The Feast of the Immaculate Conception is Sunday, December 8th, but is transferred to Monday, Dec. 9th.
There will be masses on Monday the 9th at 6:45 am, 9 am, and 10 am at Annunciation and at 9 am and 7:30 pm at Our Lady of Fatima.
(However, the obligation to attend Mass is dispensed because December 8 falls on Sunday.)
