Why people convert PDT to AEDT time
- Scheduling a call from PDT to AEDT: a 10:00 AM start in PDT lands at 4:00 AM in AEDT the next day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +18h gap: PDT and AEDT 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 AEDT is 3:00 AM in PDT.
- Coordinating a PDT-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 PDT" 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 PDT takes the early slot, the next week AEDT does.
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.
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 PDT and AEDT
With a +18h offset there is no overlap inside a normal 9 AM – 5 PM day. AEDT opens at 9:00 AM AEDT, which is 3:00 AM in PDT, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
PDT and AEDT have no shared working hours because of the +18h gap. Teams need to alternate early starts or rely on asynchronous handovers.
PDT is 18 hours ahead of AEDT (PDT UTC-07:00 → AEDT UTC+11:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
