Hindu Solar Calendars

Hindu solar calendars are the regional Hindu calendars that give the sun cycle, counted by the sidereal year and by the sun entering each sign at a sankranti, the leading role in reckoning months and festivals. Wikipedia describes the Hindu calendars as sharing a similar underlying concept of timekeeping based on the sidereal year for the solar cycle, while differing in their relative emphasis on the moon cycle or the sun cycle. It is recorded as its own calendar entity so that the holidays and festivals reckoned by it can be grouped and compared in one place, while each holiday entry keeps its own dating facts and sources.
