On January 7 each year, Orthodox Christmas Day presents an exciting chance to revel in another Christmas right as the New Year begins. It's intriguing to note that originally, Christmas was observed 13 days after December 25, the date universally celebrated today. In the Julian calendar, an older system predating the current Gregorian calendar, Christmas was marked on January 7. The Orthodox Church maintains this traditional calendar for celebrating Christmas Day. Orthodox Christians mark the occasion by attending church and partaking in customs such as burning frankincense to honor the Wise Men's gifts to baby Jesus.
