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 :
46
=DATEDIF(C8,TODAY(),"y")
and the months :
8
=DATEDIF(C8,TODAY(),"ym")
and the days :
19
=DATEDIF(C8,TODAY(),"md")
You can put this all together in one calculation, which creates a text version.
Age is 46 Years, 8 Months and 19 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.
