Kolkata Heads Into Festival Season
September in Kolkata is rarely quiet, and this year the run-up to Durga Puja is especially layered — not just with religious observances but with exhibitions, cultural events, and community gatherings that sit alongside the panchang calendar.
The stretch begins with Pradosh Vrat on August 26 — the evening fast observed on the thirteenth lunar day, dedicated to Lord Shiva. That is the opening beat of a two-week period that builds quickly.
August 28: The Most Layered Day of the Month
On August 28, three distinct occasions fall on the same date. Raksha Bandhan 2026 — the festival of sibling bonds — is one. Purnima, the full moon, is another. That combination alone gives the day weight across households throughout the city.
The third element is the Pre Puja Offline Exhibition, taking place at Netaji Colony seva sangha on August 28. This is exactly the kind of pre-Durga Puja pop-up that has become a fixture of Kolkata's seasonal rhythm — local artisans, clothing sellers, and home goods vendors setting up while the puja shopping window is still relatively early. Early in the season means less crowd pressure and first access to what is on offer, before the market thins out in the final days before the festival.
Sotoborshe Uttam at Kala Mandir
Stepping back from the religious calendar, September 6 brings something culturally significant and distinct: Sotoborshe Uttam at Kala Mandir. This event marks the centenary of Uttam Kumar — the iconic Bengali actor whose influence on Tollywood and on Bengali cultural identity has been lasting across generations.
Kala Mandir is one of Kolkata's most established cultural venues, with decades of significant performances and events in its history. A centenary commemoration at this venue for a figure as beloved as Uttam Kumar is the kind of occasion that brings together audiences across age groups — those who grew up watching his films and those encountering them now. Sotoborshe Uttam is worth putting on the calendar if you are in Kolkata this September.
Insider Tip: Pre-puja exhibitions like the Pre Puja Offline Exhibition at Netaji Colony seva sangha and Aaparajiitaa Exhibition Cum Sale at Bika Banquet tend to draw a mix of buyers and independent sellers from across the city. Going on the first or second day generally means fresher stock and shorter queues — both exhibitions are worth visiting early in their run rather than in the final stretch.
The Religious Calendar Through Mid-September
After Raksha Bandhan 2026 and Purnima on August 28, the next significant observance is Sankashti Chaturthi on September 1 — the Ganesha fast observed monthly on the fourth day of the waning fortnight.
Krishna Janmashtami 2026 follows on September 4. Kolkata has a significant Vaishnava tradition, and numerous temples and community spaces across the city mark the occasion with midnight ceremonies, fasting, and devotional programmes. The city's North Kolkata areas in particular have strong devotional communities that gather for Janmashtami each year.
Ekadashi on September 7 is the fortnightly fast observed by Vaishnava households. Pradosh Vrat returns on September 9. Amavasya, the new moon — a day for ancestral rites and remembrance — falls on September 11.
Ganesh Chaturthi 2026 arrives on September 14 to close this stretch of the calendar. While the festival is observed most prominently in Maharashtra, Kolkata's own Ganesh Puja tradition means the date registers in panchang-observing households across the city as well.
Aaparajiitaa Exhibition Cum Sale at Bika Banquet
September 12 brings the second major exhibition of this period: Aaparajiitaa Exhibition Cum Sale at Bika Banquet. The name — Aaparajiitaa, the unconquered — carries a distinctly Bengali cultural resonance. These pre-puja sales events have become an important part of the city's seasonal economy, giving sellers a structured platform and buyers an alternative to the concentrated rush of the final days before Durga Puja.
Bika Banquet provides the kind of indoor venue space that allows a multi-seller format to function effectively — with enough room for product variety across categories, from clothing and accessories to home goods and crafts.
Between the Pre Puja Offline Exhibition at Netaji Colony seva sangha at the end of August and the Aaparajiitaa Exhibition Cum Sale at Bika Banquet in mid-September, there is a useful two-week window for pre-puja shopping before the city's pace accelerates sharply in the final run-up.
