In Jain tradition, Chaturmas is the four-month period of vows and penance during the monsoon. For 2026, Sangh calendars usually place the start in late July and end in late November, with exact dates varying a bit by local tirth/sangh arrangements. A commonly noted pattern for 2026 is a July–November window, beginning around the Ashadha Shukla Ekadashi (Devshayani Ekadashi) and ending near Kartik Shukla Ekadashi. In many places the start is around July 25, 2026 and the end around late November 2026, though local calendars may shift by a day or two. You may find local thana schedules announced by the tirth authorities for that year.

Notes:

• If you want the exact dates for your local Jain sangh or tirth in 2026, please check their official announcements, as the start and end can differ slightly by community.
