In Ancient Indian astronomy, there are 27 nakshatras , or sectors along the ecliptic. A list of them is first found in the Vedanga Jyotisha, a text dated to the final centuries BCE[citation needed]. The Nakṣatra system predates the influence of Hellenistic astronomy on Vedic tradition, which became prevalent from about the 2nd century CE. There are various systems of enumerating the Nakṣatra-s;[clarification needed] although there are 27-28 days to a sidereal month, by custom only 27 days are used. The following list gives the corresponding regions of sky.[1] Months in the modern Indian national calendar -- despite still carrying names that derive from the nakshatras -- do not signify any material correlation. It stands to reason that during the original naming of these months -- whenever that happened -- they were indeed based on the nakshatras that coincided with them in some manner. The modern Indian national calendar is a solar calendar, much like the Gregorian calendar wherein solstices and equinoxes fall on the same date(s) every year.
