In Russia, Christmas is celebrated on January 7th. This is due to the difference in the Julian and Gregorian calendars, which Russia has used for centuries. The Russian Orthodox Church follows the Julian calendar, which has 13 days behind the Gregorian calendar. Therefore, Christmas in Russia falls on January 7th according to the Gregorian calendar. This can cause some confusion for Russians living abroad who follow the Gregorian calendar and celebrate Christmas on December 25th. However, many Russians still celebrate both Christmas and New Year's Eve, which is also a major holiday in Russia.
