[2] The solar month is significant because it inspires the name of the 12-year cycled Kumbha Mela, where Hindu pilgrims gather by tens of millions to one of four pilgrimage sites, in the weeks before it starts.
[7] The Kumbha month is called Masi in the Tamil Hindu calendar.
[1] The ancient and medieval era Sanskrit texts of India vary in their calculations about the duration of Kumbha, just like they do with other months.
For example, the Surya Siddhanta calculates the duration of Kumbha to be 29 days, 19 hours, 41 minutes and 12 seconds.
[6] In contrast, the Arya Siddhanta calculates the duration of the Kumbha month to be 29 days, 19 hours, 24 minutes and 0 seconds.
