| | CATHOLIC ENCYCLOPEDIA: Epact |
 | | This addition of one to the Epacts is known as the Lunar Equation, and occurs at the beginning of the years 1800, 2100, 2400, 2700, 3000, 3300, 3600, 3900, 4300, 4600, etc. A second disturbance of the Epacts is caused by the occurrence of the non-bissextile centurial years. |
 | | From this arrangement it is evident that if, for example, the Epact of a year is X, the new moons will occur in that year on the days before which the Epact X is placed in the calendar. |
 | | To take an example: the Epact of 1696 (its Golden Number being 6) is XXVI, and since this Epact is found opposite 4 February in the Church calendar we know that in 1696 the new moon happened on that date and that consequently 23 February was the twentieth day of the calendar moon. |
