Posh Dashmi (Poṣa‑daśamī) is a Jain festival observed on the tenth day of the Poṣha/Māgsar period in the Jain calendar. It is traditionally associated with the life and worship of Parshvanath, the 23rd Tirthankar. The observance often spans a few days (9th, 10th, and 11th of the dark half of Poṣha/Māgsar) and includes temple visits, Navkar mantra recitation, sermons about Parshvanath, and devotional rituals. The exact date varies each year by region and lunar sighting, so local panchangs or your temple calendar should be checked for the precise day. Digambar and Śvetambar calendars may differ slightly in the tithi, but the spiritual aim remains to honor Parshvanath and practice self-discipline.

• Core purpose: remembrance of Parshvanath and fostering restraint, reflection, and spiritual progress.
• Common practices: temple puja, listening to Parshvanath’s story, Navkar mantra recitation, meditative reflection, and sometimes ekasanas (restricted meals) on the days of the observance.
