Calculating Age from DOB

[roday]

I'm trying to set up a calculated column that will give me "Age" using the difference between the dates "Today" and a date of birth. When I calculate this value, the result is in a timespan (i.e 6570.00:00:00). I'm trying to get this to convert to years but haven't had any luck. Everything I try seems to break the report. Any advice is greatly appreciated!

Hello.

We are using standard .Net Framework TimeSpan type.
Here is a description of custom format string.

Thank you.
