Re: How to calculate end of the month.

I suggest you should use the date and time wizard. It is found under compute. If you have a date variable you should be able to extract that day with any type of referential.

Still with SPSS date variables -

First, go *12* months out, instead of 11. That's not because 12 months
is a year; it's because 12 months is one more than you want:

*** month and year, adjusted for change of year (month gt 12).
COMPUTE month_12 =xdate.month(date)+12.
COMPUTE year_12 = xdate.year(date).
if month_12 GT 12 year_12 = year_12+1.
IF month_12 gt 12 month_12 = month_12-12.

(Of course, for exactly 12, the logic is easier, but I'm leaving it
general.)

Second, the 'cute' part: the last day of the month 11 months out, is
the day before the first day of the month 12 months out:

COMPUTE end_date = date.mdy(month_12,1,year_12)-TIME.DAYS(1).
