• What it is: Deepawali for Jains is Mahavira Nirvana Divas — the day Lord Mahavira attained Moksha (nirvana) and illumination is celebrated in memory of his teachings.

• Date for 2025 (Gregorian): October 21, 2025. This is the Mahavira Nirvana Day observed by many Jain communities this year. Timings are linked to local sunset and night-time prayers, with lamps lit in homes and temples as part of the remembrance. ( faithvictoria.org.au)

• Timings and observances: In practice, Jains light clay lamps at dusk and perform special pujas, prayers, and readings in temples and at home. The exact schedule (when to begin, how long to stay up for night prayers, etc.) can vary by region and temple.

• Digambar vs. Shvetambar: Both traditions celebrate Mahavira Nirvana as the occasion for Deepawali, but there can be small regional or calendar-based differences in the exact date or ritual details. The core meaning remains the same: commemorating Mahavira’s Moksha and the spreading of his teachings. ( festivalsofindia.in)
