Greek Friend of mine said that Greek Orthodox and Roman Catholic Easter is on the same day from now on. wife said only once every few years, and this is how i understood it. has something changed in the Greek Orthodox Easter date?
No, I don't think we will change.
The Orthodox still use the date for Pascha the way the Christian church did before the schism:
The first Sunday, after the full moon, after the equinox, "but after the Passover [the Last Supper was the Passover, Pascha]."
After the western countries changed to the new calendar, they omitted the last part. However, the Jews still determine Passover based on the old calendar. The Orthodox Christians believe you cannot have the Easter services before the Passover (Last Supper) has occurred. This is why the dates are often weeks apart. But every few years the criteria work so the western Easter falls on the same day.
I don't think the Orthodox Christians would change this.
