Answer

If you mean Śvetāmbara Paryushan, it is generally listed as starting on 28 August 2027 and ending on 4 September 2027, with Samvatsari on 4 September 2027. Some calendars list the start one day later, on 29 August 2027, so the exact date can vary slightly by panchang and region. ( faithvictoria.org.au)
