Varshitap usually begins on Fagan Vad Satam in the Jain calendar. In the verified calendars I found, it started on 21 March 2025 and 10 March 2026. Based on that yearly lunar shift, the 2027 start would most likely fall around late February 2027 — approximately 27 February 2027. This is an inference, so for the exact day in your local panchang, please follow your community’s Jain calendar. ( oshwal.org.uk)
