In many Western Christmas traditions, Santa Claus is said to deliver presents on Christmas Eve.
Christmas Eve is the evening and night before Christmas Day, observed on December 24 in most Western Christian calendars. The tradition places Santa’s visit overnight so children discover gifts when they wake on Christmas morning.
This timing is closely connected with stories of Santa traveling by sleigh, entering homes through the chimney, and leaving presents near a Christmas tree or fireplace. Customs vary worldwide: some gift-bringers arrive on Saint Nicholas Day, Epiphany, or New Year’s Eve instead.
Christmas Eve should not be confused with Christmas Day. Santa’s fictional overnight journey happens before December 25, while Christmas Day is traditionally when families open presents and celebrate the holiday.
