In Jain Dharma, days of the week are not officially fixed for any particular “Jain gods” in our scriptures.

1. No scriptural rule

- In the Agams and main Jain texts, there is no system like: “Monday = this Tirthankar, Tuesday = that dev,” etc. - Any Tirthankar or Panch Parmeshti can be worshipped on any day.

1. What actually happens in practice

- In many Jain families and derasars, people personally choose one Tirthankar or dev-devi for a certain day (for puja, jaap, upvaas, etc.). - These choices are usually local custom or family tradition, not a universal Jain rule. - Because they are local customs, the list of “Monday = X, Tuesday = Y …” can change from city to city or even from one sangh to another.

1. Important Jain view

- Jain Dharma mainly teaches us to focus on: - Panch Parmeshti (Arihant, Siddha, Acharya, Upadhyay, Sādhu) - 24 Tirthankars - The real aim is right faith, right knowledge, right conduct – not planetary or weekday-based worship.

So, strictly speaking:

• No fixed, pan-Jain list exists in authentic Jain shastra.
• Any such weekday–dev list you see is just a devotional habit, not a Jain doctrinal requirement.
