Since the date of Jesus’ birth cannot be determined and there is no relevant record in the Bible, it is academically believed that Christmas is estimated by the date of the Annunciation (March 25), or the ancient Roman farming in the early days of Christianity. Divine Festival (Roman polytheistic belief) was transformed, when society (such as the winter solstice in ancient Rome) used this festival to celebrate the sunshine time from short to long. From the early stage of development to the mid-fourth century, the Western churches began to set Christmas on December 25, the Eastern Orthodox churches set it later on January 7 in the Julian calendar, and the Armenian churches set it on January 6 or January 19 day.
At Christmas, it has the dual functions of religious holidays and cultural festivals. In addition to participating in church ceremonies and activities, related decorations can also be seen on households, line numbers, and streets. It is also an important business season for business activities; and the custom of spending Christmas , And with the influence of modern Western countries, it has expanded to the whole world. However, in areas where Christianity is not mainstream (such as East Asia), in addition to local church groups, Christmas is often linked to consumer activities. Such commercial and folk activities without religious significance can freely participate in those who do not need to accept Western culture. And just like the combination of the "Christmas and New Year season" in Western countries with the Gregorian New Year, the holiday time stretches to several weeks, becoming one of the important shopping and consumption seasons throughout the year. Islamic countries with the same religious lineage are even more special. Although Christmas is also meaningful in Islamic culture and recognizes the status of Jesus, it regards Christmas as a product of distortion and does not allow Christmas-related religious activities. However, in view of the West Most Christmas folk activities have lost their religious color, but Muslims can give each other blessings and participate in reunion activities appropriately.
