The holiday is celebrated on December 25th and has become a global celebration that is observed by people of various faiths and backgrounds. Some people may celebrate the holiday in a secular way, focusing more on the traditions and customs associated with the holiday rather than its religious significance. However, the holiday is still primarily associated with Christianity and the birth of Jesus.
