(10 centuries? Doesn't something special >happen on the years 1000, 2000, 3000, etc.?) I presume this was about the number of different calendars. If so, I disagree. The "year in the leap-year cycle" is not involved except for the leap-year yes/no. A year which is not a leap-year, and starts on, for example, a Wednesday, will have the same calendar no matter whether the next leap-year is 1, 2 or 3 years ahead. It STILL looks like 7 leap-year calendars, 7 non-leap-year calendars, 14 total calendars. As for centuries (for which the definition of leap-century is simple enough), it is still either leap or non-leap, and starts on one of the 7 days! FROM: Brian G.
