• every 4th year (divisible by 4) is a leap year.
• except that every 100th year is NOT a leap year.
• except that every 400th year IS a leap year.
• except that every 1000th year is NOT a leap year.**

I think you probably meant every 4000th year in that last bullet, right?

But does anyone have any reference to any calendar that officially uses that convention?

**P.S. regarding the English “calendar riots”, my understanding is that they were quite justifiable, given the way this law (like most laws?) screwed over the poor people.

Most english workers of that time were hired by the day, and so they were paid only for the actual days they worked during that shortened month. But they were also renters, and were required to pay a full months’ rent for the month of September, which was in fact only 19 days.

So the landlords got a full months’ rent, while the workers took a nearly 40% pay cut for the month.**

As Poole’s article explains in some detail, that was not what happened. The 1751 Act had anticipated this problem and included specific provisions to protect the rights of tenants. Clause VI of the Act made it clear that ‘nothing in this present Act contained shall extend, or be construed to extend, to accelerate or anticipate the Time of Payment of any Rent or Rents, Annuity or Annuities, or Sum or Sums of Money whatsoever…’. Part of Poole’s point is that as this was therefore not an actual grievance, it is unlikely to have been the cause of any riots.

**(1) The logic is that every fourth year is a leap year, EXCEPT century years, EXCEPT century years divisible by 400. Thus, 2000 is the exception to the exception, which is the way I was taking it.

Oh, no! Is this the exception that proves the rule?
