Tehran & Novosibirsk — Business & Scheduling Guide
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. Novosibirsk (Russia) is one of the world's largest economies spanning 11 time zones, known for oil and gas, mining, defense, agriculture, and IT. With a 3.5-hour time difference, professionals frequently schedule cross-border calls between these two cities for international trade, remote team collaboration, and client meetings.
Scheduling Meetings Between Tehran and Novosibirsk
The 3.5-hour difference between Tehran and Novosibirsk requires careful scheduling. The best overlap window is typically 2–4 hours when both cities are within working hours. Iranian business hours are typically 8 AM–4 PM Saturday–Wednesday, with Thursday as a half-day and Friday off. Russian business hours are typically 9 AM–6 PM, with Moscow as the primary business hub and a growing tech sector. Teams often designate specific "overlap hours" for real-time collaboration and use asynchronous communication (Slack, email, recorded video) for the rest of the day.
Daylight Saving Time Considerations
Tehran observes Daylight Saving Time (IRST/IRDT), but Novosibirsk does not — it stays on NOVT year-round. This means the time difference between Tehran and Novosibirsk changes by 1 hour when Tehran switches clocks. During Iran's summer, the gap is 2.5–4.5 hours instead of the standard 3.5 hours. Mark DST transition dates on your calendar to avoid missed meetings.
Collaboration Tools & Workflow
The 3.5-hour gap between Tehran and Novosibirsk means teams get roughly half a day of overlapping work hours. Successful cross-timezone teams typically batch synchronous activities (standups, reviews, planning) into the overlap window and reserve solo deep work for non-overlapping hours. Tools like Loom for async video updates, Slack with status indicators showing each team's local time, and shared Notion docs help bridge the gap. Many teams adopt a "follow-the-sun" workflow where handoffs happen at the edges of each team's workday.
Remote Work Between Tehran & Novosibirsk
Tehran, a key city in Iran, and Novosibirsk, a key city in Russia, are well-connected for remote work. With a manageable 3.5-hour time difference, distributed teams can maintain a near-synchronous workflow. Both cities have strong internet infrastructure, coworking spaces, and established remote work cultures. For freelancers and remote workers, this time zone pairing is ideal — you can serve clients in Novosibirsk from Tehran (or vice versa) without disrupting your standard workday.
