Chhath Puja, a significant festival primarily celebrated in Bihar and other parts of North India, particularly by the Bihari diaspora worldwide, is dedicated to the Sun God (Surya) and his wife, Usha.

Chhath Puja is all about showing gratitude to Lord Surya for providing life and light to all the living beings. Chhathi Maiya bestow the devotees with good good fortune, good health, prosperity and success.
