Paryushana (often spelled Padushan) is one of the most important annual festivals in Jainism. The exact dates vary each year because the Jain calendar is lunisolar.

For Svetambara Jains, Paryushana usually begins on the 12th day of the waning moon (Krishna Paksha) in the month of Bhadrapada (August or September), and lasts for 8 days.

For Digambara Jains, the festival is called Das Lakshan Parva and starts usually a day later, lasting for 10 days.

For the year 2024, Paryushana for Svetambaras is likely to start around August 28, 2024, and for Digambaras, Das Lakshan Parva will begin around August 29, 2024. However, these dates might slightly vary depending on local calendars and traditions, so it is always best to confirm with your local Jain temple or community.

If you need the exact date for your location or sect, please consult your local Jain Sangh or temple.
