History of Dharmashastra (Ancient and Mediaeval Religious and Civil Law in India) v6.c82.94.2

v6.c82.94.2

Here there is a reference to seasons, six of which have two months each, the 7th has only one (viz. 13th or intercalary month) and that the 13th month is not fit for religious rites. The Atharvaveda V. 35. 4⁷⁰⁸ also states that saṃvatsara has twelve spokes and the months have 30 spokes This explains Ṛg. I. 164. 11-13 and 48. In the Brāhmaṇas also the year is said to have 360 days and 720 days and nights together; Śatapatha IX. I. 1. 43, Ait. Br. VII, 7 also say the⁷⁰⁹ same. We have also to recognize that the Vedic saṃhitās and Brāhmaṇas speak of a 13th month that was intercalated. About Varuṇa the Ṛgveda says⁷¹⁰ 'He knows the twelve months with their progeny (the days) and also the month that is added.' The Tai. S. (IV. 6. 7. 1-2) refers to a year of twelve months and also of 13 months. The Kauṣītaki Br 19. 2 speaks of the 13th month. The Tai. S. (I. 14. 4, VI. 5. 3 4) expressly mentions the 13th month called 'Saṃsarpa or Amhaspatya'. It is called Amhasaspati in Vāj. S. (VII. 30 and XXII. 31) and Saṃsarpa in Maitrāyaṇī S. III. 12. 13. The Kauṣītaki Brāhmaṇa connects the 13th month with the Śunāsīrīya sacrifice.⁷¹¹ The Maitrāyaṇī Saṃhitā (I. 10.
