How to Determine What Offices to Read on Any Day
The Christian Year, as organized in The Book of Divine Worship, consists of six seasons:
- four weeks in Advent (of which the fourth week may be partial)
beginning no earlier than November 27th and no later than December 3rd,
- twelve days in Christmas, from December 25th through January 5th,
- five to ten weeks in Epiphany
(of which the first week may and the last week must be partial),
beginning on January 6th (or, in the U.S.A., on the Sunday from January 2nd to January 8th),
- seven weeks in Lent (of which the first week is partial),
beginning no earlier than February 4th and no later than March 10th,
- seven weeks in Easter, beginning no earlier than March 22nd and no later than April 25th, and
- 24 to 29 weeks in Pentecost, beginning no earlier than May 10th and no later than June 13th.
Additionally, the Church's calendar contains days of commemoration and instruction classified according
to their importance. They are called, in order of precedence:
- Solemnities (so marked and printed in boldface in the BDW)
- Feasts (so marked and printed in boldface in the BDW)
- Memorials (so marked in the BDW)
- Optional Memorials (printed in italic in the BDW)
On this website, to find today's readings go the season calendar on the Home Page, click on the current season, then
click on the link to the week in the Church Year closest to, but not later than,
today's date. A new window will open with links to the offices corresponding to today's position in the Christian
Year. The window also displays a listing of days from the Church's calendar falling on or near today. The rules for
determining which day has precedence when two or more observances fall on the same day are set forth in the table below.
In general, Sundays have precedence over most feasts and memorials, but not over solemnities.
