Posh Dashami (Poṣa‑daśamī) in 2025

• Date: commonly around December 14, 2025 (Vad Dashami). Some Panchangs may show a one-day variation depending on local lunar sighting.
• Tradition: Poṣa‑daśamī is the birth anniversary of Parśvanātha and is observed in the Poṣha/Māgsar period. Digambar and Śvetambar calendars may differ slightly on the exact day, but the observance centers on Poṣha‑daśamī.
• Ekadashi: Jain observances alternate from Dashami (Poṣha‑daśamī) and do not correspond to the ordinary Ekadashi dates used in other calendars; if you’re looking for an Ekadashi-specific Jain observance, please specify a region or temple, as dates can vary by local panchang.
