This web page contains the frequency of occurrence of the date of Easter for a 500 year period (1600-2099) taken from a public listing of Easter dates published by M. Bednarek.

These frequencies were used to generate the calendar means used by the most recent version of X-13ARIMA-SEATS to deseasonalize the Easter flow regressor generated by the software.

The dates were verified using information provided by M. Montes on various websites, including:

a page of the frequency of the date of Easter for the first 400 years in the Gregorian Calendar (https://www.smart.net/~mmontes/freq3.html)
a page of the frequency of the date of Easter for a 250 year period (https://www.smart.net/~mmontes/freq3.html), and
an application which generates the ecclesiastical calendar for any year after 325 AD (https://www.smart.net/~mmontes/ec-cal.html).

Another page on this website gives a listing of the date of (Western) Easter for this 500 year period.
