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.
