Baku & Tehran — Business & Scheduling Guide
Baku (Azerbaijan) is a Caspian energy hub connecting Europe and Central Asia, with key industries in oil and gas, petrochemicals, agriculture, and tourism. 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.
Scheduling Meetings Between Baku and Tehran
With only a 0.5-hour gap, Baku and Tehran have generous overlapping work hours. Morning calls in the earlier time zone align well with mid-day in the other. Azerbaijani business hours are typically 9 AM–6 PM, with oil and gas driving the economy. Iranian business hours are typically 8 AM–4 PM Saturday–Wednesday, with Thursday as a half-day and Friday off. Most teams find that late morning to early afternoon offers the widest window for collaboration.
Daylight Saving Time Considerations
Tehran observes Daylight Saving Time (IRST/IRDT), while Baku stays on AZT year-round. When Tehran switches to daylight time, the effective time difference shifts by 1 hour. This typically happens in spring and fall, and the exact dates vary by country. If you have recurring cross-timezone meetings, recalculate the schedule after each DST transition.
