Why people convert AEDT to PDT time
- Scheduling a call from AEDT to PDT: a 10:00 AM start in AEDT lands at 4:00 PM in PDT the previous day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -18h gap: AEDT and PDT 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 PDT is 3:00 PM in AEDT.
- Booking travel or deliveries: tracking PDT local time against AEDT keeps pickup windows and arrival estimates honest across the -18h offset.
- Always state the zone abbreviation, not just the hour. "3:00 PM AEDT" is unambiguous; "3 PM" across a -18h gap is not.
- With a -18h gap there is no shared 9-to-5 window, so alternate the early start: one week AEDT takes the early slot, the next week PDT does.
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 PDT (Pacific Daylight Time)
Pacific Daylight Time (PDT) is observed from March to November on the Pacific coast. During PDT, the west coast is 7 hours behind UTC and only 2 hours behind the east coast's EDT.
Best time to call between AEDT and PDT
With a -18h offset there is no overlap inside a normal 9 AM – 5 PM day. PDT opens at 9:00 AM PDT, which is 3:00 PM in AEDT, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
AEDT and PDT have no shared working hours because of the -18h gap. Teams need to alternate early starts or rely on asynchronous handovers.
AEDT is 18 hours behind PDT (AEDT UTC+11:00 → PDT UTC-07:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
