" Introduction

Hindu Calendars are by far the nearest approaches to the actual machinery of astronomical phenomena governing life on our planet. (Hashim Amir Ali)

The are more than 30 variations of the calendars used in India, the best known of which is the classical Hindu Calendar Surya Siddhanta which is said to have been revealed to Asura Maya the Assyrian at the end of the last Golden Age (2,163,154 BCE). The Hindu lunisolar calendar is similar to the Chinese calendar, but varies in terms of application of fixed ancient methods to approximate true sun and true moon, based on sidereal year. Hindu longitudes are sidereal, having their origin near Piscium, the 6th brightest star in Pisces. However, having sidereal longitudes doesn’t really affect the calculations. The calendar is lunisolar in the sense that it uses lunar months to approximate the sidereal year. The epoch used for Hindu calendars dates to January 23, -3101 in the Gregorian Calendar. The era in the Indian calendar is called the Vikram Era, or the Vikram Samvat, which began in 57 BCE.

There are two types of Hindu Lunisolar Calendars:

Amanta – one which is based on new moon ending of the lunar month
Parimanta – the other is based on full moon ending of the lunar month

We would be designing the Amanta Lunisolar Calendar for KCalendarSystem"
