Leap year doesn't matter.

SAS knows which years are leap years, at least through 19999 the last time looked, and 'e' option in intnx takes that into account.

Yes I said 19999. I had to demonstrate this multiple times during Y2K worries about the data I was storing in SAS. The date formats don't display properly because of the 5-digit year but the date functions work just fine.
