Frequency of the Date of Easter 1600 to 2099

 

Introduction

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

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:

Another page on this website gives a listing of the date of (Western) Easter for this 500 year period (easter500.html). The dates of Easter are also available in the following formats:

  • an Excel file with the date of Easter for this 500 year period and the frequencies of the occurance of the date of Easter (easter500.xls).
  • an ASCII text file with the dates of Easter for this 500 year period (easter500.txt). This file can be used with the GenHol utility available on this website.

Note that a viewer for Excel filesLink to a non-federal Web site is available from the Microsoft Office website.
