Why people convert AEDT to Perth time
- Scheduling a call from AEDT to Perth: a 10:00 AM start in AEDT lands at 7:00 AM in Perth, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both AEDT and Perth are inside the 9-to-5 working day between 12:00 PM and 5:00 PM AEDT time (9:00 AM–2:00 PM AWST). That is roughly 5 hours of usable overlap.
- Coordinating a AEDT-based team with Perth 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 -3h gap is not.
- Block 12:00 PM–5:00 PM AEDT as the recurring meeting window if you work primarily from AEDT and need Perth 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 AWST (Australian Western Standard Time)
Australian Western Standard Time (AWST) is used in Western Australia. WA does not observe daylight saving time, having rejected it in multiple referendums. Perth is the most remote major city in the world.
