Why Do 250 Million Christians Celebrate Christmas on January 7?

Millions of Christians, including those in Eastern Europe and across the Arab world, such as Palestine and Egypt, are celebrating Christmas today.

Christmas Day commemorates the birth of Jesus Christ, who was born in Bethlehem.

However, for these communities, which number about 250 million people, the most important day of the season is not December 25, but January 7. In this visual explainer, Al Jazeera illustrates what cultural and historical reasons led to this difference in Christmas celebrations.
