Kolkata’s festival calendar is dominated by Durga Puja, the five-day celebration that dwarfs everything else on the Bengali calendar. Beyond the Puja, the city hosts Asia’s largest book fair, a major international film festival and year-round cultural programming reflecting its self-image as India’s intellectual capital.
Durga Puja
Durga Puja is Kolkata’s defining event, a five-day Hindu festival typically falling in late September or October based on the lunar calendar. The 2026 dates are expected around October 8-12 (verify at durga-puja.org). Over 3,000 pandals (temporary structures housing elaborately crafted idols of the goddess Durga) are erected across the city, each funded by a neighbourhood committee competing for prizes. The pandals range from traditional clay-and-straw constructions to architectural showpieces designed by artists. Pandal-hopping is the main activity: locals and tourists queue for 2-3 hours at the most elaborate pandals (Sree Bhumi Sporting Club, Ekdalia Evergreen, Santosh Mitra Square) between 22:00 and 04:00. Most pandals stay open 24 hours during the Puja days. The immersion ceremony (Visarjan) on the final day processes to the Hooghly River ghats. Hotels book out 2-3 months ahead and rates triple. For a preview without the crowds, visit Kumartuli in the 4-6 weeks before Puja to watch the idols being made. The best time to visit Kolkata guide discusses Puja-season logistics.
International Kolkata Book Fair
Asia’s largest book fair by attendance, drawing 2 million visitors over 12 days in late January and early February. Held at the Central Park Mela Ground in Salt Lake (Bidhannagar), the fair hosts 600-plus publishers from India and abroad with a guest country focus each year. Entry is 10 INR. Open daily 13:00-20:00 (weekdays) and 11:00-20:00 (weekends). The crowds peak on weekends; visit on a Tuesday or Wednesday afternoon for breathing room. Food stalls serve Bengali specialties. Reach by Metro to Central Park station or taxi (300-400 INR from central Kolkata). January weather is ideal: 26°C (79°F) with 10mm of rain.
Kolkata International Film Festival (KIFF)
India’s second-oldest international film festival, held over 8 days in mid-November. Screens 200-plus films across 12 venues with retrospectives, Indian language cinema and a competition section. The main venue is Nandan (the West Bengal Film Centre) on AJC Bose Road, with satellite screenings across the city. Tickets cost 60-100 INR per screening; delegate registration (500 INR) gives access to all films. The November dating means pleasant weather with 29°C (84°F) highs and minimal rain. Programme announced on kiff.in by late October.
Christmas and New Year on Park Street
Park Street, Kolkata’s historic entertainment strip, transforms during the Christmas-New Year week (December 22 to January 1). The street is illuminated, Allen Park hosts a Christmas market, and the restaurants (Flurys, Peter Cat, Mocambo) run special menus. The Park Street Christmas Festival includes live music stages and a carnival atmosphere. Christmas Eve midnight mass at St. Paul’s Cathedral (1847) on the Maidan draws large congregations. Book dinner reservations at Park Street restaurants 2 weeks ahead for December 24-25 and December 31.
Holi and Diwali in Kolkata
Holi (March, date varies) is celebrated more gently in Kolkata than in north India, with powdered colours (gulal) rather than the water-soaked street battles seen in Delhi. The best place to experience it is at the organised Holi events at cultural centres like Nandan or the Saturday Club, or in the Ballygunge and Salt Lake residential areas. Diwali (October-November, date varies) is celebrated as Kali Puja in Bengal, with fireworks across the city, especially intense in the north Kolkata neighbourhoods of Baghbazar and Kumartuli.
