The Solemnity of the Immaculate Conception celebrates the conception of the Blessed Virgin Mary in the womb of her mother, Saint Anne. This conception is called "immaculate" because Mary was conceived without Original Sin. When is the Feast of the Immaculate Conception?

How Is the Date of the Feast of the Immaculate Conception Determined?

The Feast of the Immaculate Conception is normally celebrated on December 8, exactly nine months before the Nativity of the Blessed Virgin Mary (September 8).

However, because the celebration of the Immaculate Conception falls during Advent every year, the feast is transferred to December 9 when December 8 falls on a Sunday (as it does in 2019). While the Solemnity of the Immaculate Conception is a Holy Day of Obligation (even when December 8 falls on a Saturday or Monday), the obligation is abrogated when the celebration of the feast is transferred to December 9.
