Advent Sunday, also called the First Sunday of Advent or First Advent Sunday, among the Western Christian Churches, is the first day of the liturgical year and the start of the season of Advent.
On the First Sunday of Advent, Christians start lighting their Advent wreaths, and praying their Advent daily devotional; believers may also erect their Christmas tree or Chrismon tree, light a Christingle, as well as engage in other ways of preparing for Christmas, such as setting up Christmas decorations, a custom that is sometimes done liturgically through a hanging of the greens ceremony.
