For Varshitap, the traditional rule is:

• Start (Arambh): Chaitra Shukla Ashtami
• Parna (ending): Vaishakh Shukla Tritiya (Akshaya Tritiya)

For the year 2026, according to the Jain Panchang:

• Varshitap starts on: 9 March 2026 (Chaitra Shukla Ashtami)
• Parna is on: Akshaya Tritiya in April 2026 (Vaishakh Shukla Tritiya)

Because tithis can shift slightly by location (India / overseas, sunrise time, etc.), it is always best to confirm once with your local Jain Panchang or Upadhyaya before taking sankalp.
