Answer

A Jain Panchang is usually prepared by learned Jain scholars, monks, or traditional panchang-makers who understand:

• Jain calendar system

• Different traditions such as Śvetāmbara, Digambara, Sthānakavāsī, and Terāpanth

For example:

• Some Panchangs are prepared under the guidance of Jain monks or acharyas.
• Some are published by Jain sanghs, trusts, or religious institutions.
• Some are prepared by traditional jyotish or calendar scholars familiar with Jain dates.

• Paryushan and Das Lakshan
• Ayambil Oli
• Tirthankar kalyanak days

Takeaway

A Jain Panchang is made by knowledgeable Jain calendar experts and religious authorities, and it may vary slightly by sect, tradition, and region. For religious observances, one should follow the Panchang accepted by their own Jain sangh or guru-parampara.
