NOTE.—Easter Day (on which all the other movable feasts depend) is always the First Sunday after the Full Moon which happens upon or next after the Twenty-first Day of March; and if the Full Moon happens upon a Sunday, Easter Day is the Sunday after.

Advent Sunday is always the nearest Sunday to the Feast of St. Andrew, whether before or after.

The Calendar as at present used was reformed, in the year of our Lord 1582, by Pope Gregory XIII., who ordered the Historical or Civil year to be thenceforward reckoned from the first day of January. It was not adopted by English-speaking people until January 1, 1753. The Ecclesiastical year still begins on the First Sunday in Advent.

A Rule

FOR FINDING EASTER OF ANY YEAR IN THIS CENTURY OR THE NEXT.

1st. Divide the date of the year by 19, and call the remainder a;

2d. Divide the date of the year by 4, and call the remainder b;

3d. Divide the date of the year by 7, and call the remainder c;

4th. Divide 19a + $\scriptstyle {\left\{{\begin{matrix}\ \\\ \end{matrix}}\right.}$23 [for this Century]
24 [for next Century]$\scriptstyle {\left.{\begin{matrix}\ \\\ \end{matrix}}\right\}\,}$ by 30, and call the remainder d;

5th. Divide 2b + 4c + 6d + $\scriptstyle {\left\{{\begin{matrix}\ \\\ \end{matrix}}\right.}$4 [this Century]
5 [next Century]$\scriptstyle {\left.{\begin{matrix}\ \\\ \end{matrix}}\right\}\,}$ by 7, and call the remainder e;

Then Easter will be the 22d + d + e of March;
⁠or the d + e - 9 of April.

Exceptions.—1st. When Easter would fall on April 26th, put it back to the 19th. 2d. When it would fall on April 25th, put it back to the 18th, unless d = 29, and e = 5.
