Daylight Saving Time Considerations

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

IST (IST/IDT) stands for the timezone used in Tel Aviv, Israel (UTC+2). IRST (IRST/IRDT) is the timezone used in Tehran, Iran (UTC+3:30). Tel Aviv is 1 hours and 30 minutes behind Tehran.

To convert IST to IRST, add 1.5 hours to IST time. For example, IST 9:00 AM = IRST 10:30 AM.
