Re: [math-fun] Weeks Between Easters

You're not taking into account "leap seconds", which are necessary to keep midnight at midnight, and the gradual recession of the moon, which is gradually changing the length of the lunar month. For example, over the quoted span of 5 million years, leap seconds at the rate of one a year would result in 57 fewer days between now and then. .. exposing the futility of calculations about dynamic systems over these time scales. You're really doing the equivalent of arguing how many angels can dance on the head of a pin.
