In Jainism, Samvatsari is the most important festival day of the year for Shwetambar Jains, marking the culmination of Paryushan. Both Deravasi (those who worship in temples) and Sthanakvasi (those who do not worship in temples) are sects within the Shwetambar tradition, but sometimes they observe Paryushan and Samvatsari on slightly different days due to differences in calendar calculations.

For the year 2025:

• Deravasi Samvatsari is expected to be observed on Thursday, 28 August 2025.
• Sthanakvasi Samvatsari is expected to be observed on Wednesday, 27 August 2025.

Please note that these dates are based on traditional Jain calendars and may vary slightly depending on local customs and the lunar calendar. Always check with your local Jain community or temple for confirmation.
