Chaitri Poonam, also known as Chaitra Purnima, is an auspicious day in the Jain calendar. It falls on the full moon day (Purnima) of the month of Chaitra (March-April). This day holds special significance for Jains due to several reasons:

1. Religious Significance:

Chaitri Poonam is celebrated as the day when Lord Shantinath, the 16th Tirthankara, attained kevalgyan (omniscience). Many Jain texts mention this as a day of spiritual upliftment and increased merit for religious activities.

1. Pilgrimage to Shatrunjay:

One of the most important traditions associated with Chaitri Poonam is the grand pilgrimage (yatra) to the sacred Shatrunjay hill in Palitana, Gujarat. This is considered the last and most significant organized yatra of the year. Thousands of Jains climb the hill and visit the Shatrunjay temples to offer prayers and perform rituals.

1. Merit of Religious Activities:

On Chaitri Poonam, it is believed that engaging in acts of devotion, fasting, charity, and listening to scriptures yields special spiritual merit (punya).

1. End of Chaturmas Yatras:

In many Jain communities, this marks the culmination of the annual cycle of temple pilgrimages and religious observances that begin with Kartik Poonam.

1. Cultural Bonding:

The day is also celebrated as a time for Jain communities to come together for collective worship, processions, and spiritual discourses.

In summary: Chaitri Poonam is important in Jainism due to its association with Lord Shantinath’s kevalgyan, the large-scale pilgrimage to Shatrunjay, and the belief that religious observances on this day are especially meritorious. It is a day of devotion, celebration, and spiritual reflection for Jains.
