Poṣa‑daśamī (Posh Dashami) is the birth anniversary of Parśvanātha and is observed in the month of Māgsar/Posh depending on regional panchang. In 2025, the exact Poṣa‑daśamī date varies by local calendar and region (some places observe it in late December 2025, others in early January 2026). For your locality, check your temple’s calendar or the regional Jain panchang to confirm the precise date. ( jainknowledge.com)

Key point:

• Poṣa‑daśamī is typically celebrated on the tenth day of the Poṣha/Māgsar cycle, and rituals can span multiple days depending on tradition. However, the 2025 date is not fixed nationally and must be confirmed locally. ( jainpedia.org)
