Jain

Your Home screen

Choose Jain as your community in Settings and the Home screen gives you:

• Everything in the panchang: tithi with paksha, lunar month, Adhik maas, sunrise and sunset, Choghadiya, Hora, Rahu Kaal, Abhijit muhurat and Panchak while it’s running.
• The 28 Jain nakshatras, which include Abhijit between Uttara Ashadha and Shravana.
• Navkarshi time each morning, worked out from your local sunrise.
• Sect-aware calendars for Shwetamber, Digamber, Khartargachh, Sthanakwasi and other traditions.
• A Today card with live sliders, as on the Hindu Home screen.

Everything is calculated on your phone from your location and the date, so the Jain Home screen works offline, including in a derasar or upashraya with no signal.

Why sect-aware calendars matter

Jain traditions share the same tirthankaras and the same core teaching, but they reckon the calendar in their own ways. Differences in how a lost (kshaya) or repeated (vriddhi) tithi is treated, or how an Adhik maas is counted, can place the same observance on different days. Paryushan and Samvatsari are the best-known example: different gachhs and sampradayas can observe them on different dates in the same year.

OIOA doesn’t choose between traditions. You pick the calendar your family follows, and the Home screen follows it. Jain sects and their calendars explains the differences respectfully, and if your sampradaya or gachh isn’t covered, please request it.

Tithi at the centre

For many Jain families, the tithi decides the rhythm of the month: Ashtami and Chaturdashi for fasting and observance, the five kalyanak days of each tirthankara, Ayambil Oli twice a year, and Paryushan. Most Jain calendars follow the tithi prevailing at sunrise, which is why OIOA calculates for your location. Read Jain tithi and the sunrise rule.

Navkarshi and daily practice

Navkarshi is the vow of not eating or drinking until 48 minutes after sunrise. Because sunrise changes every day and in every city, so does Navkarshi time. OIOA shows today’s Navkarshi for your location, so you don’t need a printed chart for another city. See Navkarshi explained.

The Jain calendar year

The Jain religious calendar counts years in the Vira Nirvana Samvat, from the nirvana of Bhagwan Mahavir, and its new year begins the day after Diwali, which marks that nirvana. Many Jain families also use Vikram Samvat. The Jain calendar explains both.

Days that matter

Our festival pages explain each occasion without publishing unverified dates:

• Paryushan
• Mahavir Janma Kalyanak

Set reminders for Ashtami, Chaturdashi, Ayambil Oli or any tithi you observe.

In your language

The Jain Home screen is available in Gujarati, Hindi, Marathi, Kannada and Tamil, and the other supported languages, as well as English. The EN ⇄ local-language toggle switches the whole page. See multi-language.

Shared with every community

You also get everything every community in OIOA shares: holidays and long weekends, the GST calculator, cards, family, groups, match-making, daily prediction and reminders.
