Here are the major Jain pilgrim festivals you typically find at Palitana (Shatrunjaya) in Gujarat:

• Kartik Purnima (Shri Shantrunjay Teerth Yatra)

- Thousands of Jains come to Palitana to begin or continue the reverent yatra up the hill on the full moon of Kartik. It’s one of the biggest pilgrim days at Shatrunjaya. This is a key event for both Śvetāmbara and Digambara Jains. You can read more about Kartik Purnima and its Palitana connection.

• Chha Gau Teerth Yatra (Fagun Sud Teras / 6 Gaon Yatra)

- A very large pilgrimage day in February/March when pilgrims circumambulate Shatrunjaya in a 15–18 km walk (often called “6 Gaon”). It is a distinguished event at Palitana Mahatirth and draws lakhs of devotees. There are detailed notes about Fagun Sud Teras and 6 Gaon on Palitana’s Pilgrim traditions.

• Mahavir Janma Kalyanak (Mahavir Jayanti)

- The birth anniversary of Lord Mahavir. Palitana’s Shatrunjaya temples host grand darshan, processions, and special pujas. Observance is common to both Śvetāmbara and Digambara communities with temple rites and fasting as typical features. See notes on Palitana’s festival observances.

• Paryushana Parva and Samvatsari (Forgiveness Day)

- One of the most important Jain retreats, focused on self-purification, fasting, prayers, and forgiveness. Palitana’s temples participate with pravachan, tapas, and community prayers; both major Jain divisions observe it. You can find general context about Paryushana in Jain sources.

• Navanu Jatra (Navanu Yatra)

- A renowned 99-fold pilgrimage to Shatrunjaya, undertaken by many devout Jains as a challenging spiritual practice. It is widely associated with Palitana and is often undertaken by seasoned pilgrims visiting Shatrunjaya. Details are available in Palitana pilgrimage literature.

• Adinath Salgira (Mulnayak consecration anniversary)

- The anniversary celebration of the main idol (Mulnayak) of Adinath at Shatrunjaya. This event attracts pilgrims for special pujas and darshan. Dates vary by lunar calendar each year.

Notes on tradition and differences:

• The above festivals are observed by both Śvetāmbara and Digambara Jains in Palitana, though ritual details can vary slightly between traditions. The core spirit—darshan, austerity, and devotion at Shatrunjaya—is shared.
• Palitana temples sit on Shatrunjaya hill; pilgrims typically climb the 3,500–3,800+ steps with a focus on silence and reverence during darshan.
