Answer

If you mean Das Lakshan Parva, it is a 10-day Jain observance that follows the lunar Jain calendar and begins on Bhadrapada Shukla Panchami and ends on Chaturdashi. ( calendar.ku.edu)

Explanation

For 2026, I found calendar listings that place it from September 15–25, 2026 in one source and September 16–25, 2026 in another. That difference happens because Jain festival dates are calculated by the lunar calendar and can vary slightly by tradition and locality. ( bhaktibharat.com)

Spiritual Understanding

Das Lakshan Parva is a sacred time for practicing the ten dharmas, self-purification, forgiveness, and inner discipline. ( jainfoundation.in)

Takeaway

So, in simple words: Das Lakshan Parva is around mid-September 2026, with the exact day depending on the Jain calendar followed in your community. ( bhaktibharat.com)
