Christmas Eve (December 24 or January 5)
- In the Byzantine Rite, Christmas Eve is referred to as Paramony ("preparation"). It is the concluding day of the Nativity Fast and is observed as a day of strict fasting by those devout Byzantine Christians who are physically capable of doing so. In some traditions, nothing is eaten until the first star appears in the evening sky, in commemoration of the Star of Bethlehem.
- During the Reformation in 16th- and 17th-century Europe, many Protestants changed the gift bringer to the Christ Child or Christkindl, and the date of giving gifts changed from December 6 to Christmas Eve. It is the night when Santa Claus makes his rounds delivering gifts to good children. Many trace the custom of giving gifts to the Magi who brought gifts for the Christ child in the manger.
