- OK: You're utterly blind to the way our adopted calendar has worked for centuries.
- It isn't just a matter of checking divisibility by 4 - there are at least
- 3 orders of correction, and I thought there were 4.
-
- Until yesterday, I believed the complete rule was
-
- If the year is divisble by 4, it's a leap year,
- unless it's divisible by 100, in which case it isn't,
- unless it's divisible by 400, in which case it is,
- unless it's divisible by 2000, in which case it isn't
- unless it's divisible by 26000, in which case it is.
-

- But according to a colleague who checked the Encyclopeadia Britannica, the rule is
-
- If the year is divisble by 4, it's a leap year,
- unless it's divisible by 100, in which case it isn't,
- unless it's divisible by 400, in which case it is,
- unless it's divisible by 4000, in which case it isn't.

- I really need to know the complete rule: I'm planning a party for
- 29 February 26000, and it may be too late to change the invitations.
