The Gregorian calendar is used alongside the national Indian calendar. Like the solar calendar, the Indian calendar has tweleve months. There used to be dozens and dozens of Indian calendars all centered around each region’s religious festivals. Luckily, now there is only one standard Indian calendar. I have the Indian month which corresponds to a Gregorian month, so that you have some idea of when the Indian months take place.
