Ashtapad Oli Ji likely refers to Navpad Oli (Ayambil Oli), the important Jain festival of nine days honoring the Navpad (nine supreme virtues). Here is the core significance in simple terms:

• What it is

- Navpad Oli Ayambil Oli is a twice-yearly, nine-day spiritual observance. During these nine days, Jains perform Ayambil (a simple, one-meal-a-day fast) and worship the Navpad or Siddhachakra—the nine supreme posts in the universe. The key aim is inner purification and strengthening three jewels: right faith, right knowledge, and right conduct. You can read more here and here .

• The nine Navpad (the nine posts)

- Arihant, Siddha, Acharya, Upadhyaya, Sadhu/Sadhvi, Samyak Darshan, Samyak Gyan, Samyak Charitra, Samyak Tap. Each day of the Oli is devoted to one Navpad, with puja, prayers, and reflections centered on that aspect. This structured focus helps purify passions, deepen detachment from taste, and cultivate virtues. See explanations of the Navpad concepts here and here .

• When it occurs

- It happens twice every year: in the bright half of Chaitra (around March–April) and in the bright half of Ashwin (around September–October). Exact dates vary by local calendar, so communities follow their sangh/panchang. For current year planning, see the general guidance here .

• Digambar vs. Shwetambar notes

- Both Digambar and Shwetambar traditions honor Navpad Oli, but the liturgical emphasis can differ slightly: Shwetambar often centers on Siddhachakra worship during Navpad Oli, while Digambar communities may emphasize Navpad Aradhana with slight differences in practice. The spiritual aim remains the same: purification and reverence to the Navpad for Moksha.

• Essence in one line

- Navpad Oli is a disciplined, two-times-a-year nine-day practice of simple eating, prayer, and Navpad worship to purify the mind and strengthen commitment to the three jewels.
