Kartik shukla shashthi (October-November); 4-day festival starting from Kartik shukla chaturthi · bihar, jharkhand, uttar-pradesh, nepal, diaspora
(1) Karna (Mahabharata), son of Surya, popularized Chhath; (2) Sita performed Chhath at Munger after returning from Lanka; (3) Draupadi performed Chhath. Worship of Surya as the visible Brahman.
Chhaṭh — the four-day festival on Kārtika śukla ṣaṣṭhī (October-November) — is the oldest known Sūrya-worshipping festival in continuous practice. It originates in the Bhojpuri-speaking belt of Bihar, eastern UP, and Jharkhand, with its earliest references in the Ṛg Veda's hymns to Sūrya. The Mahābhārata describes Karṇa, son of Sūrya, performing the very rituals that Chhaṭh-observers perform today — pre-dawn arghya in standing-water at sunrise.
Sītā is also said in the Vālmīki Rāmāyaṇa to have performed Chhaṭh upon arriving at Munger after returning from Lanka. Draupadī performed it during the Pāṇḍavas' forest exile. The festival therefore stretches across the entire Hindu narrative tradition. Yet for most of recorded history, Chhaṭh remained a regional Bihar-eastern UP practice — until 20th-21st century migration spread it to every Indian metro and the global Indian diaspora.
Chhaṭh is uniquely demanding among Hindu festivals. The four days involve: Day 1 (Nahay-khay) — single satvik meal with kaddu-bhāt; Day 2 (Lohaṇḍā / Kharnā) — full-day fast broken in evening with kheer-puri, beginning a 36-hour nirjala fast; Day 3 (Sandhyā Arghya) — at sunset, women wade into rivers in saris and offer arghya to the setting sun; Day 4 (Uṣā Arghya) — at sunrise, return for offering to the rising sun, breaking the 36-hour fast.
Chhaṭh is the festival of total surrender to the sun. Unlike most Hindu festivals where worship is conducted through deity-idols, Chhaṭh is direct: the sun himself is the deity, the river-water is the temple, the standing devotee is the offering. The 36-hour fast is among the most-difficult in the Hindu calendar; the offering to setting sun (the sun on his way to die) and to rising sun (the sun reborn) is a meditation on death and rebirth. Chhaṭh-vratīs are described as having achieved siddhi for their respective wishes — the festival has a singular reputation for granting whatever is asked. This is partly because the discipline is so total that nothing is left to ask for.
Day 1 — Nahay-khay (Kārtika śukla caturthī)
Bath in river or holy water. Single satvik meal — kaddu (pumpkin) bhāt with chana dal cooked without onion-garlic. Begin fast.
Day 2 — Lohaṇḍā / Kharnā (Kārtika śukla pañcamī)
Day-long fast. In evening, prepare kheer (rice-jaggery-milk pudding) and roti. Break fast with this meal eaten in silence. Then begin a continuous 36-hour nirjala fast.
Day 3 — Sandhyā Arghya (Kārtika śukla ṣaṣṭhī)
Continue fast. At sunset, go to riverbank with the thali of offerings. Wade into the river, holding the soop with offerings. As sun reaches the horizon, offer arghya — pour water from a small vessel as the sun touches the water-line. Stand in water until sunset is complete. Return home for the night-long jagaran.
Day 4 — Uṣā Arghya (Kārtika śukla saptamī)
Pre-dawn: return to riverbank. Wade into water again. As the first sunrays appear, offer arghya to the rising sun. Break the 36-hour fast with the prasāda right at the riverbank.

Children often participate in the river-bank arghya alongside their mothers. The pre-dawn waking, the family walking to the riverbank with thalis on heads, the singing of Chhaṭh-folksongs — these are formative experiences. Older children (10+) can fast partially. The thekuwa-making is a kitchen project the whole family does together — measuring wheat flour, kneading with jaggery-water, deep-frying golden cookies. Tell them the Karṇa story (the sun's son who performed Chhaṭh-arghya) — Karṇa's sun-devotion is one of the great hero-narratives.
Chhaṭh in the diaspora has crystallised around Bihari-Bhojpuri-UP NRI communities in Houston, NYC, Toronto, and London. Designated 'Chhaṭh ghats' have been built at swimming pools and lakes in NRI-dense cities. For families without community access, the home-terrace Chhaṭh works: a large tank or kunḍ filled with water, the offering at sunset and sunrise, the 36-hour fast. The astronomical event (sun setting and rising) is identical worldwide.
