Art Bahrs asks:
Isn't there Leap Century and Leap Millennium????
See if I remember this correctly. I've done lots of date calculation stuff in my
'actuarial' days, but I'm getting foggy in my old age ...
Leap years are those dates that are evenly divisible by 4, except that
centuries must also be divisible by 400. So, 1900 wasn't a leap year
even though evenly divisible by 4, but 2000 is.
Yeah, that's the ticket!
