Christmas in Eastern Christianity is observed on January 7 and is celebrated by various Eastern Orthodox, Oriental Orthodox, and Eastern Catholic Churches, which still adhere to the Julian calendar. The holiday is preceded by a 40-day Nativity Fast, during which many abstain from certain foods, culminating in Christmas Eve services that include the Royal Hours and Vespers, followed by a traditional supper featuring twelve Lenten dishes. On Christmas Day, families often share a festive meal that breaks the fast, enjoying foods that were previously prohibited. In some countries, such as Russia, Ukraine, and Serbia, Christmas is a public holiday, while in Ukraine, both January 7 and December 25 are recognized as public holidays. Carol singing remains a tradition, particularly in rural areas, where children dress in costumes and sing carols in exchange for treats. Despite its religious significance, many post-Soviet states have seen Christmas become less about religious observance and more about leisure time, with secular aspects now largely associated with New Year's celebrations.
