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