Understanding the +7h 30m Gap: Iran vs AEDT

Why people convert Iran to AEDT time
- Scheduling a call from Iran to AEDT: a 10:00 AM start in Iran lands at 5:30 PM in AEDT, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Iran and AEDT are inside the 9-to-5 working day between 9:00 AM and 9:30 AM IRST time (4:30 PM–5:00 PM AEDT). That is roughly 0 hours 30 minutes of usable overlap.
- Coordinating a Iran-based team with AEDT contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM IRST" is unambiguous; "3 PM" across a +7h 30m gap is not.
- Block 9:00 AM–9:30 AM IRST as the recurring meeting window if you work primarily from Iran and need AEDT colleagues present.
About IRST (Iran Standard Time)
Iran Standard Time (IRST) is one of the few time zones with a 30-minute offset. Iran observes daylight saving time (IRDT, UTC+04:30) from late March to late September. Tehran, the capital, is one of the largest cities in the Middle East.
About AEDT (Australian Eastern Daylight Time)
Australian Eastern Daylight Time (AEDT) is the daylight saving period in south-eastern Australia, one hour ahead of Australian Eastern Standard Time (AEST, UTC+10:00). Because Australia is in the southern hemisphere, AEDT runs through the summer — from the first Sunday in October to the first Sunday in April — which is almost exactly the reverse of the European and North American schedules. New South Wales, Victoria, Tasmania and the Australian Capital Territory observe it; Queensland and the Northern Territory do not, so Brisbane stays on AEST year round while Sydney moves to AEDT. During AEDT, Sydney is 11 hours ahead of UTC and 16 hours ahead of New York.
Best time to call between Iran and AEDT
Both Iran and AEDT sit inside the 9 AM – 5 PM working day between 9:00 AM–9:30 AM IRST, which is 4:30 PM–5:00 PM AEDT. That gives roughly 0 hours and 30 minutes of shared time — the safest window for a live call or meeting.
Business hours overlap
Iran and AEDT overlap for only 30 minutes (9:00 AM–9:30 AM IRST), so meetings have to be booked precisely.
Iran is 7 hours 30 minutes ahead of AEDT (IRST UTC+03:30 → AEDT UTC+11:00). The shared working window is 9:00 AM–9:30 AM IRST. Remember to re-check around daylight-saving transitions.
