TERMINUS PASCHALIS. - It is the date of the day coinciding with the XIV moon of the “first month” (nīzān, according to the Jewish liturgical calendar), which fell on the spring equinox or immediately followed II. The Council of Nicaea (325) established the celebration of Christian Easter on this basis, fixing it on the Sunday following the t. p.
In order to determine the date, certain tables were compiled correlating the t. p. with the golden numbers, modified after the Gregorian reform. For the period between 1900 and 2199 the correspondence is as follows:
| Golden no. T. p. | 1 14 Apr. | 2 3 Apr. | 3 23 March | 4 11 Apr. |
|---|---|---|---|---|
| Golden no. T. p. | 5 31 March | 6 18 Apr. | 7 8 Apr. | 8 28 March |
| Golden no. T. p. | 9 16 Apr. | 10 5 Apr. | 11 25 March | 12 13 Apr. |
| Golden no. T. p. | 13 2 Apr. | 14 22 March | 15 10 Apr. | 16 30 March |
| Golden no. T. p. | 17 17 Apr. | 18 7 Apr. | 19 27 March |
Thus, for 1953, whose golden number is 16, the t. p. falls on 30 March, which is a Monday, and Easter therefore falls on the following Sunday, 5 Apr.
