The Ember days are four seasonal times of prayer and fasting, and an ancient part of the Ordinariate's English Christian patrimony. The word comes from “Quattember” or “the four times of the year” as the Ember days take place in Advent, Lent, Whitsuntide (the octave of Pentecost), and September following Holy Cross Day. Here are details from St. Alban's Catholic Church in Rochester, NY.
