The Ember Weeks—the weeks in which the Ember Days occur—are the week between the third and fourth Sundays of Advent, between the first and second Sundays of Lent, the week between Pentecost and Trinity Sunday, and the week beginning on the Sunday after Holy Cross Day (September 14), the liturgical Third Week of September.
A thorough explanation of the Ember Days can be found at Fisheaters.
