Again according to the Arthaśāstra the solar month consists of 30½ days whereas the lunar month consists of 29½ days. Thus the lunar year is said to consist of 354 days and the solar year 366 days. In the five-year cycle the difference between the solar, and the lunar, years is sixty days. These are characterised as adhimāsas.³ Thus "the position of the solstices as well as the occurrence of intercalary months and other items of lunisolar calendar in the Arthaśāstra, are in agreement with the conclusions of the Vedāṅga Jyotiṣa".⁴
