((B2-A2)/365), and press the Enter key.
Method B: Convert birthdate to age with DATEDIF function
Some would like to apply the DATEDIF function to calculate the age. Enter the formula =DATEDIF(A2,NOW(),"y") in a blank cell, it calculates the age immediately after pressing the Enter key.
Method C: Convert birthdate to age with ROUNDDOWN function
Another function to convert the birth date to age is =ROUNDDOWN(YEARFRAC(A2, TODAY(), 1), 0), which will figure out a standard age, such as 27.
Method D: Convert birthdate to exact age with DATEDIF function
Sometimes exact age is requires, and you may want to know how many years, months, and days from the birth date to current date. The following formula can help you figure out:
=DATEDIF(A2,TODAY(),"Y") & " Years, " & DATEDIF(A2,TODAY(),"YM") & " Months, " & DATEDIF(A2,TODAY(),"MD") & " Days"
See the screen shot above, this formula will show you precise result, such as 23 Years, 8 Months, and 14 Days.

for the whole-hearted appreciation of my solution!
To post as a guest, your comment is unpublished.· 7 months agoI have used the following to calculate the age of children in my class.
with B4 being their date of birth. It produces the correct answer (eg) 9.11
They take tests 3 months later so I need in another cell to calculate '+3' months. But each time I do this I get 9.14 when I need it to say 10.2
Can anyone help.
To post as a guest, your comment is unpublished.· 6 months agoYOU ARE AMAZING!!! It worked fantastically. I can now convert all the data for tests from the children in my class using this and I don;t have to work out their age each time. This makes my job much quicker and easier.
To post as a guest, your comment is unpublished.· 6 months agoUnclear my post went through or not, in response to Catherine's query.
Repeat my formula which finds the difference between cell B4 contents and a date TODAY() advanced by 3 months:
To post as a guest, your comment is unpublished.· 6 months agoThe DATEDIF formula used to give the Years and Months in a YY.MM format is understandable. However, each of the 2 components of this formula is a separate number, integer. So, adding 3 to the MM part will only give 14 if it is 11 before the addition. The formula does not know you are looking to set it up as a MONTH.
So, if you get the DATEDIF between B4, and a date which is a valid date but 3 months after TODAY(), try the following formula, works for me and gave 10.2:
Please confirm it worked for you.
