“Ukraine’s Orthodox worshippers have always celebrated Christmas on January 7 — but that will change for many this year, with the Orthodox Church of Ukraine (OCU) for the first time allowing its congregations to celebrate on December 25.
This move creates a dividing line with Russia, which celebrates on January 7, and is likely to widen a rift between Ukraine’s two feuding churches.
In 2018, the OCU split from the similarly named Ukrainian Orthodox Church (UOC), which is seen as politically linked to Moscow and is facing public demands for its closure amid accusations that it is a hotbed of fifth columnists — that is, people who support and secretly help the enemies of the country they live in.”

“According to Yevstratiy, already before the invasion, more than a third of Ukrainians wanted to change to the Gregorian calendar. “The numbers are probably higher now, and we are having an experiment to try to understand what worshippers really want,” he said.
“We are not moving the day of Christmas,” he added. “This will be an additional day of worship,” with celebrations held in accordance with the official Julian church calendar.
In the meantime, the church will “consider what to do in the future, and we will observe closely how many congregations take up the opportunity to celebrate on December 25,” Yevstratiy continued.”

“Political differences underpin the the split between the churches of the predominantly Orthodox nation: Western-oriented OCU churches offered support to the Maidan protesters of 2014, which toppled Viktor Yanukovych, Moscow’s viceroy in Ukraine. Over recent years, the church been a strong advocate of Ukrainian statehood and sovereignty.
The Russian-tied UOC claimed in May to have ended its subordination to Moscow’s Metropolitan Kirill, a vociferous supporter of Russian President Vladimir Putin — although few believe the split is sincere. The church’s spokesperson, Metropolitan Klyment, dismissed as a political stunt the OCU’s decision to allow its congregants to celebrate on December 25, claiming it as evidence of how the rival church is not a religious institution but a political organization eager to do the government’s bidding.”
…
“The Kyiv-headquartered UOC dismisses the charge that its decision to allow congregations to celebrate Christmas on December 25 has anything to do with politics. Instead, it is merely responding to “numerous requests and taking into account the discussion that has been going on for many years in the church and in society.””

“The Gregorian calendar was introduced by Pope Gregory in 1582; the Julian calendar, established by Julius Caesar, harks back to 46 B.C.”
