Short answer: In Jain Dharma, there is no standard, canonical practice of “Ghria Pravesh” (house-entry ceremony) on Posh Dashmi. Dashami-related rituals in Jainism are not tied to the Hindu custom of Griha Pravesh, and Jain rituals focus on tirthankar puja, samayik, mutta upvas, and other Jain-specific observances rather than this house-entry ritual.

If a particular Jain community or family observes a Ghria Pravesh on Posh Dashmi in 2025, it would be a local or family tradition rather than a universal Jain practice. For exact dates and local customs, please consult your local Jain priest or an authoritative Jain calendar for your sampatti (sect and region).

If you’d like, I can look up JainKnowledge.com pages that discuss Dashmi, Posh month observances, or house-related rituals in Jain practice and point you to them.
