The Epiphanytide tradition of chalking the door involves writing C✝M✝B (representing the names of the Three Wise Men as well as the Christian prayer Christus mansionem benedicat) with the year flanking both sides on one's door, as seen here on an apartment door in the Midwestern US.

The Epiphany season, also known as Epiphanytide or the time of Sundays after Epiphany, is a liturgical period, celebrated by many Christian Churches, which immediately follows the Christmas season. It begins on Epiphany Day, and ends at various points (such as Candlemas) as defined by those denominations. The typical liturgical color for the day of Epiphany is white, and the typical color for Epiphany season is green.

Popular Epiphanytide customs include Epiphany singing, chalking the door and families inviting their pastor to bless their home.
