The Table of Moveable Feasts lists a Golden Number, a Sunday Letter, and an Epact for each year. What are these and how are they used?
The Golden Number, Epact, and Sunday Letter are useful in calculating the date of Easter. If you’re looking for a detailed description of where each of these figures comes from, I recommend the Calendar FAQ, but I can give you a brief introduction to each. For more information about using the Golden Number and Sunday Letters, see a Table to Find Easter and the General Tables for Finding Easter Day.
