For Varshi Tap in 2026, the start tithi is:

• Chaitra Shukla Ashtami (8th day of the bright half of Chaitra)
• It always ends on Vaishakh Shukla Tritiya (Akshay Tritiya)

The exact English (Gregorian) date for Chaitra Shukla Ashtami in 2026 depends on the Jain Panchang (it can differ slightly by city and by Panchang), so for a precise start date you should:

• Check a Jain Panchang / Jain calendar for 2026 for your city/sect, or
• Ask your local Jain temple / Pathshala.
