Tehran to Vancouver Time

Tehran (Iran) is an important regional economy, with key industries in diverse sectors including services and trade. Vancouver (Canada) is a resource-rich economy with strong ties to the US market, known for natural resources, technology, finance, and manufacturing. With a 11.5-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 Vancouver

With Vancouver 11.5 hours behind Tehran, there is minimal overlap in standard business hours. Most teams alternate meeting times to share the burden of early-morning or late-evening calls fairly. Business hours typically follow a 9 AM–5 PM schedule. Canadian business hours are typically 9 AM–5 PM, with a culture similar to the US but with bilingual (English/French) considerations. Consider recording meetings for those who can't attend live, and use shared documents for async collaboration.

Daylight Saving Time Considerations

Both Tehran and Vancouver observe Daylight Saving Time. Tehran uses IRST/IRDT (switching between standard and daylight time), while Vancouver uses PST/PDT. If their DST transitions happen on different dates — which is common, as the US, EU, and other regions change clocks on different weekends — the effective time difference between the two cities can shift by 1 hour for several weeks. Always double-check the actual offset during March–April and October–November.

IRST (IRST/IRDT) stands for the timezone used in Tehran, Iran (UTC+3:30). PST (PST/PDT) is the timezone used in Vancouver, Canada (UTC-8). Tehran is 11 hours and 30 minutes ahead of Vancouver.

To convert IRST to PST, subtract 11.5 hours from IRST time. For example, IRST 9:00 AM = PST 9:30 PM (previous day).
