date calculation

[DeMichele, Matthew]

I have two date variables arranged as YYYYMM and YYYYYMMDD. The first
variable is date of birth and the second is date of admission to
treatment. I am trying to calculate age_at_admission, but am running
into trouble. Is this a possible calculation since SPSS calculates dates
as seconds since 10, 14, 1582?

Thank you for your help.

in the various documentation and help system.  There is also the DATETIME wizard which I have never bothered to use but might be useful if you are not literate in the various underlying syntax.
