Immaculate Conception of the Blessed Virgin Mary

December 8 (fixed)

Catholic

Catholics celebrate 8 December as the day Mary was conceived without original sin — nine months before her birthday on 8 September. It is a Holy Day of Obligation in many countries and marks the start of serious Christmas preparation.

In the USA it is a public holiday; in the UK it is a normal working day but churches hold special Masses. Pilgrims visit Lourdes, where Mary appeared to St Bernadette.

Eden lists Catholic pilgrimages across Europe.
