Tehran Time Zone Guide
Tehran operates in Iran Standard Time (IRST), positioned at UTC+3:30—one of only a few half-hour offset timezones globally. This unique 30-minute deviation places Iran precisely between standard hourly timezone boundaries, reflecting its longitude position in the Middle East. As of 2022, Iran no longer observes daylight saving time, maintaining IRST year-round after decades of seasonal clock changes that followed the Persian solar calendar. The elimination of DST simplifies international coordination for businesses and travelers dealing with Tehran, though it creates shifting time differences with countries that still observe seasonal changes. Tehran's timezone encompasses all of Iran, from the Caspian Sea coast to the Persian Gulf, providing uniform timekeeping across the nation's diverse geography. The half-hour offset means Tehran shares no exact timezone with major global financial centers, requiring careful calculation for international meetings and financial trading. Understanding Tehran's IRST designation is essential for scheduling video conferences, planning travel itineraries, and coordinating with Iranian business partners across sectors from energy to technology.
Business Hours in Tehran
Tehran's business culture operates on a Saturday-to-Wednesday workweek, distinctly different from Western Monday-to-Friday schedules. Standard office hours run from 8:30 AM to 5:00 PM IRST, though many private companies adopt flexible schedules. Thursday is a half-day in most sectors, with businesses closing around noon, while Friday serves as the official weekend day when most commercial activity ceases. Government ministries and public institutions typically operate 7:30 AM to 2:30 PM, front-loading productivity into morning hours. Tehran's banking sector maintains stricter schedules, opening at 8:00 AM and closing by 4:00 PM on working days, with limited Thursday operations. Retail presents a contrasting pattern—traditional bazaars like the Grand Bazaar operate morning through early evening, while modern shopping malls in districts like Elahieh and Zafaraniyeh stay open until 9:00 PM or 10:00 PM. The Tehran Stock Exchange operates morning-only sessions from 9:00 AM to 12:30 PM, concentrating trading into a compact 3.5-hour window. International businesses coordinating with Tehran must account for the Friday closure and Thursday half-day when scheduling deliverables, conference calls, or expecting responses to time-sensitive communications across global supply chains.
