Dominical letters are letters A, B, C, D, E, F and G assigned to days in a cycle of 7 with the letter A always set against 1 January as an aid for finding the day of
week of a given calendar date and in
calculating Easter. A common year is assigned the dominical letter of its first Sunday. For example 2003 has
5 January as its first Sunday, so it has dominical letter E.In
leap years, the leap day may or may not have a dominical letter. In the original 1582 Catholic version, it did, but in the 1752 Anglican version it did not. The Catholic version caused February to have 29 days by doubling the sixth day before
1 March, inclusive, because
24 February in a common year is marked "duplex", thus both halves of the doubled day had a dominical letter of F. The Anglican version added a day to February that did not exist in common years,
29 February, thus it did not have a dominical letter of its own.
