2000 is a leap year. A regular one. On the Gregorian calendar, 1700, 1800, 1900, 2100, 2200 and 2300 are not leap years, but 1600, 2000, and 2400 are. Note that when a certain jurisdiction switched to the Gregorian calendar is, at one level, irrelevant -- it is perfectly legitimate to refer to the year 400 on the Gregorian calendar being a leap year, despite the fact that the Gregorian calendar was invented in the 16th Century AD.
