the required English date, remembering that when this is over 365 in a common year or 366 in a leap-year the date A.D. falls in the ensuing A.D. year.
Rule III. From the sum of the second addition cut out sevens. The remainder shews the required day of the week.
Rule IV. If the Hindu date is in a luni-solar year where, according to cols. 8 to 12, there was an added (adhika) or suppressed (kshaya) month, and falls after such month, the addition or suppression or both must be allowed for in calculating the collective duration of days; i.e., add 30 days for an added month, and deduct 30 for a suppressed month.
Rule V. The results are Old Style dates up to, and New Style dates from, 1752 A.D. The New style in England was introduced with effect from after 2nd September, 1752. Since the initial dates of 1752, 1753 only are given, remember to apply the correction (+ 11 days) to any date between 2nd September, 1752, and 9th April, 1753, in calculating by the Hindu solar year, or between 2nd September, 1752, and 4th April, 1753, in calculating by the Hindu lunisolar year, so as to bring out the result in New Style dates A.D. The day of the week requires no alteration.
Rule VI. If the date A.D. found as above falls after February 29th in a leap-year, it must be reduced by one day.
Example 1. Required the A.D. equivalent of (luni-solar) Vaiśâkha śukla shashṭhî (6th), year Śârvari, Śaka 1702 expired, (1703 current).
The A.D. year is 1780 (a leap-year). The initial date 5th April (96), and Wednesday, (Table I., cols. 5, 19, 20).
| d. | w. | |||
| State this accordingly | 96 | 4 | ||
| Collective duration (Table III., col. 3a) | 30 | 30 | ||
| Given date (6) − 1 | 5 | 5 | ||
| 131 | ||||
| 1 | (Rule VI.) | |||
| 130 | 39 | ÷ 7 = Rem. 4 | ||
The result gives 130 (Table IX.) = May 10th, and 4 = Wednesday. The required date is therefore Wednesday, May 10th, A.D. 1780.
Example 2. Required the A.D. equivalent of (luni-solar) Kârttika śukla paṅchamî (5th) Śaka 1698 expired (1699 current).
The A.D. year is 1776, and the initial date is 20th March (80), Wednesday (4). This is a leap-year, and the Table shews us that the month (6) Bhâdrapada was intercalated. So there is both an adhika Bhâdrapada and a nija Bhâdrapada in this year, which compels us to treat the given month Kârttika as if it were the succeeding month Mârgaśîrsha in order to get at the proper figure for the collective duration.
