WET and IRST on the World Map
The map below highlights the WET (Western European Time) and IRST (Iran Standard Time) timezone regions across the globe.
WET – Western European Time
UTC+00:00Western European Time (WET) is the time zone for Portugal, Morocco, and the Canary Islands, same as UTC+00:00.
- •Portugal is the only mainland European country in the WET time zone.
- •The Canary Islands are on WET despite being part of Spain (which uses CET).
- •WET is identical to GMT and UTC+00:00.
IRST – Iran Standard Time
UTC+03:30Iran Standard Time (IRST) is the time zone for Iran, 3 hours and 30 minutes ahead of UTC.
- •IRST is one of only a few time zones with a 30-minute offset.
- •Iran observes daylight saving time, switching to IRDT (UTC+04:30).
- •Tehran has a metropolitan population of over 16 million.
Understanding the +3h 30m Gap: WET vs Iran
WET runs on Western European Time (WET) at UTC+00:00. Iran runs on Iran Standard Time (IRST) at UTC+03:30. That puts WET 3 hours 30 minutes ahead of Iran — a difference of +3h 30m at the current offsets.
In practice, when it is 9:00 AM in WET it is 12:30 PM in Iran. Midnight in WET is 3:30 AM in Iran. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert WET to Iran time
- Scheduling a call from WET to Iran: a 10:00 AM start in WET lands at 1:30 PM in Iran, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both WET and Iran are inside the 9-to-5 working day between 9:00 AM and 1:30 PM WET time (12:30 PM–5:00 PM IRST). That is roughly 4 hours 30 minutes of usable overlap.
- Watching a live event or market open: WET viewers need 12:30 PM in Iran to catch a 9:00 AM start there, and 8:30 PM if the event is anchored to WET.
- Always state the zone abbreviation, not just the hour. "3:00 PM WET" is unambiguous; "3 PM" across a +3h 30m gap is not.
- Block 9:00 AM–1:30 PM WET as the recurring meeting window if you work primarily from WET and need Iran colleagues present.
