How to Find the Time Difference Between AEST and PST
Open the AEST vs PST page: Go to https://www.xconvert.com/time-converter/aest-vs-pst to load a visual comparison grid with AEST and PST already shown as separate rows. This view is useful when you are scheduling a call between eastern Australia and the west coast of North America, such as a Sydney-based operations team coordinating with partners in California, British Columbia, or Baja California.
Add comparison cities with + Add City: Click + Add City and search for cities that matter to your workflow, such as Sydney for Australian business hours and Los Angeles or Vancouver for Pacific-side meetings in media, software, logistics, or customer support. This helps remote teams compare AEST against specific PST locations used by companies working across Australia, the United States, Canada, Mexico, and the Philippines.
Drag across the grid to select a meeting window: Click Select, then drag across the colored timeline on the AEST row to highlight a range in purple; you can resize it with the left and right handles or move the entire block by dragging the center. For example, if you drag around 9:00 AEST, the grid shows 15:00 PST on the previous day, and if you extend the selection to 12:00 AEST, that lines up with 18:00 PST on the previous day, which is useful for checking whether an Australia morning meeting fits a Pacific-side late afternoon slot.
Export the selected time range: Once a range is highlighted, use the export options for ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. This is especially practical for cross-border project handoffs, because you can send the same confirmed window to an engineering team in Australia and a client-facing team on Pacific time without manually rewriting the schedule for each location.
AEST vs PST Offset Explained
AEST is Australian Eastern Standard Time (UTC+10) and PST is Pacific Standard Time (UTC-8). The time difference on this page is -18 hours behind, which means PST is 18 hours behind AEST. In practical terms, when it is 9:00 AEST, it is 15:00 PST on the previous day; when it is 12:00 AEST, it is 18:00 PST on the previous day; when it is 15:00 AEST, it is 21:00 PST on the previous day; and when it is 18:00 AEST, it is 0:00 PST.
This large gap strongly affects business coordination. An Australian morning often overlaps with the previous afternoon or evening in Pacific time, which is why many teams choose AEST morning calls for collaboration between Australia-based staff and west-coast teams in the United States or Canada. For example, a product team in eastern Australia can use a morning AEST slot to catch a Pacific team before the end of its previous workday.
Both abbreviations on this page are standard-time abbreviations, not year-round labels. AEST’s daylight saving counterpart is AEDT, and PST’s daylight saving counterpart is PDT. That matters because the displayed relationship applies specifically to AEST vs PST; during daylight saving periods, the abbreviations change, so users comparing seasonal schedules should make sure they are looking at the correct standard or daylight version before sending calendar invites.
AEST is used in Australia, while PST is used in Canada, Mexico, the Philippines, and the United States. That makes this comparison relevant for industries with regular Pacific-Australia contact, including software outsourcing, cloud operations, gaming, film and media distribution, higher education partnerships, and international freight coordination through Pacific-facing ports and airports.
Frequently Asked Questions
What is the time difference between AEST and PST?
The difference between AEST and PST is -18 hours behind, meaning PST is 18 hours behind AEST. A practical example is that 9:00 AEST equals 15:00 PST on the previous day, so an Australian morning meeting usually lands in the prior afternoon for Pacific participants.
Is AEST ahead of PST or behind PST?
AEST is ahead of PST by the relationship shown on this page, with PST sitting 18 hours behind AEST. This means the calendar day often changes during conversion, which is why 12:00 AEST becomes 18:00 PST on the previous day rather than the same date.
Why does AEST to PST often show the previous day?
Because PST is 18 hours behind AEST, many conversions cross back into the prior calendar date. For example, 15:00 AEST equals 21:00 PST on the previous day, so if an Australian team proposes an afternoon session, Pacific participants may actually be joining the evening before.
What is 9 AM AEST in PST?
9:00 AEST = 15:00 PST on the previous day. This is a common comparison for remote work because a 9 AM start in eastern Australia lines up with mid-afternoon Pacific time, making it one of the more workable overlap windows for handoffs, approvals, and end-of-day updates.
What is noon AEST in PST?
12:00 AEST = 18:00 PST on the previous day. That means an Australian lunchtime discussion reaches Pacific participants in the early evening of the day before, which can work for urgent coordination but is less ideal for routine recurring meetings.
What is 6 PM AEST in PST?
18:00 AEST = 0:00 PST. This conversion is important for teams considering after-hours support or release monitoring, because an early evening slot in eastern Australia lands at midnight in Pacific time and is usually unsuitable for standard office-hour collaboration.
Does this page account for daylight saving time?
This comparison is specifically for AEST and PST, which are both standard-time abbreviations. AEST changes to AEDT in daylight saving periods, and PST changes to PDT, so users should confirm they are comparing the correct abbreviation before planning recurring meetings across seasons.
Which countries use AEST and PST?
AEST is used in Australia. PST is used in Canada, Mexico, the Philippines, and the United States, so this comparison is relevant for companies managing Pacific-region customer support, international vendor calls, and cross-border project schedules involving Australia and North America.
When is the best overlap for AEST and PST business calls?
The most practical overlap usually comes when one side meets in the Australian morning and the other side joins in the Pacific previous afternoon. The examples on this page show why: 9:00 AEST = 15:00 PST (previous day) and 12:00 AEST = 18:00 PST (previous day), which gives a realistic window for teams trying to connect without pushing both sides too far outside normal working hours.
