In Jainism, the 24 Tirthankaras are greatly revered, and their lives and teachings are celebrated, especially during certain festivals and rituals. However, Jain scriptures do not assign each Tirthankara to a specific day of the month in a systematic or universal way for daily worship. Instead, the following practices are observed:

1. Mahavir Jayanti: This festival celebrates the birth of Lord Mahavira, the 24th Tirthankara, on the 13th day of the bright half of the month of Chaitra (March-April).

1. Paryushana and Das Lakshana: During these most important Jain festivals, all Tirthankaras are remembered and worshipped, with special emphasis on their teachings.

1. Snatra Puja and Panch Kalyanak Puja: These rituals often include the worship of all 24 Tirthankaras by reciting their names and narrating their five auspicious life events (Kalyanaks).

1. Chauvishi: Some Jains perform a daily or periodic worship called "Chauvishi," in which all 24 Tirthankaras are venerated collectively, sometimes with a lamp or through recitation, but not assigned to specific dates in a month.

There are illustrated charts and recitations (such as the "Chaturvimshati Stava") listing the names and symbols of all 24 Tirthankaras, but these do not correspond to a specific calendar schedule for each Tirthankara.

In summary: Jain tradition does not assign each of the 24 Tirthankaras to a particular day of the month for worship. Instead, all Tirthankaras are honored collectively during major festivals, rituals, and daily prayers.
