The Ember Days, although the occasion of their institution is uncertain, are a reminder of these ancient days of devotion. Wednesday, Friday, and Saturday were days of particularly devotion in the early church: Wednesday, as recalling the betrayal of our Lord, and Friday in memory of His Passion, Saturday was later added to these days of prayer and penance as a continuation of Friday, and as far back as the second century they were set apart as Stational days, that is as days of special religious service and fasting.

They fall after Ash Wednesday, after Whitsunday, after September 14, and after December 13. The Ember Days are kept on Wednesday, Friday and Saturday in a week of each of the four seasons of the year.
