Interesting point. Since the 325AD and First Council of Nicaea (i.e. Iznik, Turkey) the Church had made March 21st the spring Equinox (reflecting to the reality of equinox then the council was held). Yet within Celtic Easter controversy it is cited that the Irish held a belief that the spring Equinox was on March 25th. So the Rome calculation could to their mind wrongly place Easter before the time that the Irish considered to be the Spring Equinox.
Yet why would Christian Irish consider spring Equinox as being March 25th in their calculation of Easter? For they had become Christians after the First Council of Nicaea define March 21st as the Spring Equinox?
Pope Benedict XVI’s work tells us that: “… March 25. In Gaul, right up to the sixth century, this was kept as the immovable date of Easter”.
So did the Irish Christian tradition most likely come not directly from Nicaea, but from an alternative tradition - possible Gaul?
However we haven’t shown that the pre-Christian Irish were following Julian date for the Spring Equinox. Irish pre-Christians could well have been celebrating the time (plus or minus) of the actual physical equinox and the local Christian where in need of tradition to offset this pre-Christian celebration?
(Within the same century that St Patrick’s day most likely came into existence, there was a story of St Patrick’s disruption of a major pre-Christian festival (a ‘heathen Easter’ to say) at Tara.)
