Vira Nirvana Samvat Converter: Any Date to the Jain Year

Vira Nirvana Samvat (VNS) is the Jain era, counted from the night Bhagwan Mahavira attained nirvana at Pavapuri. Choose a date and your city and this tool gives the VNS year for that date, the Vikram Samvat year in the Kartika reckoning Gujarati calendars use, the tithi at sunrise and the date of the next Jain new year. Or type a VNS year to see the first and last day it covers.

For Ahmedabad the tool gives the start of Vira Nirvana Samvat 2553 as Tuesday 10 November 2026 and of 2554 as Saturday 30 October 2027, the days our Diwali and Vira Nirvana page gives.

How it works

The convention we follow. Our Diwali and Vira Nirvana page sets it out: the epoch is Kartika Amavasya, 527 BCE by the traditional reckoning, and the year number turns at the first sunrise of Kartika Shukla 1, so the Jain new year, not Chaitra, is when VNS changes. From that day to 31 December, VNS is the Common Era year plus 527; from 1 January to the day before the new year it is plus 526. Vikram Samvat counted from Kartika, as Gujarati calendars count it, turns on the same day, so in that count VNS is always VS plus 470.

Finding the new year. For the year of your date the tool reads the tithi at sunrise in your city day by day through October and November, names the lunar month the amanta way (from the Sun’s sidereal sign at the new moon that began it), and takes the first civil day whose sunrise falls in Kartika. That is usually the day after Diwali, but not always: in 2026 Amavasya was still current at sunrise on 9 November in Ahmedabad, so the new year was 10 November.

The source of the 527 BCE count. Our Diwali page gives 527 BCE as the tradition’s own epoch. The Wikipedia article on the era names Yativrishabha’s Tiloya-Pannatti as the earliest text to state it (citing Kailash Chand Jain and Paul Dundas), and Jinasena’s Harivamsha of 783 CE as putting the nirvana 605 years, 5 months and 10 days before the Shaka era (citing D. C. Sircar’s Indian Epigraphy).

Checked. The new year day was compared with an independent Swiss Ephemeris calculation of the first sunrise of Kartika Shukla for each year from 1899 to 2075 at four test places (Mumbai, Lautoka, London and New York) and from 2000 to 2035 at four more, 852 place-years, and agreed in every one. The year given for the birth date of each of our eight test charts, and for the days either side of that year’s new year, 32 dates in all, agreed as well.

Reading the result

The first line gives the VNS year for your date, the day that year began in your city and the day it ends, and the Vikram Samvat year. The cards repeat these with the tithi at sunrise and the number of days to the next Jain new year. If you typed a VNS year instead, you see its first and last civil day and its length.

Where traditions differ

• The epoch. The era in use counts from 527 BCE. Paul Dundas (The Jains, 2002, p. 24, as cited in the Wikipedia article on Mahavira) gives 527 BCE as the Shvetambara date and 510 BCE as a Digambara one, and suggests the nirvana may in fact fall around 425 BCE; historians working from Hemachandra’s Parishishtaparvan have proposed 477 or about 468 to 467 BCE, as the same article cites. These change the history, not the count printed in Jain calendars, so the tool shows the count in use.
• The day the year turns. We turn the year at the first sunrise of Kartika Shukla. Some calendars and lists turn it on the day after Diwali, which is usually the same day; in a year like 2026 they differ by one day.
• Vikram Samvat. Gujarati calendars count Vikram Samvat from Kartika, the same day as VNS. In North India it is counted from Chaitra Shukla 1, about seven months earlier, and from then until the Jain new year that count reads one more than the Kartika count.
• 469 or 470. The Wikipedia article on the era says VNS is obtained “by adding 469 or 470 years to the Kartikadi Vikram Samvat”, and further on that the difference is 469 years until Kartik Shukla 1 and 470 after it, which is how the Chaitra count behaves. With our convention both VNS and the Kartika count turn at the Jain new year, so the difference from the Kartika count is 470 all year; from the Chaitra count it is 469 between Chaitra Shukla 1 and the Jain new year and 470 for the rest of the year.

What it does not do

It does not date historical events, which carry the uncertainty described above. It gives the civil day by the sunrise rule; where your sangh’s calendar differs, follow the calendar. Dates before 1900 and after 2074 are not offered, because the day-by-day calendar behind the tool is checked only for those years.
