Even tho' Pope Gregory (I forget which number) directed that the calendar be changed in 1582, the Protestant countries did not follow suit until much later. Did you know that George Washington was born on Feb. 11? He changed his birthday to Feb. 22 when the colonies adopted the new calendar, early in his lifetime. That would place the change sometime in the 1720-1740 time frame. Notice that by then the discrepancy was 11 days, instead of 10. I think this is because of the 1600 (not) leap year business. BTW, does anybody know definitively whether 2000 will be a leap year? I get confused: centuries, e.g. 1900, aren't leap years, but multiples of 400 ARE leap years, and then someone raised the question about multiples of 2000. So at this point, I just don't know. 2000 is close enough that we should probably start planning, checking date algorithms, and so forth.
