Tehran (Iran) is one of the Middle East's largest economies with a young population, with key industries in oil and gas, petrochemicals, automotive, and agriculture. Tashkent (Uzbekistan) is Central Asia's most populous country undergoing rapid economic reform, known for agriculture, textiles, natural gas, and gold mining. With a 1.5-hour time difference, professionals frequently schedule cross-border calls between these two cities for international trade, remote team collaboration, and client meetings.

Mark DST transition dates on your calendar to avoid missed meetings.
