Open the converter page: Go to https://www.xconvert.com/time-converter/pst-to-aest-converter. You’ll see Pacific Standard Time and Australian Eastern Standard Time already loaded in the comparison grid, which is useful when you’re planning a call from the U.S. or Canada to colleagues, customers, or suppliers in Australia.
Add comparison cities: Click + Add City and search for cities that matter to your schedule, such as Los Angeles or Vancouver on the Pacific side and Sydney or Brisbane on the Australian side. This makes the grid more practical for remote engineering handoffs, customer support coverage, and sales meetings that involve both Pacific Standard Time markets and Australian Eastern Standard Time business hours.
Select a meeting window on the grid: Click Select, then drag across the Pacific Standard Time row to highlight a time range in purple; you can resize it with the side handles or move it by dragging the center. For example, selecting 9:00 PST to 12:00 PST shows 3:00 AEST to 6:00 AEST the next day, which helps confirm that a late-morning Pacific Standard Time meeting lands in the early morning of the following day in Australian Eastern Standard Time.
Export and share the result: Once the time range is selected, use the export options for ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. That’s especially useful when a U.S.-Australia meeting needs to be sent to a distributed team so everyone sees the correct local time automatically in their own calendar.
Understanding the PST to AEST Time Difference
Pacific Standard Time is 18 hours behind Australian Eastern Standard Time, and Australian Eastern Standard Time is 18 hours ahead of Pacific Standard Time. In practical terms, this means the Australian side is already on the next calendar day for many standard business-hour conversions, which is why 9:00 PST = 3:00 AEST (next day) and 12:00 PST = 6:00 AEST (next day).
The same next-day pattern continues later in the Pacific Standard Time workday. For example, 15:00 PST = 9:00 AEST (next day) and 18:00 PST = 12:00 AEST (next day), so an afternoon meeting in Pacific Standard Time often becomes a morning or midday meeting in Australia the following day.
Both abbreviations on this page are standard-time abbreviations rather than daylight-saving ones. Pacific Standard Time uses PDT as its DST counterpart, and Australian Eastern Standard Time uses AEDT as its DST counterpart, so the difference changes during parts of the year when daylight saving is in effect; that is why it is important to distinguish PST from PDT and AEST from AEDT when scheduling across seasons.
Pacific Standard Time is used in parts of Canada, Mexico, and the United States, while Australian Eastern Standard Time is used in Australia. That geographic spread matters for industries such as software, media, logistics, tourism, and e-commerce, where teams often coordinate overnight support, next-day delivery planning, or regional launch timing between North America’s Pacific markets and Australia’s east-coast business day.
Best Times for Calls and Meetings Between PST and AEST
Because Australian Eastern Standard Time is 18 hours ahead of Pacific Standard Time, the most workable meetings usually happen when one side accepts either an early-morning start or a late-afternoon session. The conversion examples show the pattern clearly: 15:00 PST = 9:00 AEST (next day) and 18:00 PST = 12:00 AEST (next day), so a Pacific Standard Time afternoon lines up with the next morning to midday in Australian Eastern Standard Time.
For business calls, 15:00 PST to 18:00 PST is often the most practical range on this page because it maps to 9:00 AEST to 12:00 AEST the next day. That window is useful for product teams handing work from California or British Columbia to Australia, for agency-client reviews, and for account managers who need to speak during normal Australian office hours without asking the Australian side to join late at night.
Earlier Pacific Standard Time slots are usually less convenient for standard office schedules in Australia. The examples 9:00 PST = 3:00 AEST (next day) and 12:00 PST = 6:00 AEST (next day) show that a Pacific morning meeting becomes a very early next-day start in Australian Eastern Standard Time, which may work for urgent operations, incident response, or travel coordination but is usually less suitable for recurring team meetings.
If you manage remote teams, the grid is particularly helpful for spotting a repeatable overlap. You can drag across a Pacific Standard Time afternoon block and immediately see whether it lands in the Australian Eastern Standard Time morning, then save that range to Google Calendar or export an ICS file for weekly standups, support escalations, or partner check-ins.
Frequently Asked Questions
What is the time difference between PST and AEST?
Pacific Standard Time is 18 hours behind Australian Eastern Standard Time, and Australian Eastern Standard Time is 18 hours ahead of Pacific Standard Time. That large gap means many conversions cross into the next calendar day, which is why standard scheduling between North America’s Pacific region and Australia usually needs explicit date confirmation as well as time confirmation.
When is 9 AM PST in AEST?
9:00 PST = 3:00 AEST (next day). This means a morning meeting in Pacific Standard Time appears in Australian Eastern Standard Time during the early morning of the following day, which is important for booking calls with Australian teams and avoiding accidental same-day assumptions.
Does the difference between PST and AEST change during DST?
Yes, the difference changes when daylight saving time is involved because PST and AEST are both standard-time abbreviations. Pacific Standard Time changes to PDT during its daylight-saving period, and Australian Eastern Standard Time changes to AEDT during its daylight-saving period, so you should make sure you are comparing the correct abbreviations for the season rather than assuming the standard-time gap applies year-round.
What is the best meeting time between PST and AEST?
A practical meeting window is often based on the examples 15:00 PST = 9:00 AEST (next day) and 18:00 PST = 12:00 AEST (next day). That makes late afternoon in Pacific Standard Time one of the best options for regular business meetings because it lands in the next day’s morning to midday in Australian Eastern Standard Time, which is usually easier than asking Australian participants to join before dawn.
When is 12 PM PST in AEST?
12:00 PST = 6:00 AEST (next day). This can work for urgent coordination, airport transfers, overnight operations, or time-sensitive project updates, but for recurring meetings it is often too early for a normal Australian business schedule.
When is 3 PM PST in AEST?
15:00 PST = 9:00 AEST (next day). This is one of the most useful conversions for cross-border work because it places the meeting at the start of the Australian Eastern Standard Time business day, making it suitable for handoffs, daily planning, and client communication.
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); if you need that meaning instead, use /time-converter/pst-pitcairn-time-zone.
Why does PST to AEST usually show the next day?
Australian Eastern Standard Time is 18 hours ahead of Pacific Standard Time, so the Australian clock is far enough forward that many Pacific Standard Time hours fall on the following calendar day in Australia. The examples on this page show that clearly: 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).
