I think this is the pattern to leape years: Any year divisable by 4 is a 
leape year, unless it is divisable by 100 as well, but if it is divisable 
by 400 than it is a leape year.
so 1900 was not a leapyear becaus, altho it was divisable by 4 it was 
also divisable by 100. The year 2000 will be a leapyear because, altho, 
like 1990 it is divisable by both 4 & 100, unlike 1900 it is also 
divisable by 400.
i got this from Apples Software's (www.apple.com) 2k bug info page.
