(dominical letter). That letter, of the first 7 of the alphabet, which falls on Sunday when the letters are assigned in order to the days of the yr., beginning January 1 (leap yr. requiring adjustments). Used with the Golden Number, or Prime, for the yr., and in connection with a calendar table found, e.g., in a prefix to the Book of Common Prayer, to determine the date of Easter in any given yr. The Golden Number is determined by mathematical calculation (e.g., for 1973: take 73, add 1, making 74: divide by 19; the remainder  is the Golden Number for 1973; if, for another yr., there is no remainder, the Golden Number is 19). For dates of Easter see also Easter Dates.
