Holy Days of Obligation for the year 2021 including Mass times
(assuming we get back to normal, those days, in addition to Sundays, we are obliged to worship God at Mass)
“The proclamation of the date of Easter and the other moveable feasts on Epiphany dates from a time when calendars were not readily available. It was necessary to make known the date of Easter in advance, since many celebrations of the liturgical year depend on its date. The number of Sundays that follow Epiphany, the date of Ash Wednesday, and the number of Sundays that follow Pentecost are all computed in relation to Easter.
“Although calendars now give the date of Easter and the other feasts in the liturgical year for many years in advance, the Epiphany proclamation still has value. It is a reminder of the centrality of the resurrection of the Lord in the liturgical year and the importance of the great mysteries of faith which are celebrated each year” (from the USCCB website).
