2/29    Why is this year being a leap year such a big problem?  If a computer
        wasn't designed to recognize the 4/100/400 rule, it'll take the simple
        rule that every 1 out of 4 years is a leap year and will still treat
        Year 2000 as a leap year.  No one was going to think 4/100 but not
        4/100/400, right?  -- yuen
        \_ Never attribute to malice...
        \_ Wrong.  People do stupid things and that was one of them.
        \_ 4/100 is more commonly known than 4/100/400.  Also 4/100/400 takes
           some tiny shred of thought to remember and code.  Thus lots of folks
           such as SGI and Microsoft blew it.
                \_ Wasn't it that some programmers thought that the rule
                        was that every 400 years, February has 30 days.
                        \_ Uh yeah, uh huh, sure, yuppers.
                        \_ Actually, you're right on this.  I originally
                           learned about the 400 rule from somebody that
                           thought February would have 30 days in 2000.  She
                           didn't know about 100's not having a leap year.
