In vedic astronomy, months were lunar and measured from full moon to full moon and also from new moon to new moon.<ref name=":2" /> While the year, generally called by the terms sama, vatsara, and hayana in the vedic literature, was measured from one winter solstice to the next.<ref name=":1" /><ref name=":2" /> In fact, Kaushitaki brahmana (19.3) gives an interesting account of how the year-long yajna commenced at one winter solstice and continued until the next. It says, “On the new moon of Magha, the Sun rests, about to turn northwards. The hotas also rest, about to begin with the introductory Atiratra. Thus, for the first time, the hotas obtain the Sun. On him, they lay hold with the Chaturvimsha rite; that is why the laying hold rite has that name. The Sun then goes north for six months, while the hotas follow him with six day rites in continuation. Having gone north for six months, the Sun stands still, about to turn southwards. The hotas also rest, about to begin with the Vishnuvanta (summer solstice) day. Thus, for the second time, they obtain the Sun. The Sun then goes south for six months and the hotas follow him with six day rites in reverse order. Having gone south for six months, the Sun stands still, being about to turn north and the hotas also rest, about to begin with the Mahavrata day.

In vedic astronomy, months were lunar and measured from full moon to full moon and also from new moon to new moon.<ref name=":2" />  

This year of vedic astronomy seems to have been a seasonal or tropical one. Therefore, in the early stages, the names of the seasons were used as synonyms of a year.

The lunar or synodic month was measured from full moon to full moon or from new moon to new moon (Taittirīya-saṃhitā, 7. 5. 6. 1<ref>Taittiriya Samhita, Kanda 7, [https://sa.wikisource.org/wiki/%E0%A4%A4%E0%A5%88%E0%A4%A4%E0%A5%8D%E0%A4%A4%E0%A4%BF%E0%A4%B0%E0%A5%80%E0%A4%AF%E0%A4%B8%E0%A4%82%E0%A4%B9%E0%A4%BF%E0%A4%A4%E0%A4%BE(%E0%A4%B5%E0%A4%BF%E0%A4%B8%E0%A5%8D%E0%A4%B5%E0%A4%B0%E0%A4%83)/%E0%A4%95%E0%A4%BE%E0%A4%A3%E0%A5%8D%E0%A4%A1%E0%A4%AE%E0%A5%8D_%E0%A5%AD/%E0%A4%AA%E0%A5%8D%E0%A4%B0%E0%A4%AA%E0%A4%BE%E0%A4%A0%E0%A4%95%E0%A4%83_%E0%A5%AB Prapathaka 5].</ref>) as is the case even now.

There is evidence to show that to make the lunar year correspond to the solar year 12 days were intercalated after every lunar year and one month was dropped after every 40 years.5 (5Law, N. N., Age of the Ṛgveda, pp. 20, 28–29.) At a later stage this correspondence was established by evolving a cycle of five solar years with 62 lunar months. This cycle was called a yuga.<ref name=":2" />

The names Caitra etc. based on the nakshatras in which the Moon becomes full do not occur in the early saṃhitās and brāhmaṇas but such terms as phalgunī-pūrnamāsī, citrā-pūrnamāsī, etc. are found to occur in the Taittirīyasaṃhitā (7. 4. 8).<ref>Taittiriya Samhita, Kanda 7, [https://sa.wikisource.org/wiki/%E0%A4%A4%E0%A5%88%E0%A4%A4%E0%A5%8D%E0%A4%A4%E0%A4%BF%E0%A4%B0%E0%A5%80%E0%A4%AF%E0%A4%B8%E0%A4%82%E0%A4%B9%E0%A4%BF%E0%A4%A4%E0%A4%BE(%E0%A4%B5%E0%A4%BF%E0%A4%B8%E0%A5%8D%E0%A4%B5%E0%A4%B0%E0%A4%83)/%E0%A4%95%E0%A4%BE%E0%A4%A3%E0%A5%8D%E0%A4%A1%E0%A4%AE%E0%A5%8D_%E0%A5%AD/%E0%A4%AA%E0%A5%8D%E0%A4%B0%E0%A4%AA%E0%A4%BE%E0%A4%A0%E0%A4%95%E0%A4%83_%E0%A5%AA Prapathaka 4].</ref>
