An Explanation of the Four Days of Chhath Puja: Nahay Khay, Kharna, Sandhya Arghya, and Usha Arghya

The Four-Day Journey of Devotion

Chhath Puja spans four days rather than just one, marked by rigorous discipline, profound purity, and steadfast devotion. Every day carries a unique name, particular rituals, and specific culinary customs.

Day 1: Nahay Khay (The Day of Purification)

The festival begins with Nahay Khay (literally "Bathe and Eat"). The Vrati (the individual observing the fast) takes a sacred dip in a river to cleanse both body and soul. The home is meticulously cleaned. The Vrati then eats one simple, pure vegetarian meal, typically made up of bottle gourd (kaddu) vegetable, chana dal, and rice prepared on a traditional clay stove.

Day 2: Kharna (The Day of Preparation)

The second day, Kharna, signifies the start of the strict fasting period. The Vrati fasts without water throughout the day. In the evening, a special prasad called Rasiyaw (kheer prepared with jaggery, milk, and rice) along with roti is made. After offering it privately to the deity, the Vrati eats it, commencing the 36-hour Nirjala (waterless) fast.

Day 3: Sandhya Arghya (The Evening Offering)

This day is the most visually stunning of the festival. Devotees arrange large bamboo baskets (daura) and soops loaded with fruits, thekua, sugarcane, and coconuts. In the late afternoon, the whole family goes to the edge of a river or pond. The Vrati stands waist-deep in the water and makes offerings Arghya toward the setting sun. This pays tribute to the setting sun (Pratyusha) and expresses gratitude for its life-giving energy.

Day 4: Usha Arghya (The Morning Offering)

Before daybreak on the last day, families gather once more at the riverbank. The Vrati stands in the water again, anticipating the sunrise. As the initial rays of the sun (Usha) emerge, the final Arghya The Vrati concludes their 36-hour fast by taking ginger and water, signifying the successful end of the Chhath Puja.
