In Jain tradition, for Tirthankar Bhagwans we mainly record:

• Maas (month – e.g. Chaitra, Vaishakh, etc.)
• Paksh (Shukla / Krishna)
• Tithi (lunar date – e.g. 13th, 14th, Poonam, Amas)
• Kalyanak (Garbh, Janma, Diksha, Kevaljnan, Nirvan)
• Nagri / place (Ayodhya, Kundalpur, etc.)

The day of the week (Sunday, Monday, etc.) is generally not given in the original Jain scriptures for the 24 Tirthankars.

So:

• There is no single, authentic “list of weekdays” for all 24 Tirthankars’ births in the core Agams / canonical texts.
• Different modern Jain calendars may calculate weekdays using astronomy, but these are later calculations, not a standard scriptural list.
• Both Śvetāmbara and Digambara traditions focus on tithi and month, not on weekday.

Because of this, a precise “week‑day list” (Sunday to Saturday for each of the 24) cannot be given as a strictly scriptural Jain list.
