Great! Actually, the other way it is likely to be wrong is when
today's date is very close to the persons birthday - eg if a persons
age is really 16 yrs 11 months, and their birthday is a couple of
days from now, it may give 17 yrs 0 months.
These date/period things can be tricky, so you have to decide how
accurate you need to be, and do the extra work to accomodate that!

Thanks Mark,
It works!
Like I said it's an educational stack so the pupils/students are not
older than 20 so leap years are not important.

2006/9/8, Mark Smith <[EMAIL PROTECTED]>:
function getAge bDay
put 60 * 60 * 24 * 365 into secsPerYear
put secsPerYear / 12 into secsPerMonth
put the seconds into tDay
-- assuming date of birth is given in short system date format
convert bDay from short system date to seconds
put tDay - bDay into tAgeInSecs
put tAgeInSecs div secsPerYear into tYears
put (tAgeInSecs mod secsPerYear) div secsPerMonth into tMonths
return tYears && tMonths
end getAge
This is pretty rough and ready, it doesn't try to take into account
leap years and so-on, but unless the person is really old (100 yrs
+ ?), it should be close enough. Also, see 'centuryCutoff' in the
docs if you're going to be dealing with older people.
Best,
Mark
