Open the converter page: Go to https://www.xconvert.com/time-converter/aest-to-pst-converter to compare AEST (Australian Eastern Standard Time, UTC+10) with PST (Pacific Standard Time, UTC-8). The page opens with a visual timeline that is useful when you are planning a call between Australia and the west coast of North America, such as coordinating with clients, support teams, or logistics partners in Canada, Mexico, or the United States.
Add comparison cities: Click + Add City and search for cities that matter to your schedule, such as Sydney or Brisbane for AEST and Los Angeles, Vancouver, or Tijuana for Pacific Standard Time. This is especially helpful for industries that regularly span these regions, including software teams handing work from Australia to California, media companies coordinating release times, and freight or travel teams managing Pacific routes.
Select a time range on the grid: Use the Select button if needed, then drag across the colored timeline to highlight a meeting window in purple, and adjust it with the left or right handles. For example, if you drag across 9:00 AEST to 12:00 AEST, the grid shows 15:00 PST to 18:00 PST on the previous day, which quickly confirms that an Australian morning meeting lands in the prior afternoon for Pacific Standard Time participants.
Export and share the result: After selecting a range, use the export options for ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. This is practical when an operations manager in Australia needs to send a confirmed cross-border meeting slot to a Pacific Standard Time sales team so everyone receives the event in their own local calendar without manual re-entry.
Understanding the AEST to PST Time Difference
AEST (Australian Eastern Standard Time, UTC+10) is 18 hours ahead of Pacific Standard Time (UTC-8), and Pacific Standard Time is 18 hours behind AEST. In practical terms, this means the Pacific Standard Time date is often the previous day when you convert a morning or afternoon time from eastern Australia.
The conversion examples make that day shift clear. 9:00 AEST = 15:00 PST (previous day), 12:00 AEST = 18:00 PST (previous day), 15:00 AEST = 21:00 PST (previous day), and 18:00 AEST = 0:00 PST. These examples are useful for customer support rosters, overnight handoffs, and scheduling meetings where one side starts work as the other side is finishing the prior day.
Both abbreviations on this page are standard-time abbreviations rather than daylight-saving abbreviations. AEST’s daylight-saving counterpart is AEDT, and Pacific Standard Time’s daylight-saving counterpart is PDT, so the gap changes during parts of the year when Australia’s eastern states or the Pacific coast observe daylight saving time. That matters for recurring meetings, because a slot that works during standard time may shift by an hour during the months when AEDT or PDT is in effect.
Best Times for Calls and Meetings Between AEST and PST
Because AEST is 18 hours ahead of Pacific Standard Time, the most practical overlap usually happens when the Australian side meets in the morning and the Pacific Standard Time side joins on the previous afternoon or evening. This pattern is common for remote product teams, game studios, cloud operations groups, and agencies that need a same-cycle discussion before one region signs off.
The clearest working examples are the ones already mapped on the converter. 9:00 AEST = 15:00 PST (previous day) and 12:00 AEST = 18:00 PST (previous day), so an Australian morning to midday block lines up with a Pacific Standard Time afternoon window that is still reasonable for many office-based teams. That makes this range useful for project status calls, account reviews, and final approvals that need both regions online at once.
Later AEST times become harder for standard business meetings in Pacific Standard Time. 15:00 AEST = 21:00 PST (previous day) pushes the Pacific side into late evening, and 18:00 AEST = 0:00 PST reaches midnight, which is usually better suited to urgent operational handoffs than routine meetings. If you are setting a recurring weekly call, the most sustainable option is usually to keep the AEST side earlier in the day so the Pacific Standard Time side stays in the prior afternoon.
Frequently Asked Questions
What is the time difference between AEST and PST?
AEST (Australian Eastern Standard Time, UTC+10) is 18 hours ahead of Pacific Standard Time (UTC-8). Put another way, Pacific Standard Time is 18 hours behind AEST, which is why many conversions land on the previous day for the Pacific side.
When is 9 AM AEST in PST?
9:00 AEST = 15:00 PST (previous day). This is a useful reference point for teams in Australia that want to reach colleagues in Pacific Standard Time during the prior afternoon rather than late evening or overnight.
Does the difference between AEST and Pacific Standard Time change during DST?
Yes. AEST is the standard-time abbreviation for eastern Australia, and its daylight-saving counterpart is AEDT; Pacific Standard Time is the standard-time abbreviation for the Pacific zone, and its daylight-saving counterpart is PDT. During the months when daylight saving is observed in those regions, the gap changes, so recurring meetings should be reviewed whenever schedules switch between AEST and AEDT or between Pacific Standard Time and PDT.
What are the best meeting times between AEST and PST?
The most practical meetings usually fall in the AEST morning, because that maps to the previous afternoon in Pacific Standard Time. The examples show why: 9:00 AEST = 15:00 PST (previous day) and 12:00 AEST = 18:00 PST (previous day), which are workable for many business calls, sprint reviews, and client updates across Australia and the west coast of North America.
Why does PST show the previous day when converting from AEST?
Pacific Standard Time is 18 hours behind AEST, so converting from eastern Australia often crosses the date line backward on the calendar. That is why 9:00 AEST becomes 15:00 PST on the previous day, and 15:00 AEST becomes 21:00 PST on the previous day rather than the same date.
Is PST Pacific Standard Time or Pitcairn Standard Time?
On this page, PST means Pacific Standard Time (UTC-8). PST can also mean Pitcairn Standard Time (UTC-8), and if you need that meaning instead, use /time-converter/pst-pitcairn-time-zone.
Which countries use AEST and Pacific Standard Time?
AEST is used in Australia. Pacific Standard Time is used in Canada, Mexico, and the United States, which is why this conversion is common for trade, travel coordination, software delivery, and customer support between Australia and North America’s Pacific-facing markets.
When is 12 PM AEST in PST?
12:00 AEST = 18:00 PST (previous day). This conversion is often convenient for end-of-day reviews on the Pacific side, especially when an Australian team wants feedback before its own afternoon continues.
