I'm pretty much aware of Shravan Maas, we don't eat non-veg and alcohol; some people don't even shave but why there is a gap of 15 days in Shravan Maas of North Indians and Maharashtrians?

  • What do you mean by a gap? Commented Jul 17, 2014 at 8:30

    @KeshavSrinivasan I think he means that if North Indian starts Shravan Maas say today, than Maharashtrians start after 15 days or vice versa...

1 Answer 1


Each Hindu month consists of one full lunar cycle, either from full moon to full moon, or new moon to new moon, which would be ~ 28 days. The period from the Purnima to Amavasya takes ~14 days, and is called the Shukla-paksha, or the bright half of the month. From the Amavasya to Purnima is another 14 days, which is called the Krishna-paksha, or the dark half of the month.

North Indians follow the Purnimant calendar, ie, the month begins with the Purnima or the full moon, till the next full moon. In the North Indian calendar, the Shukla-paksha of the month comes first, followed by the krishna-paksha. Maharashtrians & South Indians follow an Amavasyant calendar, ie, the month begins from Amavasya or the New Moon, where the krishna-paksha comes first, followed by the shukla-paksha.

  • Valarko - Krishna paksh is the fortnight with fading moon ie.. from Poornima to Amavasya. Shukla paksh is fortnight with brightening moon ie.. from Amavasya to Poornima

  • You stated wrong. North indians follow Purnimanta- the month starts from krishna paksha and ends on sukhla paksha. & south indians follow Amanta- the month starts on purnima & ends on Amavasya. You stated exactly oppposite. Commented Jul 11, 2022 at 5:45
