Understanding the -7h Gap: AEDT vs GST
AEDT runs on Australian Eastern Daylight Time (AEDT) at UTC+11:00. GST runs on Gulf Standard Time (GST) at UTC+04:00. That puts AEDT 7 hours behind GST — a difference of -7h at the current offsets.
In practice, when it is 9:00 AM in AEDT it is 2:00 AM in GST. Midnight in AEDT is 5:00 PM in GST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert AEDT to GST time
- Scheduling a call from AEDT to GST: a 10:00 AM start in AEDT lands at 3:00 AM in GST, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both AEDT and GST are inside the 9-to-5 working day between 4:00 PM and 5:00 PM AEDT time (9:00 AM–10:00 AM GST). That is roughly 1 hours of usable overlap.
- Coordinating a AEDT-based team with GST 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 AEDT" is unambiguous; "3 PM" across a -7h gap is not.
- Block 4:00 PM–5:00 PM AEDT as the recurring meeting window if you work primarily from AEDT and need GST colleagues present.
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.
About GST (Gulf Standard Time)
Gulf Standard Time (GST) is the time zone used in the United Arab Emirates, Oman, and other Gulf states. GST does not observe daylight saving time. Dubai and Abu Dhabi, major international business and tourism hubs, operate on GST.
Best time to call between AEDT and GST
Both AEDT and GST sit inside the 9 AM – 5 PM working day between 4:00 PM–5:00 PM AEDT, which is 9:00 AM–10:00 AM GST. That gives roughly 1 hours of shared time — the safest window for a live call or meeting.
Business hours overlap
AEDT and GST overlap for only 60 minutes (4:00 PM–5:00 PM AEDT), so meetings have to be booked precisely.
AEDT is 7 hours behind GST (AEDT UTC+11:00 → GST UTC+04:00). The shared working window is 4:00 PM–5:00 PM AEDT. Remember to re-check around daylight-saving transitions.
