Open the PST to AEST converter: Go to https://www.xconvert.com/time-converter/pst-to-aest-converter, where Pacific Standard Time and Australian Eastern Standard Time are already set up for side-by-side comparison on the visual timeline grid. This is useful when you are planning a client call between the west coast of the United States or Canada and teams in eastern Australia, where the meeting often lands on the next calendar day in Australia.
Add comparison cities with + Add City: Click + Add City and add cities that commonly work with Pacific Standard Time and Australian Eastern Standard Time, such as Los Angeles, Vancouver, Sydney, or Brisbane. This helps remote teams in software, media, logistics, and customer support compare Pacific Standard Time business hours across North America with Australian Eastern Standard Time schedules in Australia on the same screen.
Drag to select a meeting window on the grid: Click Select, then drag across the Pacific Standard Time row to highlight a time range in purple, such as 9:00 to 12:00 PST, and use the left or right handles to refine the selection. That example lines up with 3:00 to 6:00 AEST the next day, which is a practical way to confirm whether a late-afternoon Australia meeting or a morning Pacific Standard Time handoff works for product reviews, agency approvals, or support escalations.
Export and share the selected time range: After selecting a range, use the export options for ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. These options are useful when you need to send a confirmed Pacific Standard Time to Australian Eastern Standard Time slot to a distributed team so everyone receives the meeting in their own calendar context without manually rewriting the time.
Understanding the PST to AEST Time Difference
Pacific Standard Time is UTC-8, while Australian Eastern Standard Time is UTC+10. Australian Eastern Standard Time is 18 hours ahead of Pacific Standard Time, which means a morning time in Pacific Standard Time appears in Australian Eastern Standard Time on the next day.
The conversion examples make that shift clear. 9:00 PST = 3:00 AEST (next day), 12:00 PST = 6:00 AEST (next day), 15:00 PST = 9:00 AEST (next day), and 18:00 PST = 12:00 AEST (next day). For business scheduling, this means Pacific Standard Time afternoon hours often become the next day's morning or midday in Australian Eastern Standard Time.
Both abbreviations on this page are standard-time abbreviations rather than daylight-saving abbreviations. Pacific Standard Time uses PDT as its daylight saving counterpart, and Australian Eastern Standard Time uses AEDT as its daylight saving counterpart, so the difference changes during parts of the year when one or both regions are observing daylight saving time rather than standard time. That matters for recurring meetings, because a time that works in the standard-time period may shift by a different number of hours in DST months.
Pacific Standard Time is used in Canada, Mexico, and the United States, while Australian Eastern Standard Time is used in Australia. That country coverage is relevant for cross-border work such as North American customer support, Pacific-facing logistics, gaming operations, and software engineering teams coordinating with Australian offices or contractors.
Best Times for Calls and Meetings Between PST and AEST
Pacific Standard Time and Australian Eastern Standard Time work best together when you intentionally use Pacific Standard Time morning hours, because Australian Eastern Standard Time is already 18 hours ahead. A 9:00 PST meeting lands at 3:00 AEST the next day, and 12:00 PST lands at 6:00 AEST the next day, which can suit late-afternoon follow-ups in Australia.
For teams that need a stronger overlap with Australian Eastern Standard Time work hours, 15:00 PST = 9:00 AEST (next day) is one of the clearest examples on this page. That pairing is useful for engineering standups, publishing handoffs, or account management calls where Pacific Standard Time staff can meet late in their day and Australian Eastern Standard Time staff can join at the start of theirs.
Another workable option is 18:00 PST = 12:00 AEST (next day), especially for urgent operational discussions or launch-day coordination. This gives Australian Eastern Standard Time teams a midday slot while Pacific Standard Time participants join in the early evening, which is often more realistic than trying to connect during Pacific Standard Time early mornings and Australian Eastern Standard Time overnight hours.
In practice, the most usable windows depend on which side can flex. If the Pacific Standard Time side can meet later in the day, Australian Eastern Standard Time participants get next-day morning or midday availability; if Pacific Standard Time participants only meet in the morning, Australian Eastern Standard Time often sees the meeting in the middle or later part of the next day.
Frequently Asked Questions
What is the time difference between PST and AEST?
Pacific Standard Time is 18 hours behind Australian Eastern Standard Time. Put another way, Australian Eastern Standard Time is 18 hours ahead of Pacific Standard Time, so a time selected in Pacific Standard Time usually appears on the following calendar day in Australia.
This large gap is why date awareness matters as much as clock time. If you schedule a Friday afternoon meeting in Pacific Standard Time, the Australian Eastern Standard Time side will usually see it on Saturday morning or midday.
When is 9 AM PST in AEST?
9:00 PST = 3:00 AEST (next day). This is a common conversion for teams in California, British Columbia, or other Pacific Standard Time areas that need to reach colleagues or clients in eastern Australia.
Because the Australian Eastern Standard Time result falls on the next day, it is important to confirm both the hour and the date before sending invitations. That next-day shift affects project deadlines, handoffs, and support coverage.
Does the difference between PST and AEST change during DST?
Yes, the difference changes when daylight saving time is in effect, because Pacific Standard Time changes to PDT and Australian Eastern Standard Time changes to AEDT during their respective daylight saving periods. The 18-hour difference on this page applies specifically to Pacific Standard Time and Australian Eastern Standard Time as standard-time abbreviations.
This matters most for recurring meetings that run across seasonal clock changes. A meeting series created during the standard-time period may no longer land at the same local hour once one side switches to its daylight saving counterpart.
What is the best meeting time between PST and AEST?
One of the most practical examples is 15:00 PST = 9:00 AEST (next day), because it places the meeting at the start of the Australian Eastern Standard Time workday. This is often a strong option for product teams, operations staff, and agencies that need live discussion without forcing the Australia side into an evening slot.
Another useful example is 18:00 PST = 12:00 AEST (next day), which creates a midday meeting in Australia. If the Pacific Standard Time side prefers morning meetings, 9:00 PST = 3:00 AEST (next day) and 12:00 PST = 6:00 AEST (next day) can still work, but they are less ideal for a full overlap with standard office hours in Australia.
Which countries use PST and AEST?
Pacific Standard Time is used in Canada, Mexico, and the United States. Australian Eastern Standard Time is used in Australia.
This country coverage is especially relevant for companies managing transpacific work. A North American team using Pacific Standard Time may be coordinating with Australian teams in customer success, digital services, ecommerce, or regional operations using Australian Eastern Standard Time.
Is PST Pacific Standard Time or Pitcairn Standard Time?
On this page, PST means Pacific Standard Time, which is UTC-8. PST can also refer to Pitcairn Standard Time, also UTC-8, and that meaning is covered separately at /time-converter/pst-pitcairn-time-zone.
The distinction matters because abbreviations can be ambiguous even when the UTC offset matches. If you are scheduling business meetings involving the west coast of North America and Australia, Pacific Standard Time is the intended meaning here.
