    SubjectRe: [OFFTOPIC] Y2k compliance
    In regard to the discussion about those special years...

    Here is what i found from the net;

    Regarding year 2000

    "Firstly, here is the rule. A year is a leap year (and so contains a
    February 29) if it is divisible by 4. But if the year is also divisible
    by 100 then it is not a leap
    year, unless it is divisible by 400. This means that years such as 1992,
    1996 are leap years because they are divisible by 4 and are not affected
    by the rest of
    the rule which applies to century years such as 1900 and 2000. Century
    years are not leap years except where they are a multiple of 400. Hence,
    the years
    1700, 1800 and 1900 were not leap years and did not contain a February
    29. But the year 2000 will be a leap year, the first such century leap
    year since
    1600. "


    Regarding; "/usr/bin/cal 9 1752"

    "The Julian calendar is named after Julius Caesar, and between its
    introduction in Roman times and the middle ages in Europe there was an
    appreciable drift
    in the seasons. This forced a reform of the calendar by Pope Gregory in
    1582, with 10 days were left out of October of that year (with some
    anguish) to
    bring the seasons back in phase. It took some time for this system to be
    introduced in Britain from Europe and this did not occur until 1752.
    Imagine the
    confusion of not only a time change when travelling but also a different
    date. "

    &gt;Yes, if my memory serves me right (I'm too old I guess - shh, don't tell
