Answer

“Do Tithi” tradition generally means the Jain practice of observing a religious activity according to the Tithi—the lunar date—rather than only the English calendar date.

In Jain Dharma, many important observances are based on Tithi, such as:

• Chaudas
• Atham
• Pakhi
• Paryushan / Das Lakshan days
• Mahavir Janma Kalyanak
• Samvatsari
• Aayambil Oli

Explanation

A Tithi is a lunar day, calculated according to the position of the Moon. Because Jain rituals and festivals traditionally follow the lunar calendar, the exact English date may change every year.

“Do Tithi” may also refer to situations where there are two Tithis connected with one observance, or where different Jain communities follow slightly different calendar calculations. In such cases, people generally follow the calendar and guidance of their own Jain sangh, gacch, sampraday, or guru-parampara.

Spiritual Understanding

The purpose of following Tithi is not merely calendar accuracy. It helps a Jain devotee live in rhythm with traditional religious discipline through:

• Upvas or other tapasya
• Samayik
• Pratikraman
• Swadhyay
• Bhavna and inner purification

Takeaway

In Jain Dharma, Tithi-based observance is a traditional way to preserve religious discipline. If there is confusion about “Do Tithi,” it is best to follow the decision of your local Jain sangh or guru-parampara.
