Chhath Puja has no idol to dress, no temple to visit and no priest to guide the family. Its whole strength comes from purity. One careless mistake in the kitchen or at the ghat is believed to weaken the vrat, which is why families in Bihar and eastern Uttar Pradesh follow the rules with almost military discipline.The festival runs from Friday 13 November to Monday 16 November 2026. Sandhya Arghya falls on Sunday evening and Usha Arghya at sunrise on Monday. These are the seven purity rules every household should know before the main days.
1. Keep the Kitchen Sattvic from Day One
From Nahay Khay onwards, onion, garlic, meat, fish and eggs leave the house completely. That applies to the whole family, not only the vrati. Many homes also stop using regular salt and cook with rock salt. Prasad is ideally made on a new or freshly cleaned clay stove, using mango wood as fuel. Utensils used for daily cooking stay aside. Brass, bronze or new steel vessels are kept only for the festival.
2. Never Taste the Prasad While Cooking
This rule catches many first-timers. Thekua, kheer and laddoos are made for Surya and Chhathi Maiya, so nobody tastes them during preparation, not even a pinch to check the sweetness. Food that has been tasted is considered jutha and cannot be offered. The cook should wash their hands often and avoid touching their face or hair while handling the prasad.
3. Respect the Vrati’s Space
The person keeping the fast follows strict personal rules. Traditionally the vrati sleeps on the floor on a mat or blanket, not on a bed, for the four days. Fresh, unstitched clothes are preferred. Women often wear a cotton saree and men a dhoti. Family members should not touch the vrati’s belongings, puja items or bedding with unwashed hands. And arguments or harsh words around the vrati are strongly avoided, since peace of mind is treated as part of the purity.
4. Choose Offerings with Care
Everything in the soop should be fresh, whole and unbroken. Bruised fruit, cracked coconuts or a broken sugarcane stalk should not be used. Bamboo baskets and soops should be new or properly washed and dried. Some families avoid steel and plastic altogether for the offerings, keeping to bamboo, brass and clay.
5. Don’t Miss the Arghya Moment
Timing matters as much as cleanliness. On Sunday 15 November, sunset falls around 4:53 PM in Kolkata, 5:01 PM in Patna, 5:28 PM in Delhi and 6:00 PM in Mumbai. On Monday 16 November, sunrise comes at about 5:50 AM, 6:07 AM, 6:44 AM and 6:46 AM in those cities. Leave home early enough to settle in at the ghat with time to spare. If you arrive after sunset, the evening offering cannot be done properly.
6. Keep the Ghat Clean
Purity does not end at your own doorstep. Plastic bags, synthetic decorations and chemical colours have no place near the water. Use flowers, diyas and leaf plates that break down naturally. After the arghya, collect your leftover items instead of leaving them on the riverbank. A dirty ghat goes against the very idea of honouring nature’s life-giving force.
7. Break the Fast the Right Way
After the Usha Arghya on Monday, the vrati should not eat a heavy meal straight away. The usual practice is to start with prasad, a little ginger and some water. Light food comes a little later. After 36 hours without water, the body needs to be eased back in gently. Elderly vratis, and anyone with diabetes, blood pressure problems or other health issues, should talk to a doctor before taking on the nirjala fast at all. Faith allows for limits, and many families let such members keep a modified fast with water or fruit.
