Chhath Parva: The Sun Festival of Nepal

Chhath Parva is the great sun-worship festival of Nepal's southern plains — a four-day celebration of devotion, purity and gratitude to Surya, the Sun God. Among the most physically demanding festivals in South Asia, it draws families to riverbanks at dawn and dusk to make offerings to the rising and setting sun, and it is especially powerful in the historic city of Janakpur.

What Chhath celebrates

Chhath honours Surya and the goddess Chhathi Maiya, thanking the sun for sustaining all life and praying for the health, prosperity and longevity of family members. It is a festival of extraordinary discipline and purity, with no idols, priests or temple intermediaries — devotees worship the sun directly. It is observed mainly by communities of the Terai (Madhesh).

When it falls

Chhath takes place in the lunar month of Kartik, usually late October or November, a few days after Tihar, peaking on the sixth day after the new moon (hence "Chhath", meaning sixth). Dates shift each year — confirm with our best time to visit Nepal guide.

How and where it is celebrated

The festival unfolds over four days: ritual cleaning and a pure meal (Nahay Khay), a day-long fast broken at evening (Kharna), the offering of arghya to the setting sun, and finally arghya to the rising sun at dawn. Devotees — mostly women — observe a punishing nirjala (waterless) fast of around 36 hours and stand waist-deep in rivers and ponds to make their offerings. Chhath is strongest in the Terai, especially Janakpur, and is also widely celebrated along Kathmandu's Bagmati riverbanks.

What travellers will see

Expect riverbanks and ghats crowded with families at dawn and dusk; rows of devotees standing in water facing the sun; offerings of fruit, sugarcane and thekua sweets arranged in bamboo baskets; oil lamps and singing; and a deeply reverent, communal atmosphere. The early-morning sun offering is especially moving.

Chhath is notable for its emphasis on purity and self-reliance: the prasad is prepared at home with painstaking cleanliness, often by the fasting woman herself, and is cooked without onion, garlic or even tasting during preparation. Whole families take part in the preparations, with men and children helping carry the heavy bamboo baskets (daura and soop) of offerings to the riverside. The festival is strikingly egalitarian — there is no priestly hierarchy, and people of all castes worship side by side at the water's edge. Folk songs dedicated to Chhathi Maiya, sung in Maithili, Bhojpuri and other regional languages, drift across the ghats through the night before the sunrise offering.

For travellers, Chhath offers a window into the rich Maithili culture of the Terai, at its most concentrated in the temple city of Janakpur.

Tips for visitors

• Visit a riverbank or ghat at sunrise on the final day for the most powerful scenes — Janakpur or Kathmandu's Bagmati ghats.
• Keep a respectful distance from worshippers in the water; this is intensely devotional.
• Ask before photographing fasting devotees and their offerings.
• Dress modestly and arrive early, as crowds form before dawn — our Nepal culture and etiquette guide has more.

Chhath caps the great autumn festival season that runs from Teej through Dashain and Tihar, and shares its riverside devotion with the winter festival Maghe Sankranti. See where it sits in the full festival calendar of Nepal.
