− | It was observed that the moon came back to the same position in the zodiac once in about 27 days and that each day was marked by the asterism or asterismal group (nakshatra) near which the moon was seen, resulting in calling the asterism ad the day's nakshatra, from which the 27 asterismal segments of the zodiac came into use. The names of these with their presiding deities are enumerated in the Yajurveda, beginning with Krttika, where the spring equinox was situated at that period. The thirteen and a half nakshatras ending with Vishakha, situated in the northern hemisphere, were called devanakshatras, while the thirteen and a half others ending with Bharani were called yamanakshatras as seen in the following passage of the Taittiriya brahmana (1.5.2.7)<ref>K.V.Sarma (1985), [https://archive.org/details/in.ernet.dli.2015.206186/page/n15/mode/2up Vedanga Jyotisa of Lagadha], New Delhi: Indian National Science Academy.</ref> | + | It was observed that the moon came back to the same position in the zodiac once in about 27 days and that each day was marked by the asterism or asterismal group (nakshatra) near which the moon was seen, resulting in calling the asterism ad the day's nakshatra, from which the 27 asterismal segments of the zodiac came into use.
