Calgary Business Pulse

Culture Entrepreneurial, professional, and influenced by the energy and tech sectors.
Lunch Break 12:00 PM - 1:00 PM.
Pro Tip Best times for calls are 9:00 AM to 11:30 AM. Calgary is a practical, results-oriented city with a strong entrepreneurial spirit. Mountain Time is great for North American syncs. A professional but friendly and "no-nonsense" approach is the most effective here.

Tehran Business Pulse

Culture Relationship-heavy and formal. Respect for hierarchy is paramount.
Lunch Break 1:00 PM - 2:00 PM.
Pro Tip The work week is Saturday to Wednesday. Thursday is often a half-day. Call between 9:00 AM and 12:00 PM. Iranian business culture is very formal and involves "Taarof" (a complex system of etiquette); be patient, polite, and avoid rushing into business without proper greetings.
