Answer

I’m assuming you mean the Jain Solah Kāraṇ / Solahkāraṇ Vrat fast date.

The Solah Kāraṇ Vrat is traditionally observed during Paryushan / Das Lakshan period, especially in the Digambar Jain tradition. It is connected with reflection on the sixteen causes that lead to Tirthankar-nām-karma.

Important Note

The exact calendar date changes every year according to the Jain lunar calendar and also depends on tradition, region, and local sangh practice.

Please check your local Jain temple, sangh calendar, or Jain panchang for the exact date for your location and year.

Spiritual Understanding

Solah Kāraṇ Vrat is not only about fasting. Its deeper purpose is to cultivate qualities such as:

• right faith,
• devotion to Arihant and Siddha Bhagwan,
• discipline,
• compassion,
• purity of conduct,
• and spiritual aspiration.

Takeaway

For the exact Solah Kāraṇ fast date, follow the Jain panchang or your local Jain sangh, because the date may vary by year and place.
