Is there a way to calculate age in years, months & days?

I think just from the assumptions of 365 days in a year, and 30 days in a month - you'll get some variance of a few days (depending on which months you count as 28, 29, 30, 31 days, etc.).

i.e. If you say the age is 10 years, 6 months, 3 days - which 6 months you are talking about would affect the ages by a few days either way.  

If you can describe an alternate method of calculating the age in years / months / days that would match what you want, we can look at translating that into QuickBase formulas.
