Why people convert PST to AEDT time
- Scheduling a call from PST to AEDT: a 10:00 AM start in PST lands at 5:00 AM in AEDT the next day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +19h gap: PST 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 4:00 AM in PST.
- Coordinating a PST-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 PST" is unambiguous; "3 PM" across a +19h gap is not.
- With a +19h gap there is no shared 9-to-5 window, so alternate the early start: one week PST takes the early slot, the next week AEDT does.
About PST (Pacific Standard Time)
Pacific Standard Time (PST) covers the west coast of North America, including tech hubs like San Francisco and Seattle, and entertainment capital Los Angeles. The Pacific Time Zone is home to Silicon Valley and the world's largest technology companies. During summer, clocks advance to Pacific Daylight Time (PDT, UTC-07:00). PST is also observed in Baja California, Mexico.
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 PST and AEDT
With a +19h offset there is no overlap inside a normal 9 AM – 5 PM day. AEDT opens at 9:00 AM AEDT, which is 4:00 AM in PST, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
PST and AEDT have no shared working hours because of the +19h gap. Teams need to alternate early starts or rely on asynchronous handovers.
PST is 19 hours ahead of AEDT (PST UTC-08:00 → 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.
