Offices in Kolkata work Monday to Friday, typically 10:00–18:00 local time. Lunch is usually 13:30–14:30, and a meeting proposed inside it will be moved. The city's economy runs on IT services, financial back offices, education and port and logistics, which is who you are most likely to be calling. The day starts later than in Mumbai or Bangalore, and Durga Puja stops the city more completely than any national holiday.
The dates that most often break a cross-border schedule are Durga Puja (four to five days in September or October), Kali Puja and Diwali (October or November), Poila Boishakh (14 or 15 April) and Independence Day (15 August). Expect slow replies during Durga Puja week.
