What is Christmas?
Christmas (often written as Xmas) is a major holiday celebrated by Christians worldwide to commemorate the birth of Jesus Christ. In many places it’s also a cultural holiday—meaning you may see decorations, gift-giving, music, and seasonal events even where Christmas is not an official public holiday.

While “Christmas Day” usually means December 25, the date can differ by tradition and calendar.

| Regional / optional holiday | Some regions observe Christmas; others operate normally. | Check state/province/city calendars when traveling or doing business. |
| Cultural observance | Decorations and events exist, but offices may remain open. | Less impact on working hours; more seasonal shopping and events. |
