Since you only need straight years, subtract the birth year from the current date then a simple switch statement to adjust for whether the birthdate has been met for the year should work fine. Something like:
switch case check to see if the month now < month of the birthdate if so, subtract 1 from tYears break case if the month now = the month of the birthdate tBdate) and the day now < the day of the birthdate if so, subtract 1 from tYears break end switch Also, curious now. Can you convert dates to seconds if they're before the epoch? Its not working for me in 6.6.2. Anything after 1970 works fine.
