Subject:      Re: compute # of weeks & years from date variables
Content-Type: text/plain; charset=us-ascii

* Weeks:.
Compute week1 = CTIME.DAYS(date2-date1)/7.
Compute week2 = CTIME.HOURS(date2-date1)*168.
Compute week3 = CTIME.MINUTES(date2-date1)*10080.
 
* Years:.
Compute Years = CTIME.DAYS(date2-date1)/365.25.
 
The question might be is there a "simple" function to do this?
Answer : No.
 
After reflection and before hitting send button :)
Maybe the question is years and weeks? Like an age in years and weeks ?
 
* the sequence returns two variables number of years and remainder
weeks:*.
Compute Weeks=Ctime.Days(date2-date1)/7.
Compute Years=Trunc(Weeks/52).
Compute Weeks=Mod(Weeks,52).
