This is hard to believe. I asked ChatGPT "What is the Gregorian
date of Orthodox Easter in 2025?" and it replied "...April
27, 2025. Even though the Orthodox Church calculates Easter 
based on the Julian calendar, the corresponding date in the 
Gregorian calendar (used in most of the world today) is April 27."
But I asked Google Search the same question and it replied
"In 2025, Orthodox Easter, also known as Pascha, will be 
celebrated on Sunday, April 20th, according to the Gregorian 
calendar." Everything else returned in the Google search
confirms that latter answer. It looks like ChatGPT really
blew this one.
