To find the Dominical or Sunday Letter for any given Year of our Lord, add to the year its fourth part, omitting fractions, and also the number, which in Table 1. standeth at the top of the column, wherein the number of hundreds contained in that given year is found: Divide the sum by 7, and if there is no remainder, then A is the Sunday Letter; but if any number remaineth, then the Letter, which standeth under that number at the top of the Table, is the Sunday Letter.
