Detailed Guide to Every Festival & Vrat – Bengali Calendar September 2026
1. Aja Ekadashi – September 6, 2026 (Sunday)
Type: Vrat — Bhadra Krishna Ekadashi
Aja Ekadashi falls on Sunday, September 6, 2026 — the eleventh day (Ekadashi) of the dark fortnight (Krishna Paksha) of Bhadro. Every Ekadashi in the Bengali calendar is a sacred fasting day dedicated to Lord Vishnu, and Aja Ekadashi is considered one of the most spiritually powerful Ekadashis of the year.
The name “Aja” means “unborn” — a name of Lord Vishnu himself — and observing this fast is believed to free devotees from the cycle of karma accumulated over many lifetimes. Vaishnava devotees in West Bengal observe a strict fast on this day, spend the day in prayer and scripture reading, and break the fast on the following Dwadashi morning with a light sattvic meal.
Observance in Bengal: On Aja Ekadashi, devotees visit Vishnu temples, offer Tulsi leaves (sacred to Vishnu), light ghee diyas, chant the Vishnu Sahasranama (thousand names of Vishnu), and perform puja. ISKCON temples across Kolkata and at Mayapur observe Ekadashi with full programme including Mangal Aarti, Bhagavad Gita classes, and evening Kirtan.
2. Pradosh Vrat (Krishna Paksha) – September 8, 2026 (Tuesday)
Type: Vrat — Bhadra Krishna Trayodashi
Pradosh Vrat on Tuesday, September 8, 2026 is the first of two Pradosh fasts in September 2026. Pradosh Vrat falls on the Trayodashi (13th day) of both the dark and bright fortnights every month and is one of the most widely observed fasts in Bengal dedicated to Lord Shiva and Goddess Parvati.
The word “Pradosh” refers to the evening twilight hour — the specific window (approximately 1.5 hours after sunset) during which Shiva worship on this day is considered supremely auspicious. According to tradition, Lord Shiva performs his divine dance (Tandava) during this twilight hour on Pradosh, and all devas gather to witness it. Devotees who worship Shiva during this Pradosh Kaal are believed to receive his direct blessings for health, prosperity, and liberation.
Since this Pradosh falls on a Tuesday (Mangalvar), it is called Bhaum Pradosh — considered especially beneficial for removing debts, legal troubles, and obstacles related to Mars (Mangal) in one’s horoscope.
3. Amavasya (Bhadra Amavasya) – September 9, 2026 (Wednesday)
Type: Sacred Day — New Moon
Bhadra Amavasya on Wednesday, September 9, 2026 is the new moon day of the Bengali month of Bhadro — one of the most significant days in the monthly Panjika cycle for ancestral offerings and Pitru worship.
In Bengali tradition, Amavasya is the day when the boundary between the living and the ancestors is considered thinnest. Pitru Tarpan — the ritual offering of water, sesame (til), and flowers to departed ancestors — is performed at rivers, ponds, or at home on this day. The Tarpan at the Ganges (Hooghly River) in Kolkata is a deeply moving sight on Amavasya mornings — priests and devotees standing knee-deep in the river, facing the rising sun, offering water and prayers to their forebears.
Bhadra Amavasya also marks the end of the dark fortnight and the beginning of the bright fortnight (Shukla Paksha) that culminates in Bhadra Purnima and the Anant Chaturdashi festival.
4. Parsva Ekadashi (Bhadra Shukla Ekadashi) – September 16, 2026 (Wednesday)
Type: Vrat — Bhadra Shukla Ekadashi
Parsva Ekadashi on Wednesday, September 16, 2026 is the second Ekadashi of the month — falling on the bright fortnight (Shukla Paksha) of Bhadro. This Ekadashi is known as Parsva Ekadashi or Parivartini Ekadashi because it marks the day when Lord Vishnu, who is believed to rest in cosmic sleep (Yoga Nidra) during the four-month Chaturmas period, turns to his other side (Parsva = side) — a symbolic midpoint of the sacred Chaturmas season.
Devotees observe fasting and night-long vigil (jagaran), chanting Vishnu Bhajans and reading from the Bhagavata Purana. Parsva Ekadashi is particularly significant for Vaishnavas who observe all Ekadashi fasts throughout the year, as it falls within the auspicious Chaturmas window when all spiritual practices carry heightened merit.
5. Vishwakarma Puja / Kanya Sankranti – September 17, 2026 (Thursday)
Type: Public Holiday — West Bengal Government
Vishwakarma Puja on Thursday, September 17, 2026 is one of the most distinctively and joyfully Bengali festivals of the entire year. This is the day when West Bengal’s entire industrial and artisan workforce pauses to honour Bhagwan Vishwakarma — the divine architect and celestial engineer of the Hindu universe, revered as the patron deity of all craftsmen, mechanics, engineers, factory workers, and creative builders.
