COMPUTATION OF DATES.

This may be effected by $$ 20-26. But we may calculate also by means of the column for Julian Calendar' in the tables. Thus in Ex. 1, $ 26, we have Sam. 1233, Bhadrapa'da Sudi 13, Sunday, corresponding to K.Y. 4276, 3rd Aøvina, solar reckoning; and :
Fer. Tithi. ('. An. Jul. Cal. K. Y. 4200 (1) 2.19 6999

Sun (1) eq. O`03 814 31st Aug.
18.32, Bhadrapada sudi. 4276—3101=1175 A.D., 31st August, Sunday.
2. To convert a European date into a Hindu lunar date. Find (a) the corresponding Kaliyuga year by adding 3101 or 3100 as the case requires; (b) by $ 21 find the date corresponding to the Julian day, and by $ 23 compute the corresponding tithi; (c) the lunar month is of the same name as the solar month in which the new moon preceding the date falls, except when the date belongs to the dark fortnight and is to be interpreted according to the Pdrrimanta scheme, when the lunar month takes the name of the following solar month; (d) if the Vikrama era, beginning generally in Karttika, is used, the lunar months Chaitra to Karttika in Table III belong to the preceding year; and (e) if the date is in New Style, it must first be converted into Old Style.
Ex. 1. To find the Hindu date corresponding to 1st June 1891. 1st Jane 1891 corresponds to 20th May (O. S.), K, Y. 4992. By $21, 16+1+14 April=1st May for O Jyaishtha. Hence 20th May 0. S. corresponds to 19th Jyaishtha of the Tables. Now by Tables I-III :

3 = 19 + 14 April. Mon. . (2) eq. 0.42
20th May. . 23-82 or 8-82 badi, i.e., badi 9. The date belonging to the dark fortnight, about the 24th day of the moon's age, new moon must have occurred before 1st Jyaisbtha, or towards the end of Vaisakha; bence in the Amánla scheme the date is Vaisakha badi 9, K. Y. 4992 or Saka 1818; but being before Kårttika, it is in Sarvat 1947. In the Parrimanta scheme it is Jyaishtba badi 9.
Es. 2. For 11th February 1878.
11th February is 30th January 0. S. and this falling before Chaitra, the year K. Y. is 1978. 0 Phâlguna=16+ 18 January=29th January. Hence 30th January=1st Phâlguna. Then

30th Jan.
8:16 Mágba sudi. Hence the 9th tithi sudi ended on Monday, 30th January 0. S., or 11th February N. S., and new moon occurred about 23rd Magha; bence the date in both schemes is Magha sudi 9, Saka 1799 or Survat 193+.
