Why people convert Edmonton to Iran time

Scheduling a call from Edmonton to Iran: a 10:00 AM start in Edmonton lands at 7:30 PM in Iran, so you can confirm the slot without doing the arithmetic yourself.
Handling a +9h 30m gap: Edmonton and Iran have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in Iran is 6:30 PM in Edmonton.
Booking travel or deliveries: tracking Iran local time against Edmonton keeps pickup windows and arrival estimates honest across the +9h 30m offset.
