May I recommend David Ewart Duncan's 'The Calendar' recently published by 4th Estate for an interesting insight into the calculation of the year etc. Paul Murphy I'll second that; it was a very good read.

Act of 1752
One of the things about the Act of 1752 which bothered me for a long time was Why did we only lose 11 days The Julian calendar started in 45BC, so there were 1752+45=1797 years (there is no year 0) The Julian calendar is 11mins 14 seconds out = 1 day every 128 years 1797/128=14.03 days So why did we only lose 11 days? I can reveal the answer, for all those out there who, like me, have spent time worrying about this. The spring equinox was not on 21st March in 45 BC, but it had moved to 21st March by the time of the Council of Nicea in 325 AD. This was when Emperor Constantine - the first Christian Emperor of Rome - established, among other things, the rules for Easter (and there's another story). By the time that the Gregorian calendar was introduced in 1582 - and the driving force was to keep the date of Easter correct - the calendar had shifted by:- 1582-325=1257 1257/128=9.82 years So there was a 10 day adjustment. In 1752, we (UK and America) altered our calendar to keep us in line with the rest of Europe, a phrase that still seems to have a certain ring of familiarity. So now you can sleeep easy in your beds.

Yes, this agrees with what I said about 1800 being treated as a normal year in England as a result of her adoption the Gregorian reform. Would England have adopted the Gregorian calendar right from the start in 1582 then 1600 would have been the first centennial leap year. Regardless of adoption of the Gregorian change 1600 would have been a leap year--under both the Julian and Gregorian rules 1600 is a leap year (as is 2000, which is what began this thread of discussion). The first century non-leap year for early adopters of the reform was 1700. However, 1700 was treated as a leap year in England and other late adopters. That is the reason England had one more day of adjustment when the reform was finally adopted. Did you know that by the same act of Parliament in 1751 the start of the year was changed from 25 March to 1 Januari, commencing in 1752 ? Yes.

RE: Act of 1752
No offence taken. Another result of the adoption of the Gregorian Calendar is the loss of 10 days. People's birthdays were recomputed, which is why Washington's Birthday is celebrated on 22 February, despite the fact that he was actually born on 11 February.
