Answer

According to the commonly followed Jain calendars for 2026:

• Dhanya Teras / Dhan Teras: Saturday, 7 November 2026
• Chaturdashi / Kali Chaudas: Sunday, 8 November 2026
• Amavasya / Diwali / Bhagwan Mahavir Nirvana Kalyanak: Monday, 9 November 2026

Nirvan Laddu will generally be celebrated/offered on:

Monday, 9 November 2026

Explanation

In Jain tradition, Diwali is especially sacred because it is connected with Bhagwan Mahavir Swami’s Nirvana Kalyanak. The Nirvan Laddu is offered in devotion to Bhagwan Mahavir on the Nirvana day.

For 2026, Jain calendars show:

• Aaso Vad 13 — Dhanya Teras — 7 November 2026
• Aaso Vad 14 — Chaturdashi / Kali Chaudas — 8 November 2026
• Aaso Vad Amavasya — Diwali / Mahavir Nirvana — 9 November 2026

Important Note

Some places may observe Diwali rituals on the evening of 8 November 2026, because Amavasya may begin then according to local panchang calculations. However, for Nirvan Laddu Puja, many Jain sanghs, especially Digambar traditions, observe it in the morning on 9 November 2026.

Takeaway

For Jain Nirvan Laddu in 2026, the date to follow is most likely:

Monday, 9 November 2026

It is best to confirm with your local Jain temple or sangh panchang, because tithi observance can vary slightly by location and tradition.
