Easter and Pentecost Dates

By Sir Knightly

Introduction

by Greg Stafford

Pendragon mentions the schism between the Roman and the British churches during the reign of King Arthur, with calculating the date for Easter being one of the main points of contention. It has little actual impact on the game, unless the players and gamemaster wish the religious conflict to be more than a lighthearted rivalry. Nonetheless, sometimes it is just cool to have some information about it, whether we use it or not.

Sir Knightly has provided us with that coolness.

Here is a chart that shows the Easter and Pentecost dates for each year of the Pendragon campaign, for both the Roman and the British Churches.

The Roman dates are those used by the Roman church as laid down by the Council of Nicaea in AD 325.

The British dates are calculated from the reconstructed 84 year cycle used by the British Church.

Notes

I found 2 small errors in the thesis chart.The charts in the thesis list April 19 as the date of Easter for 504, but April 19 would be a Monday. (which is not possible)

In the McCarthy/Ó Cróinín this date is correctly listed as April 18.

In the McCarthy/Ó Cróinín (and replicated in the Cullen's thesis) Easter 496 is listed as April 4. I believe the correct date is April 14.
