The First Sunday of Advent, which we celebrated yesterday, marks the beginning of the church's liturgical year, which, of course, makes no sense to most people who are satisfied that the new year begins Jan. 1.
But that is only the case where the Gregorian calendar, traditionally attributed to Gregory XIII (pope from 1572-85), is normative. In fact, Christians, who had followed the Julian calendar until 1582, used to celebrate New Year's Day on March 25, the feast of the Annunciation.
For the Chinese and other Asian communities, New Year's Day has a changeable date, falling somewhere between January 10 and February 19. This year the Lunar New Year begins on Sunday, February 14.
The Jewish New Year (Rosh Hashanah) is also a moveable holiday, observed sometime in September or early October. This past fall it was celebrated beginning at sundown on Friday, September 18, and continuing on Saturday, the 19th.
The church's First Sunday of Advent usually occurs in late November, as it did this year, but it can fall as late as Dec. 2. When that happens, as it last did in 2006, the Fourth Sunday of Advent is also Christmas Eve.
