Age Calculation 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 :	1-Jan-60
Years lived :	50	=DATEDIF(C8,TODAY(),"y")
and the months :	4	=DATEDIF(C8,TODAY(),"ym")
and the days :	15	=DATEDIF(C8,TODAY(),"md")
You can put this all together in one calculation, which creates a text version.
Age is 50 Years, 4 Months and 15 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 :	1-Jan-60
Age is :	50.37	=(TODAY()-C23)/365.25
