Yule is a winter festival historically observed by the Germanic peoples that was incorporated into Christmas during the Christianisation of the Germanic peoples. In present times adherents of some new religious movements celebrate Yule independently of the Christian festival. Scholars have connected the original celebrations of Yule to the Wild Hunt, the god Odin, and the heathen Anglo-Saxon Mōdraniht. The term Yule and cognates are still used in English and the Scandinavian languages as well as in Finnish and Estonian to describe Christmas and other festivals occurring during the winter holiday season. Furthermore, some present-day Christmas customs and traditions such as the Yule log, Yule goat, Yule boar, Yule singing, and others may have connections to older pagan Yule traditions.

Christmas is an annual festival commemorating the birth of Jesus Christ, observed primarily on December 25 as a religious and cultural celebration among billions of people around the world. A feast central to the liturgical year in Christianity, it follows the season of Advent or the Nativity Fast, and initiates the season of Christmastide, which historically in the West lasts twelve days and culminates on Twelfth Night. Christmas Day is a public holiday in many countries, is celebrated religiously by a majority of Christians, as well as culturally by many non-Christians, and forms an integral part of the holiday season surrounding it.
