In Jain Dharma, the days of the week are not originally “assigned” to any God or Tirthankara in the way you may hear in Hindu or astrological traditions (e.g., Monday–Shiv, Tuesday–Hanuman, etc.).

1. Scriptural / doctrinal point (pure Jain view)

• Jain āgams and tattva-granthas do not say:

- “This weekday belongs to this Dev or this Tirthankara.”

• Time (kāl) is seen as beginningless, endless and neutral – no day is “lucky” or “unlucky” by itself.
• Any day is good for:

- samayik, pratikraman - svādhyāy (study), dhyān (meditation) - tapas (fasting), dān (charity)

So from a pure Jain philosophical standpoint, no God is the owner of any weekday. The focus is on your inner state, not the calendar label.

2. Popular Jain practice (social/custom level)

Over time, living among other Indian traditions, some Jain communities adopted a devotional pattern of remembering certain Tirthankaras more prominently on certain weekdays. This is custom, not scripture.

A commonly seen pattern is:

• Sunday – Shri Rishabhdev (Adinath)
• Monday – Shri Ajitnath
• Tuesday – Shri Sambhavnath
• Wednesday – Shri Abhinandan Swami
• Thursday – Shri Sumatinath
• Friday – Shri Padmaprabhu
• Saturday – Shri Suparshvanath

People may:

• do upvās or olī-style fasts on a fixed weekday
• recite a particular stotra of that Tirthankara
• sponsor pooja/abhishek in that Tirthankara’s name that day

But again, this is a bhakti-based habit, not a Jain “rule” of time or planets.

3. Difference from planetary / astrological assignment

Outside Jainism, days are often tied to planets and gods (Ravi–Sun, Som–Moon, etc.). In Jain view:

• Such grah ideas are not central to liberation (moksha).
• Where you see “Navgrah” in Jain temples, it usually means nine supreme beings/virtues (Arihant, Siddha, Acharya, etc.), not nine physical planets.

4. Simple takeaway

• No weekday is fixed to any God or Tirthankara in core Jain scriptures.
• Some Jains choose to link certain days with certain Tirthankaras for convenience in bhakti.
• From the standpoint of moksha, every day, every moment becomes “special” when filled with right faith, right knowledge, and right conduct (samyak darshan–jnan–charitra).
