Why people convert Iran to AKST time
- Scheduling a call from Iran to AKST: a 10:00 AM start in Iran lands at 9:30 PM in AKST the previous day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -12h 30m gap: Iran and AKST 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 AKST is 8:30 PM in Iran.
- Keeping family and friends in sync: knowing that 8:00 PM in Iran is 7:30 AM in AKST makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM IRST" is unambiguous; "3 PM" across a -12h 30m gap is not.
- With a -12h 30m gap there is no shared 9-to-5 window, so alternate the early start: one week Iran takes the early slot, the next week AKST does.
