Hmm. I thought it was because the tax was paid in kind, and the change meant that they were due before the harvest was done. But it seems that we're all wrong: the riots probably never happened. The normal taxes weren't affected. Before the change, the tax year ended on Lady Day (25 March), but this was changed to 5 April, still the case today. And interestingly, it seems that before the change the calendar year also changed on Lady Day, so 24 March 1750 was followed by 25 March 1751. This, too, was changed.

We can't agree on the age difference. The other reference, of course, is Gilbert and Sullivan's "The Pirates of Penzance", where Frederic, the hero, was born on 29 February 1860 and apprenticed to a band of pirates until his 21st birthday (a paradox: 29 February 1940).

Other countries changed at other times - Russia as late as 1918. The funniest transition was done by Sweden, though. They decided to transition over a period of forty years, by skipping leap days. They dropped the leap day in 1700, then forgot to do it in 1704 and 1708, gave up and went back to the Julian calendar in 1711, and stayed with that until 1753, when February 17th was followed by March 1st. -tih -- Most people who graduate with CS degrees don't understand the significance of Lisp.

Given that the source: https://minnie.tuhs.org//cgi-bin/utree.pl?file=V6/usr/source/s1/cal.c has been in C since at least V6, I'd be rather surprised if on other machines it did anything other than what those of us who were paying attention read in the documentation: https://minnie.tuhs.org//cgi-bin/utree.pl?file=V6/usr/man/man6/cal.6 back then: "Try September 1752." Get off my lawn. Noel PS: Said documentation already notes that it won't work in most counries: "The calendar produced is that for England and her colonies."

It's even more funny than that :-) They actually went back to the Julian calendar in 1712, and they needed to add back the leap day they skipped in 1700; this extra day became February 30th. https://en.wikipedia.org/wiki/List_of_non-standard_dates#February_30 Tony. -- f.anthony.n.finch <dot@dotat.at> https://dotat.at/ Great Orme Head to the Mull of Galloway: East or southeast, becoming cyclonic, 3 to 5, then variable 3 or less later.
