Upcoming Ember Days are September 17, 19, and 20. The Almanac traditionally marks the four periods formerly observed by the Roman Catholic and Anglican churches for prayer, fasting, and the ordination of clergy. These Ember Days are the Wednesdays, Fridays, and Saturdays that follow in succession after (1) the First Sunday in Lent; (2) Whitsunday/Pentecost; (3) the Feast of the Holy Cross, September 14; and (4) the Feast of St. Lucia, December 13. The word ember is perhaps a corruption of the Latin quatuor tempora, "four times." Folklore has it that the weather on each of the three days foretells the weather for three successive months; for example, in the case of September's Ember Days: Wednesday, September 17, forecasts the weather for October; Friday, September 19, for November; and Saturday, September 20, for December.
