Tehran (Iran) is one of the Middle East's largest economies with a young population, known for oil and gas, petrochemicals, automotive, and agriculture. With a 0.5-hour time difference, professionals frequently schedule cross-border calls between these two cities for international trade, remote team collaboration, and client meetings.
