Calculating age

[dunbarx at aol.com]

Hi.


There would be a problem with certain date ranges. Think of thie variation of your script:



on mouseUp
   convert "1/14/1951" from date to seconds
   put it into dateone
   convert "1/14/1956"  from date to seconds
      put it into datetwo


put datetwo - dateone into age -- calculate the age in seconds
-- divide by the number of seconds per year
put 60*60*24*365.25 into secs_per_year
answer trunc(age / secs_per_year) 


end mouseUp


Its the leap years. You claculate seconds, (and even do the 365.25 thing) but that value may not "close" a leap year if it falls in the wrong place.

Hi, does anyone know how to calculate someones age in years from two dates?

Currently I am doing something kludgy like:

convert dateone from date to seconds
convert datetwo from date to seconds
put datetwo - dateone into age -- calculate the age in seconds
-- divide by the number of seconds per year
put 60*60*24*365.25 into secs_per_year
put the trunc of (age / secs_per_year) into age

But I suspect it is only approximate.

Thanks
