For this (Vikram Samvat 2082–83) cycle:

• Varshitap in 2026 starts on:

Chaitra Shukla Ashtami (8th day of bright half of Chaitra)

• It ends (Parna) on:

Vaishakh Shukla Tritiya (Akshaya Tritiya) – in 2026 this is Monday, 20 April 2026.

Because Varshitap follows the Jain lunar calendar, the exact English date for Chaitra Shukla Ashtami can vary slightly by location and panchang. For this year, different Jain calendars show it around 9–10 March 2026 (many list Tuesday, 10‑03‑2026 as Varshitap start). ( jaindharmonline.com)

So in simple form:

• Tithi rule (authoritative):

Start: Chaitra Shukla 8 End (Parna): Vaishakh Shukla 3 (Akshaya Tritiya)

To be 100% sure for your city and sangh, please check your local Jain panchang or ask your guru/temple, and follow the date they announce.
