The Gregorian calendar actually does contain rules for calculating the exact date of easter. The official full moon dates repeat in a cycle of 19 years. Every time a leap year is skipped, the dates are moved one day to compensate. Since the 19 year cycle is not exact, the dates are moved one day every 300 years. Once every 2500 years, the period between adjustments is 400 years in stead of 300, giving a cycle of 2500 years. The dates were moved in 1700 and in 1800. In 1900 a leap year was skipped, but it was 300 years since the system was started, and the two adjustments canceled out. In 2000 the leap year was not skipped, so no adjustment.
This does not mean that the date of easter repeats in a cycle of 2500 years, only that the official date of the full moon does. Easter is the first sunday after the first full moon after the vernal equinox. How long the cycle is for this I don't know, and it is moot anyway since the system is not going to be in use for that long.

I made a mistake here. It is of course not the predicted date of the full moon that repeats every 2500 years, it is only the pattern of adjustments of that date. The cycle for the date itself is much longer. And the cycle for the date of easter most likley seven times that.
