Why people convert Iran to WET time
- Scheduling a call from Iran to WET: a 10:00 AM start in Iran lands at 6:30 AM in WET, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Iran and WET are inside the 9-to-5 working day between 12:30 PM and 5:00 PM IRST time (9:00 AM–1:30 PM WET). That is roughly 4 hours 30 minutes of usable overlap.
- Booking travel or deliveries: tracking WET local time against Iran keeps pickup windows and arrival estimates honest across the -3h 30m offset.
- Always state the zone abbreviation, not just the hour. "3:00 PM IRST" is unambiguous; "3 PM" across a -3h 30m gap is not.
- Block 12:30 PM–5:00 PM IRST as the recurring meeting window if you work primarily from Iran and need WET colleagues present.
