VI. Find the remainder of V. divided by 7. (0).
VII. Subtract VI. from 7; this is the number of the dominical letter
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | (7; dominical letter G). |
| A | B | C | D | E | F | G |
VIII. Divide I. by 19, the remainder (or 19, if no remainder) is the golden number. (7).
IX. From the centurial figures of the year subtract 17, divide by 25, and keep the quotient. (0).
X. Subtract IX. and 15 from the centurial figures, divide by 3, and keep the quotient. (1).
XI. To VIII. add ten times the next less number, divide by 30, and keep the remainder. (7).
XII. To XI. add X. and IV., and take away III., throwing out thirties, if any. If this give 24, change it into 25. If 25, change it into 26, whenever the golden number is greater than 11. If 0, change it into 30. Thus we have the epact, or age of the Calendar moon at the beginning of the year. (6).
| When the Epact is 23, or less. XIII. Subtract XII., the epact, from 45. (39). XIV. Subtract the epact from 27, divide by 7, and keep the remainder, or 7, if there be no remainder. (7) | When the Epact is greater than 23. XIII. Subtract XII., the epact, from 75. XIV. Subtract the epact from 57, divide by 7, and keep the remainder, or 7, if there be no remainder. |
XV. To XIII. add VII., the dominical number, (and 7 besides, if XIV. be greater than VII.,) and subtract XIV., the result is the day of March, or if more than 31, subtract 31, and
