Tehran to Tijuana Time

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. Tijuana (Mexico) is a major manufacturing and trade partner in North America, known for automotive, aerospace, electronics assembly, and agriculture. 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 Tijuana

With Tijuana 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. Iranian business hours are typically 8 AM–4 PM Saturday–Wednesday, with Thursday as a half-day and Friday off. Mexican business hours typically run 9 AM–6 PM, with a culture that values personal relationships in professional settings. Consider recording meetings for those who can't attend live, and use shared documents for async collaboration.

Daylight Saving Time Considerations

Both Tehran and Tijuana observe Daylight Saving Time. Tehran uses IRST/IRDT (switching between standard and daylight time), while Tijuana 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.

Collaboration Tools & Workflow

With a 11.5-hour time difference, Tehran and Tijuana teams operate in a near "follow-the-sun" model. When one team logs off, the other picks up — enabling near-24-hour productivity on shared projects. The key challenge is handoff quality: teams should document decisions in shared tools (Notion, Confluence, Linear), record video updates with Loom, and write thorough pull request descriptions. Weekly all-hands meetings require someone to take an early morning or late evening call, so the best practice is to rotate this burden fairly between Tehran and Tijuana.

Remote Work Between Tehran & Tijuana

Tehran, a key city in Iran, and Tijuana, a key city in Mexico, represent a common corridor for distributed teams navigating a 11.5-hour time difference. Remote workers and freelancers operating between these cities should plan their day around the overlap window — typically the late morning for one city and early morning or late afternoon for the other. Using a world clock widget, setting Slack status with local time, and blocking "no-meeting" deep work hours outside the overlap are essential practices for productive cross-timezone remote collaboration between Tehran and Tijuana.

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

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