Age Calculation
- 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.
| Birth date : | 29-Apr-73 |
| Years lived : | 46 |
| and the months : | 8 |
| and the days : | 19 |
=DATEDIF(C8,TODAY(),”y”)
=DATEDIF(C8,TODAY(),”ym”)
=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.
| Birth date : | 01-Jan-60 |
| Age is : | 60.04 |
=(TODAY()-C23)/365.25
