I'm no authority, but I swear my college astronomy book says: Gregorian calendar established %4 = leap %100 = not %400 = leap and it also says the Russians added: %4000 = not but this is not part of the standard Gregorian definition. There's some more calendar info at: http://astro.nmsu.edu/~lhuber/leaphist.html and http://www.calendarzone.com Phil Brady _________________________________________________________________ Unsubscribe & list info -- http://www.scruz.net/~luke/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers
