How to calculate age in excel.

You can calculate a persons age based on their birthday and todays date.

The calculation uses the DATEDIF() function.

The DATEDIF() is not documented in Excel 5, 7 or 97, but it is in 2000.

(Makes you wonder what else Microsoft forgot to tell us!)

Birth date :29-Apr-73

 

Years lived : 38  =DATEDIF(C8,TODAY(),"y")
and the months : 9 =DATEDIF(C8,TODAY(),"ym")
and the days :     7 =DATEDIF(C8,TODAY(),"md")

 

 

You can put this all together in one calculation, which creates a text version.
Age is 38 Years, 9 Months and 7 Days
 ="Age is "&DATEDIF(C8,TODAY(),"y")&" Years, "&DATEDIF(C8,TODAY(),"ym")&" Months and "&DATEDIF(C8,TODAY(),"md")&" Days"

Another way to calculate age
 
 
 
 
 
This method gives you an age which may potentially have decimal places representing the months.
If the age is 20.5, the .5 represents 6 months.

Birth date : 01-Jan-60
Age is : 52.10                 
 =(TODAY()-C23)/365.25
