Christmas Day (December 25) and the Immaculate Conception (December 8) are always days of obligation. Christmas and Easter (which always falls on Sunday) are  Holy Days.  However, if any of the other holy days falls on a Saturday or Monday, Catholics are not obligated to attend Mass .  Some dioceses,including The Diocese of Wilmington, moved the Ascension from Thursday to the closest Sunday.   Please check the latest bulletin for updated information and the Mass schedule.
