Chaitra Purnima is the full moon day in the month of Chaitra (March–April) and is considered highly auspicious in the Hindu calendar. It is a time for spiritual purification, charity, and devotion, marking the conclusion of the Chaitra Navaratri in some regions and the birth anniversary of Shri Hanuman in others.

On this day, devotees wake up early, take a holy bath, especially in rivers or sacred water bodies, and perform puja to Lord Vishnu, Hanuman, or Chandra Deva (Moon God). The Satyanarayan Puja is very popular on this day. Devotees clean the puja area, install Lord Vishnu’s image, and perform rituals with turmeric, sandal paste, flowers, incense, fruits, and sweets.

The Satyanarayan Katha is read, and prasad made from rava, banana, sugar, and ghee is offered. The Vishnu Sahasranama, Hanuman Chalisa, and Gayatri Mantra are commonly chanted. Fasting is observed by many devotees, often concluding after moonrise.

Worship of the full moon (Purnima Chandra Puja) is also done in the evening, offering water (arghya), white flowers, and rice mixed with milk, praying for peace, mental strength, and emotional balance.

Another important aspect of this day is charity (dana)—devotees donate food, clothes, or money to Brahmins or the needy. In some temples, annadanam (mass feeding) is organized.

Chaitra Purnima is considered a highly spiritual day that purifies the mind and body, bestows good fortune, fulfills desires, and removes past karmic burdens. It is an ideal day for introspection, meditation, and devotion to the Divine.
