So early Christians decided to celebrate the Christmas of Jesus' birth as1February 25th! Up to now, there have been different celebrations, and there are related activities all over the world, which have long been separated from the small-scale celebrations in which only Christians participate.
Turkey is essential for Christmas, and there are different opinions about why to eat turkey. One thing I know is that a group of English Puritans wanted to move to the American continent for a better life on a Christmas day in AD 1600. As a result, their products were poor and frozen, and many people died of hunger, so they had to catch turkeys that could be found everywhere to cook for the winter.
Eating roast turkey at Christmas has gradually become a habit, and its main meaning is to thank God for giving everyone a well-fed life.
