What the tool shows
For the city and year you choose, the tool lists the civil day of Samvatsari on the two usual reckonings, the eight days of the Shvetambara Paryushan that end with it, the ten days of the Digambara Das Lakshana, and the day of Kshamavani. Where a tithi is lost between two sunrises or falls at two sunrises, it says so instead of choosing for you.
How the dates are found
Paryushan belongs to Bhadrapada, a lunar month, and to fixed tithis within it. The tool takes each civil day from late July to the end of October, finds the tithi current at that day’s sunrise in your city, and names the lunar month from the Sun’s sidereal sign at the new moon that began it. Bhadrapada Shukla 4 and Shukla 5 are then simply the days that carry those tithis.
- Shvetambara Murtipujak: Samvatsari on Bhadrapada Shukla 4. Paryushan is the eight days ending with it, so it begins seven days earlier.
- Many Sthanakvasi and Terapanth sanghs: Samvatsari on Bhadrapada Shukla 5, the day the tradition remembers as the older one. The Samvatsari page tells the history of the two dates.
- Digambara: Das Lakshana runs for ten days from Bhadrapada Shukla 5 to Shukla 14, and Kshamavani, the day of forgiveness, follows the day after the full moon.
The sunrise is the upper edge of the Sun at your city with the usual allowance for refraction, the same working that builds the pachkhan times by city. Because it is your city’s sunrise, a city far from India can sit a day away from the date printed in an Indian calendar.
When a tithi is lost or doubled
A tithi lasts between about nineteen and twenty-six hours. One can begin and end between two sunrises, so no day carries it, or it can cover two sunrises. The tool reports both cases plainly. In these years Shvetambara sanghs resolve the matter by their own rule, and Digambara calendars by another, so two sanghs in one city can keep a parva a day apart. The tool shows the astronomical result and leaves the choice to your own sangh, which is the right authority for a vow.
An adhika year
Some years carry an extra, adhika, month. When Bhadrapada is the doubled month, the tool gives the dates of the regular (nija) Bhadrapada and tells you so. How Paryushan is placed in an adhika year is decided by each sangh’s calendar, so check it before you fix the days.
How far to trust it
The dates agree with the Ahmedabad calendar tables on our Paryushana page for 2026 to 2030 and with Drik Panchang for the sunrise tithi. Treat the result as the astronomical day. Before you fix a vow, plan leave or book a hall, confirm the date with the published panchang of your own sangh. Where the traditions differ, none of them is wrong.
Frequently asked questions
↳ Why does the tool give two Samvatsari dates?
Most Shvetambara Murtipujak sanghs keep Samvatsari on Bhadrapada Shukla 4 and many Sthanakvasi and Terapanth sanghs keep Shukla 5. Both are old positions held in good faith, so the tool shows both days and leaves the choice to your sangh.
↳ Can the date differ from my sangh's calendar?
It can. The tool shows the astronomical tithi at your city's sunrise. Where a tithi is lost or doubled, sanghs follow their own rule, and a sangh's printed calendar is the authority for observance.
↳ Why is the date in my city different from India?
The tithi is read at the local sunrise. A city many time zones away reaches sunrise at a different moment in the tithi, so the same tithi can fall on a different civil day. The tool uses the sunrise of the city you choose.
↳ Is Das Lakshana the same as Paryushan?
No. Das Lakshana is the Digambara festival of ten days, from Bhadrapada Shukla 5 to Shukla 14, and the Shvetambara Paryushan is eight days ending with Samvatsari. They fall at about the same time and share the theme of forgiveness, but they are separate observances.
↳ How far ahead can I look?
The tool covers the years 1950 to 2074. Dates far in the future depend on the same astronomical formulae and are as reliable as the sunrise tithi; sangh calendars for those years do not yet exist.
