We need totals of clients by age bracket. What is the best way to calculate the age? Right now, we are using:

INT((DATE() - a.dob) / 365)

But that doesn't take into consideration leap years (which could be significant for someone over 90 years old). Any suggestions? Should I just use:

INT((DATE() - a.dob) / 365.25)

Or is there a better (more accurate) way?

Thanks,
Doug
