You can use the xdate functions - xdate.year, xdate.month, xdate.mday or xdate.year, xdate.jday in COMPUTE to take apart a date value, manipulate these as needed, and convert back to a date value with the date.yrday and related functions.

SPSS stores dates as seconds elapsed since 00:00:00 on 14 Oct 1582.

Try adding 31,536,000 (the number of seconds in a 365 day year)

Good luck

I'm having trouble and need some help.

I have a date variable that I would like to have SPSS add 365 days to it and give me another date variable xxxx. Can someone help?
