Indian Calendrical Calculations

  • Nachum Dershowitz
  • Edward M. Reingold


We analyse various Indian calendars. We discuss the Indian day count, a generic solar calendar that generalizes various calendars including the mean Indian solar calendar, the true and astronomical Indian solar calendars, a generic lunisolar calendar that generalizes the Indian version, and the true and astronomical Indian lunisolar calendars. We also discuss aspects of the traditional Indian calculation of the time of sunrise and the determination of lunisolar holidays.
