Short answer: Jains do not celebrate Dusshera in the way it is observed in Hinduism. Dusshera (Vijayadashami) is part of the Hindu festival cycle, while Jains follow their own annual holy periods focusing on self-purification, forgiveness, and vows.

What Jains celebrate instead:

• Paryushan Parva (Śvetāmbara Jains) or Das Lakṣaṇa Parva ( Digambara Jains): a sacred, monsoon-time period of intensive spiritual practice, fasting, study, and forgiveness. The culmination is Samvatsari (forgiveness day) in Śvetāmbara tradition or Kshamavani in Digambara tradition. You can read more here .
• Diwali is observed as a separate but related occasion in Jain tradition, often linked to remembrance of Mahavira’s teachings and a focus on inner light, not on victory over a mortal foe. See related Jain Knowledge content for context .

If you’d like a simple summary of the two main Jain observances (Paryushan and Das Lakṣaṇa Parva), I can outline their key practices and days.
