COMPUTATION OF DATES.

The Tables : the Julian Calendar. 19. The tables are based, as far as possible, on the Hindu solar calendar; but for simplicity a solar calendar is employed in them in which the dates may differ by one day from the Hindu solar dates. As the Hindus scarcely ever used the solar calendar by itself, this difference is of no practical moment; in the sequel, however, will be shown how the true solar date may be elicited from the tables. It is only necessary here to show how a date in the tables may be converted into the corresponding Christian date, old style. For this purpose the subjoined tables may be used.

PART II.-ODD YEARS OF THE CENTURY K.Y. For the years 1, 2, 5, 6, 9, 10, 13, 17, 21, 25, 29, 33, 37, 41, subtract 1.

ing year K,Y. 12th February C.Y. 14th March C.Y. 18th February L.Y. 13th March L.Y.
Note.--If the date falls in a common Julian year, the
first date should be taken; if in a leap year, the second. The italicised months contain 31 days.
20. Rule for finding the Julian date corresponding to a date in the Tables : Ex, 1. for 8940 K.Y. 26th Bhadrapada. Take the equation of the century K.Y. from Part I, in this case 7; make the alteration prescribed by Part II, here none; add the result to the Julian date placed below the given Hindu month, here 7 + 17 - 24th July. This is the Julian date corresponding to the first day of the solar month, which in the table is numbered O. Add to the above result the number of the given day, here 26; the sum is the corresponding date of the given day, diz. 24 + 25 = 49th July, i.e. 18th August. Accordingly 3940 K.Y., 25th Bhadrapada is A.D. 839, 18th August, 0.8. Example 8: 4237 K.Y., 28th Mágba.
10-1= 9.9 + 14th December + 28 = 51st December 1186, i.e. 20th January, 1187, 0.8. Example 3 : 4584 K.Y., 13th Karttika.
12 + 1 + 17th September + 13 = 43rd September, i.e. 18th October A.D. 1483, 0.8.
