|
| 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!) |

|
| Years lived : | 49 | =DATEDIF(C8,TODAY(),"y") |
|
|
|
| and the months : | 11 | =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 49 Years, 11 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. |
