Posh Dashamī (Poṣa‑daśamī) is the Poṣha/Māgsar month’s tenth day and is celebrated as Parśvanātha‑jayantī. The exact tithi can vary by region and lunar sighting, and Digambar vs. Śvetāmbara calendars may have slight differences. In 2025, the commonly cited date is around December 14, 2025 (Vad Dashamī), but some Panchangs may shift by a day depending on local calculations. Always check your temple’s regional Jain Panchang for the precise day. You can read more here and here .

Notes:

• Digambar and Śvetāmbara communities may have small differences in the exact tithi in a given locality, but the festival’s essence remains Parśvanātha‑jayantī.
• If you tell me your city or temple, I can confirm the exact Gregorian date for that year from your local Jain Panchang.
