usually give the number of the expired year, and not that astronomically current, {e.g., Kaliyuga 4904 means in full phrase "after 4904 years of the Kaliyuga had elapsed") — but when using the name of the cyclic year they give that of the one then current. All the years given in Table I. are current years. The Table to work by is Table XIV.
Rule I. From Table I., cols, i to 7, and Table II., as the case may be, find the year (current) and its initial date, and week-day (cols. 13, 14, Table I.). But if the given Hindu date belongs to any of the months printed in italics at the head of Table XIV., take the next follow- ing initial date and weekday in cols. 13, 14 of Table I. The months printed in the heading in capitals are the initial months of the years according to the different reckonings.
Rule II. For either of the modes of reckoning given at the left of the head-columns of months, find the given month, and under it the given date.
Rule III. From the given date so found, run the eye to the left and find the week-day in the same line under the week-day number found by Rule I. This is the required week-day.
Rule IV. Note number in brackets in the same line on extreme left.
Rule V. In the columns to left of the body of the Table choose that headed by the bracket-number so found, and run the eye down till the initial date found by Rule I. is obtained.
Rule VI. From the month and date in the upper columns (found by Rule II.) run the eye down to the point of junction (vertical and horizontal lines) of this with the initial date found by Rule V. This is the required date A. D.
Rule VII. If the date A. D. falls on or after 1st January in columns to the right, it belongs to the next following year. If such next following year is a leap-year (marked by an asterisk in Table I.) and the date falls after February 28th in the above columns, reduce the date by one day.
N.B. — The dates A.D. obtained from this Table for solar years are Old Style dates up to 8th April, 1753, inclusive.
Example. Find date A.D. corresponding to 20th Paṅguni of the Tamil year Rudhirodgâri, Kali 4904 expired.
| By Rule I. Kali 4905 current, 2 (Monday), 11th April, 1803. |
| By Rule„ II. Tamil Panguni 20. |
| By Rule„ III. (under "2") Friday. |
| By Rule„ IV. Bracket-number (5). |
| By Rule„ V. [Under (5)]. Run down to April 11th. |
| By Rule„ VI. (Point of junctions) March 31st. |
| By Rule„ VII. March 30th. (1804 is a leap year.) |
Answer.—Friday, March 30th, 1804 N.S. (See example 11, p. 74.)
(B.) Conversion of a date A.D. into the corresponding Hindu solar date. (See Rule V.. method B, Art. 137, p. 70.) Use Table XIV.
Rule I. From Tables I., cols, i to 7 and 13, 14, and Table II., as the case may be. find the Hindu year, and its initial date and week-day, opposite the given year A. D. If the given date falls before such initial date, take the next previous Hindu year and its initial date and week-day A.D.
Rule II. From the columns to the left of the body of Table XIV. find that initial date found by Rule I. which is in a line, when carrying the eye horizontally to the right, willi the given A.D. date, and note point of junction.
