**Please Note: **
This article is written for users of the following Microsoft Excel versions: 2007, 2010, and 2013. If you are using an earlier version (Excel 2003 or earlier), *this tip may not work for you*. For a version of this tip written specifically for earlier versions of Excel, click here: Ages in Years and Months.

Many times in early childhood education, a child's age in Years.Months format is needed for reporting, admitting, and evaluation. Basically, this format shows the number of elapsed years and months since birth, separated by a period.

There are several ways you can go about getting the desired age. The formula you choose to do the work depends, quite literally, on your preference in formulas.

Assuming that you have the birth date in cell A1, you might think you could use some math on the date to determine the proper information. For instance, you might think that you could use this formula:

=NOW() - A1

This produces a value that is the difference between the two dates, but if you then apply a custom format ("yy.mm") to the result, you'll find out that it doesn't give the sought-after Years.Months. You get something close; the years are right, but the months vary from 1 to 12 when they should vary from 0 to 11. (Somebody can be 12 years and 0 months old, but it is not proper to say 12 years and 12 months old.)

This means that you need to start casting about for a formulaic approach. A simple formula would be the following:

=YEAR(NOW())-YEAR(A1) & "." & MONTH(NOW())-MONTH(A1)

There are many variations on the above, but the problem is that they all only look at the month of today compared to the month of the birthdate; they don't take the day of the month into account. What is that important? Because the number of elapsed months since birth is dependent on how the day of the birth month compares to the day of the present month, and the formula doesn't allow for that distinction.

So, you might consider a more complex formula that actually tries to calculate elapsed years and months, such as the following one:

=TEXT(INT((NOW() - A1)/365.25),"##0")&"."&TEXT(INT(MOD(NOW - A1,365.25)/31),"00")

This comes much closer to what is needed, but it is still possible to be off by a day or two right around the time of the month when the birth day is approached. Closer still is a formula which uses the YEARFRAC function:

=ROUNDDOWN(YEARFRAC(A1,TODAY()),0)&"."&ROUNDDOWN((YEARFRAC(A1,TODAY())-ROUNDDOWN(YEARFRAC(A1,TODAY()),0))*12,0)

The best (and simplest) formulaic approach, however, is this one:

=DATEDIF(A1,NOW(),"y") & "." & DATEDIF(A1,NOW(),"ym")

The formula relies on the DATEDIF function, which determines the difference between two dates. The value returned by the function depends on the third parameter passed to the function. In this case, the first invocation of DATEDIF returns the number of elapsed years and the second returns the number of elapsed months. It provides the most accurate results of any of the formulas discussed so far.

How do you sort the ages in chronological order and not like:

86

83

8

72

7

66

65

64

6

54

Need a little help if possible please.

K3 contains a text entry, in this case '12.0', B3 is their DoB and I3 is another date. The below seems to work in most cases but if, if this case, you have the trailing zero, it doesn't calculate correctly, any suggestions please?!

=K3-(DATEDIF(B3,I3,"y")&"."&DATEDIF(B3,I3,"ym"))

Thanks.

Could you help me figure something out?

I need to determine what age a child was on a given date in the past.

I have all the DOB in column A and need to know what age they are NOW (have figured that out using your formula)

AND

I also need to know what age they were 10 months ago (at the start of February).

While it is easy to do this manually for a few children, when it gets to hundreds I'd like to know how to do this in excel.

Thank you so much in advance....

The months are in a column with today as 0 and each next cell as +1 of the cell above.However, that column does not give me the age till my assets will last and I have to do a side calculation.

So if my age today is 60 years, 0 month, what formula do I use to calculate the next cell in the column to give me 50 years, 1 month, 50 years 2 months and so on and so forth?

Returns XX Yrs XX Months rather than

XX.XX.

Note that reference to E56 below is the cell where you have put the birth date.

=DATEDIF(E56,NOW(),"y") & " Yrs " & DATEDIF(E56,NOW(),"ym") &" Mths"

2016-02-15 18:08:33

Peter Atherton

=DATEDIF(A1,NOW(),"y") & "." & DATEDIF(A1,NOW(),"ym")

"y" Calculates the years between Start date and end date. Everything else is ignored

"ym" calculates the months between the dates and ignores years.

So Birth date = 29th Dec 1929 and now =

86 years + i Month

The above formula shows this as 86.1

Then, in cell B1, put the date you mentioned (August 30, 2014).

Let's say I have the birth date of a child.

I want to work out how old they are on 30th August, 2014 and likewise on 30th August, 2015.

How would I go about doing this?

Thanks Allen! It's been a big help.

While cell A1 has the start date and cell A2 has the end date - try:

=DATEDIF(start_date,end_date,"m")

HI how do I amend this formula so the end result is fully in months eg

24/02/2013 = 24mths.

????

Thanks for sharing knowledge.

You also asked, if I understand correctly, about using a formula with a partial year designation. You could manipulate your formula to add 19,000,000 to it, so that 980101 becomes 19980101.

I hope this helps, but comment again if I misunderstood your questions.

The pair of () are missing from the second NOW.

The formula should look like:

=TEXT(INT((NOW()-A1)/365.25),"##0")&"."&TEXT(INT(MOD(NOW()-A1,365.25)/31),"00")
