Synchronization Context

A 2 hours 30 minutes gap allows for a manageable shared window, typically in the morning or late afternoon. It requires some scheduling but supports daily synchronization.

Istanbul Business Pulse

Culture A bridge between East and West. Business is personal, and hospitality (tea/coffee) is a prerequisite.
Lunch Break 12:30 PM - 1:30 PM.
Pro Tip Aim for calls between 10:00 AM and 12:00 PM or 2:00 PM and 4:30 PM. Turkish business culture is highly relational; starting with "Nasılsınız?" (How are you?) and building rapport is essential. Avoid scheduling critical calls late on Friday afternoons.

Kolkata Business Pulse

Culture Intellectual and heritage-focused. Business often involves longer discussions and consensus.
Lunch Break 1:30 PM - 2:30 PM.
Pro Tip Best reached between 11:30 AM and 4:00 PM. Avoid the 1:30 PM - 2:30 PM lunch window. Business culture is intellectual and values detailed discussion; avoid overly aggressive "hard-sell" tactics. Note that the city slows down significantly during major festivals like Durga Puja.
