i've just worked it out when easter will be next year, and it will be even earlier - sunday 23rd March i wouldn't bet on the weather at that time of year, and would choose a time later on. problem is, you rarely get 4 full days in a row of tourist drives, especially on bank holidays, so you have to take a lot of time off.

The usual statement, that Easter Day is the first Sunday after the full moon that occurs next after the vernal equinox, is not a precise statement of the actual ecclesiastical rules. The full moon involved is not the astronomical Full Moon but an ecclesiastical moon (determined from tables) that keeps, more or less, in step with the astronomical Moon.

The ecclesiastical rules are:

Easter falls on the first Sunday following the first ecclesiastical full moon that occurs on or after the day of the vernal equinox;

this particular ecclesiastical full moon is the 14th day of a tabular lunation (new moon);

and the vernal equinox is fixed as March 21.
