Indian Calendar System in Islamic Astronomy Perspective

Abstract

The Indian calendar, or the Indian calendar system, is a unique calendar. This is because many regions have their own version of the calendar. The Indian calendar uses two calendar systems in general, namely, according to solar calculations and according to solar lunar calculations. This paper discusses the Indian calendar system from the perspective of Islamic astronomy. The method used in this research is library research(library research). From the perspective of Islamic astronomy, the Indian calendar is not very suitable because it does not use calculations according to the movement of the moon. The Saka Bali calendar is one of the calendars whose calculations are close to the Hijri calendar or Islamic astronomy because it uses calculations for the movement of the moon and the sun.