Vishwakarma’s legendary creations include Lanka (Ravana’s golden city), the flying chariot Pushpaka Vimana, Lord Krishna’s underwater city of Dwarka, and the divine weapons of the gods. His worship is an act of gratitude — recognising that every tool, every machine, and every act of skilled work is ultimately a gift from the divine craftsman himself.
Kanya Sankranti occurs on the same day — the astronomical moment when the Sun transitions from Leo (Simha) into Virgo (Kanya). Every Sankranti carries a Punya Kaal — an auspicious time window ideal for holy bathing, charitable giving (Daan), and ancestral offerings (Pitru Tarpan). The combination of Kanya Sankranti’s solar significance with Vishwakarma Puja’s devotional energy makes September 17 doubly auspicious.
6. Pradosh Vrat (Shukla Paksha) – September 18, 2026 (Friday)
Type: Vrat — Bhadra Shukla Trayodashi
The second Pradosh Vrat of September falls on Friday, September 18, 2026 — the Trayodashi of the bright fortnight. This Shukra Pradosh (Friday Pradosh) is considered especially auspicious for the fulfilment of desires related to Goddess Lakshmi and overall domestic happiness. Devotees observe the Pradosh Kaal Shiva puja in the evening, offer milk, bilva leaves, white flowers, and bel fruit to the Shiva Linga, and pray for family wellbeing and prosperity.
7. Anant Chaturdashi – September 20, 2026 (Sunday)
Type: Festival — Bhadra Shukla Chaturdashi
Anant Chaturdashi on Sunday, September 20, 2026 is the fourteenth day of the bright fortnight of Bhadro — a day of deep devotional significance. The festival is dedicated to Ananta (the Infinite) Vishnu — Lord Vishnu in his cosmic form resting on the infinite serpent Shesha. Devotees observe a fast, perform Ananta puja, and tie a sacred 14-knotted thread (Anant Sutra) on their wrist as a symbol of divine protection and infinite blessings.
In West Bengal, Anant Chaturdashi is also the day when the Ganesh Chaturthi festival (begun ten days earlier) concludes with the ceremonial immersion (Visarjan) of Ganesha idols in rivers and water bodies — a colourful, emotional, and musically vibrant procession that fills Kolkata’s streets with devotion.
8. Bhadra Purnima / Madhu Purnima – September 22, 2026 (Tuesday)
Type: Auspicious Full Moon
Bhadra Purnima on Tuesday, September 22, 2026 is the full moon of the Bengali month of Bhadro — also known as Madhu Purnima (Honey Full Moon). This full moon is associated with a beautiful Buddhist legend from ancient India — when a monkey offered Lord Buddha a bowl of honey as a gift, and an elephant cleared the forest path before him. The story of Madhu Purnima celebrates acts of simple, sincere devotion and compassion.
For Bengali Hindus, Bhadra Purnima is observed through sacred bathing at the Ganges, Pitru Tarpan, charitable giving, and evening puja. Temples remain illuminated throughout the Purnima night, and devotees participate in Satyanarayan Puja — a popular Bengali ritual performed on full moon days for household prosperity and the fulfilment of wishes.
9. Milad-un-Nabi / Eid-e-Milad – September 26, 2026 (Saturday) (Tentative)
Type: Public Holiday — West Bengal Government (Subject to moon sighting)
Milad-un-Nabi (Eid-e-Milad) tentatively falls on Saturday, September 26, 2026 — marking the birth anniversary of Prophet Muhammad (Peace Be Upon Him) on the 12th of Rabi’ al-Awwal in the Islamic lunar calendar. West Bengal’s large Muslim community observes this occasion with Milad assemblies at mosques, Naat recitations, processions, and charitable food distribution across all districts.
The West Bengal Government lists this as an official Public Holiday, though the exact date is subject to moon sighting confirmation. Since September 26 is also the Fourth Saturday (a standard bank holiday under RBI guidelines), banks in West Bengal remain closed regardless.

Bhadro – The Gateway to Durga Puja Season
September 2026 is the month of Bhadro (ভাদ্র) — the emotional turning point of the Bengali year. The monsoon rains are still present but the air is shifting. Paddy fields are at their most brilliantly green. The evenings are growing subtly cooler. And across Bengal, something wonderful is quietly beginning — the first invisible stirrings of Durga Puja anticipation. Artists in Kumartuli are shaping clay Durga idols. Pandal committees are finalizing designs. Every Bengali heart is beginning to feel that indescribable sensation Bengalis call Pujar gondho — the scent of Puja in the air — weeks before the festival itself arrives.
September’s Panjika observances — its Ekadashis, Pradosh fasts, Amavasya, Purnima — form the devotional rhythm that carries Bengalis through Bhadro and into the extraordinary season ahead.
