For Varshitap in 2026, as per the Jain (Vikram Samvat) lunisolar calendar:

• Varshitap starts on: Chaitra Shukla Ashtami
• In the Gregorian calendar for 2026, this corresponds to Thursday, 26 March 2026 (India).

This is the standard timing used so that the pārnā (completion) comes on Vaishakh Shukla Tritiya (Akshaya Tritiya), as per the traditional Varshitap maryādā.

Note: Some local sanghs or calendars may follow slightly different practical start dates, so it is always good to confirm once with your local Jain Panchang or sangh.
