who celebrates christmas on january 6th

There are many countries and cultures that celebrate Christmas on different days. The date of December 25th is not universally observed as Christmas Day. In some parts of the world, such as Russia, Christmas is celebrated on January 7th, which is 13 days after the date of December 25th. The reason for this discrepancy is due to the difference in calendars used in different regions. Many Orthodox Christians in Russia follow the Julian calendar, which is a 13-day difference from the Gregorian calendar used in most Western countries.
