In Digambar Jainism, Micchhami Dukkadam is exchanged on the forgiveness day of the Das Lakshana Parva, i.e., the Kshama (forgiveness) day that opens the 10-day Das Lakshana period. This is on the first day of Ashvin Krishna (the Digambar calendar’s Das Lakshana Parva).

Key point:

• When: on the first day of Ashvin Krishna (Kshamavani Parva) in Digambar practice.
• Purpose: seek and grant forgiveness, start the vow-filled Das Lakshana period.

Note: The exact Gregorian date changes each year. For 2025, it falls around late August (Kshamavani on 24 August 2025). You can read more here
