Answer

In many Jain calendars, Chausmasa/Chaturmas begins on Ashadha Shukla Ekadashi. For 2026, that falls on Saturday, 25 July 2026. Some local Jain sanghs follow slightly different panchangs, so the exact start can vary a little by tradition and region. ( jainknowledge.com)

Explanation

Chausmasa is the rainy-season retreat in Jain Dharma, when monks and nuns stay in one place and lay followers often increase study, vows, and spiritual practice. ( jainknowledge.com)

Takeaway

If you mean the 2026 start date, use 25 July 2026 as the common reference, and check your local sangh calendar if you follow a specific tradition. ( jainknowledge.com)
