See the current AEST to PST time difference, compare hours side by side, and plan calls or meetings with daylight saving adjustments.
How to Convert AEST to PST
Open the AEST to PST converter: Go to https://www.xconvert.com/time-converter/aest-to-pst-converter. The page loads with AEST and PST already shown in the visual comparison grid, which is useful if you are scheduling a call between an Australia-based team in Brisbane or Sydney business hours and colleagues on the US West Coast in Los Angeles, San Francisco, Seattle, or Vancouver-area Pacific business hours.
Add relevant comparison cities: Click + Add City and add cities such as Los Angeles, San Francisco, and Sydney or Brisbane depending on whether you want to compare fixed AEST against a specific Australian city. This is especially practical for software teams, mining and energy suppliers, university collaborations, and APAC-US customer support operations that often coordinate between eastern Australia and Pacific Time offices.
Drag to select a meeting window: Use the Select button if needed, then drag across the colored hourly grid on the AEST row to highlight a time range in purple; you can resize it with the left and right handles or move the whole range by dragging the center. For example, if you drag 9:00 AM to 11:00 AM AEST, the PST row shows 3:00 PM to 5:00 PM PST on the previous day, which immediately tells you that an Australian morning meeting lands in the previous afternoon in California.
Export and share the result: After selecting a range, use the export options shown on the page: ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. This is useful when you need to send a confirmed handoff window to a distributed engineering team, create a calendar invite for a client call, or share a link so everyone sees the exact converted time in their own local context.
Understanding the AEST to PST Time Difference
AEST is UTC+10:00 and PST is UTC-8:00, so AEST is 18 hours ahead of PST. That means when it is 9:00 AM in AEST, it is 3:00 PM in PST on the previous day. The date shift is the most important practical detail for meeting planning, because many AEST morning hours fall on the prior calendar day in Pacific Standard Time.
The difference changes seasonally when Pacific Time switches between standard time and daylight time, and when eastern Australian cities such as Sydney or Melbourne switch between AEST and AEDT. PST itself applies roughly from early November to mid-March, while the US West Coast uses PDT (UTC-7) for the rest of the year; in those months, the difference between AEST and Pacific Daylight Time becomes 17 hours instead of 18. If you are comparing fixed AEST rather than a city observing daylight saving, the AEST side stays at UTC+10 all year, but the Pacific side still changes.
In the United States, daylight saving time in Pacific Time begins on the second Sunday in March and ends on the first Sunday in November. In Australia, AEST itself does not include daylight saving, but many eastern cities move to AEDT (UTC+11) from the first Sunday in October to the first Sunday in April; during that period, Sydney and Melbourne are no longer on AEST. This matters because users often search for “AEST to PST” while actually meaning “Sydney to Los Angeles,” and the answer can differ by an hour depending on the month.
For business use, this time gap affects industries with regular Australia-US coordination, including SaaS support, game development, film post-production, financial services, and university research teams. A Brisbane operations team working in true AEST can hand off tasks at the end of its day to a California team just starting the previous-day afternoon, which is why the converter’s date row and visual timeline are important for avoiding off-by-one-day mistakes.
Best Times for Calls and Meetings Between AEST and PST
Because AEST is 18 hours ahead of PST, the most realistic overlap usually happens between early morning in AEST and afternoon of the previous day in PST. A strong working window is 8:00 AM-10:00 AM AEST = 2:00 PM-4:00 PM PST (previous day), which works well for project updates, agency-client reviews, and support escalations between Australia and the US West Coast.
Another practical option is 9:00 AM-11:00 AM AEST = 3:00 PM-5:00 PM PST (previous day). This is often one of the best windows for remote teams because it lands after lunch in California and at the start of the business day in eastern Australia, making it suitable for engineering standups, sales pipeline reviews, and legal or procurement check-ins.
If the Pacific side can meet later in the day, 7:00 AM-9:00 AM AEST = 1:00 PM-3:00 PM PST (previous day) gives even more flexibility for Australian teams that need to speak before local office activity becomes busy. This is common for companies handling overnight support queues, cloud infrastructure incidents, or media workflows where assets are handed from Australia to US-based editors or developers.
Late AEST afternoon is usually poor for PST participants because 4:00 PM AEST = 10:00 PM PST on the previous day, and 6:00 PM AEST = 12:00 AM PST. That means an after-hours meeting in Brisbane or another AEST location pushes the Pacific side into late evening or midnight, which is rarely sustainable except for urgent launches, incident response, or live event coordination.
If Pacific Time is on daylight saving and effectively using PDT, the overlap improves slightly because the gap becomes 17 hours instead of 18. In that season, 9:00 AM AEST = 4:00 PM PDT (previous day), which can make late-afternoon West Coast meetings easier to schedule than during the PST months.
Frequently Asked Questions
What is the time difference between AEST and PST?
AEST is 18 hours ahead of PST when you are comparing standard time to standard time. In practical terms, if it is Monday morning in AEST, it is usually Sunday afternoon in PST, so you need to check both the hour and the date before confirming a meeting.
When is 9 AM AEST in PST?
9:00 AM AEST is 3:00 PM PST on the previous day. For example, if your team in eastern Australia wants a 9 AM Tuesday call, your California-based participants would join at 3 PM on Monday during the PST period.
Does the difference between AEST and PST change during DST?
Yes, the difference changes when the Pacific zone moves to daylight saving time. AEST remains UTC+10 year-round, but the US West Coast changes from PST (UTC-8) to PDT (UTC-7) from the second Sunday in March to the first Sunday in November, so the gap becomes 17 hours during that period instead of 18.
What is the best meeting time between AEST and PST?
The best meeting window is usually 8:00 AM-11:00 AM AEST, which corresponds to roughly 2:00 PM-5:00 PM PST on the previous day. This gives Australia a normal morning slot and lets Pacific participants join during regular afternoon office hours, which is especially useful for product teams, account managers, and support leads.
Why does AEST to PST often show the previous day?
Because AEST is so far ahead of PST, converting from Australian eastern standard time to US Pacific standard time usually crosses the date boundary backward. For example, 10:00 AM Wednesday AEST = 4:00 PM Tuesday PST, so the converter’s date picker and horizontal timeline help prevent accidental scheduling on the wrong calendar day.
Is AEST the same as Sydney time?
Not always. AEST is a fixed offset of UTC+10:00, but Sydney observes daylight saving time and changes to AEDT (UTC+11:00) from the first Sunday in October to the first Sunday in April, so Sydney is not on AEST for part of the year. If you are scheduling with someone specifically in Sydney, you should compare the city directly rather than assuming AEST year-round.
How can I use the converter to schedule an Australia-US West Coast call?
Open the AEST to PST page, then drag across the AEST row to mark a likely meeting block such as 8 AM-10 AM AEST and check where it lands on the PST row. Once you find a workable slot like 2 PM-4 PM PST on the previous day, export it as an ICS file, send it through Gmail, add it to Google Calendar, or copy/share the link so both sides receive the same converted schedule.
