Chalking the door

Common card · No. 287804

Chalking the door is a Christian Epiphanytide tradition used to bless one's home. It is normatively in the pattern of four crosses positioned in between the letters C, M and B, often linked to the traditional initials of the three wise men, as well as the Christian prayer "Christus mansionem benedicat" (Latin for "May Christ bless this house") which are surrounded by the first two and last two digits of the current year (e.g. 20 ✝ C ✝ M ✝ B ✝ 26). The practice of chalking the door originated in medieval Europe, though it has spread throughout worldwide Christendom.
