In Jainism there is no original scriptural system that says:

• “Wednesday is for Shantinath,”
• “Saturday is for Munisuvrat Swami,” etc.

That kind of “day–devta” logic (like in Hinduism: Tuesday–Hanuman, Thursday–Guru, Saturday–Shani) is not found in Jain Agams or main Jain shastras.

What actually happens is:

1. Scripturally

- Any Tirthankar can be worshipped on any day. - Important are their kalyanak days (janma, keval‑jnan, nirvan), tithis, and major festivals, not the weekday name.

1. Devotional / Local customs

Over time, some Jain communities (both Śvetāmbara and Digambar in different regions) adopted a “days of week” practice for convenience and bhakti, by roughly lining up: - Sunday – Adinath - Monday – Ajitnath - Tuesday – Sambhavnath - Wednesday – Abhinandan Swami (in many traditions) - Thursday – Sumatinath - Friday – Padmaprabhu - Saturday – Suparshvanath This pattern (1st–7th Tirthankars mapped to Sunday–Saturday) is one commonly seen tradition, but it is not scriptural and not fully uniform everywhere.

1. Why you hear things like “Saturday = Munisuvrat Swami” or “Wednesday = Shantinath”

- These are usually regional bhakti practices, family traditions, or vrat customs. - For example, in some areas devotees specially fast or do puja to Munisuvrat Swami on Saturday, so locally people begin to say “Saturday is for Munisuvrat.” ( jainknowledge.com) - Similarly, some people may choose Shantinath on a particular weekday (like Wednesday) because they have personal faith in him for shanti, health, or specific vows. - But these assignments are not the same everywhere and not based on Agam command.

1. Digambar vs Śvetāmbara

- On this specific matter (weekday–Tirthankar mapping), neither tradition has a canonical rule. - Differences you see are mostly community / temple / family customs, not doctrinal differences of the sects.

1. Essence according to Jain Dharma

- From a pure Jain point of view, it is best to understand: - Weekdays have no inherent spiritual power. - Shuddha bhakti, samyak darshan, and following the vows (vrat) are what purify karma, not the label of the day. - You may follow your family’s or local sangh’s practice for convenience and emotional connection, but remember it is optional upchar (devotional form), not a compulsory Jain rule.
