Feast of the Immaculate Conception (December 8): Meaning & Traditions

The Feast of the Immaculate Conception is celebrated on December 8 by the Catholic Church. It honours the belief that the Virgin Mary was conceived in her mother’s womb without original sin. In many countries — including Italy, Spain, Portugal, Austria, Argentina, Chile, Colombia, Nicaragua, Paraguay, Peru, Panama and the Philippines — it is also a public holiday that opens the Christmas season.

A Common Mix-Up: It Is Not About Jesus’ Birth

Many people think the Immaculate Conception refers to Jesus being conceived by the Virgin Mary. That event is the Annunciation (March 25) and the doctrine of the Virgin Birth. The Immaculate Conception is about Mary’s own conception by her parents, traditionally named Joachim and Anne. That is also why the feast falls exactly nine months before the Nativity of Mary on September 8.

Immaculate Conception	December 8	Mary conceived free from original sin

December 8 is a Holy Day of Obligation for American Catholics, though it is not a federal holiday.
