In Jainism, "Badi Teras" (also known as "Vadi Teras" or "Vad Teras") refers to the thirteenth day of the dark half (Krishna Paksha) of a lunar month, according to the Jain calendar. Many important Jain spiritual events and anniversaries (such as the Nirvana or significant life events of Acharyas and saints) are observed on specific Tithis (lunar days) like Badi Teras.

Bhikshu Swami Badi Teras specifically refers to the day commemorating the Nirvana (liberation) or significant event of Acharya Bhikshu Swami, the founder of the Terapanthi sect in Śvetāmbara Jainism. According to Jain tradition, this falls on the Badi Teras of the month of Jeth (Jyeshtha) in the Jain calendar, which typically occurs in May or June according to the Gregorian calendar.

The exact Gregorian date varies each year because the Jain calendar is lunar-based. In 2024, Jeth Badi Teras falls on June 2, 2024.

On this day, Terapanthi Jains remember the teachings and contributions of Acharya Bhikshu Swami through prayers, scriptural readings, and special gatherings.

Summary: Bhikshu Swami Badi Teras is observed on Jeth Badi Teras (thirteenth day of the waning moon of Jeth), which is June 2, 2024, and is significant for followers of the Terapanthi Jain sect.
