AEST vs PST Time Difference

How to Find the Time Difference Between AEST and PST

Australian Eastern Standard Time (AEST, UTC+10) is 18 hours ahead of PST (Pacific Standard Time, UTC-8). Looking for Pitcairn Standard Time? See /time-converter/pst-pitcairn-time-zone.

1. Open the comparison page: Visit https://www.xconvert.com/time-converter/aest-vs-pst to see Australian Eastern Standard Time and Pacific Standard Time lined up in the visual comparison grid. This view is useful when you are scheduling a call between Australia and the west coast of North America, such as coordinating with teams in Australia while clients or partners work in Canada, Mexico, or the United States.

2. Add relevant comparison cities: 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 Standard Time coverage. This is especially practical for remote product teams, media companies, customer support operations, and e-commerce businesses that need to overlap Australia-based work with North American Pacific schedules.

3. Drag to select a meeting window: Click Select to enter selection mode, then drag across the grid to highlight a time range in purple; you can adjust the left or right handles or drag the center to move the whole block. For example, drag from 9:00 AEST to 12:00 AEST to see that this corresponds to 15:00 PST to 18:00 PST on the previous day, which quickly shows why an Australian morning meeting lands in the prior afternoon for Pacific Standard Time participants.

4. 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 useful when sending a confirmed handoff window to a distributed team, adding a cross-border sales call to calendars automatically, or sharing a precise overlap period with contractors in Australia and Pacific North America.

AEST vs PST Offset Explained

Australian Eastern Standard Time is UTC+10, while Pacific Standard Time is UTC-8. That means PST is 18 hours behind AEST, or viewed the other way, AEST is 18 hours ahead of Pacific Standard Time. In practical scheduling 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.

This large gap affects how teams build overlap into the workday. AEST afternoon hours can still connect with Pacific Standard Time evening, as shown by 15:00 AEST = 21:00 PST on the previous day and 18:00 AEST = 0:00 PST. That makes AEST mornings and early afternoons the most common windows for Australia-to-Pacific calls, especially for software releases, agency reviews, logistics updates, and support escalations that need same-cycle communication.

Both abbreviations on this page refer to standard time, not daylight time. AEST is the standard-time abbreviation used in Australia, and its daylight saving counterpart is AEDT; Pacific Standard Time is the standard-time abbreviation used in Canada, Mexico, and the United States, and its daylight saving counterpart is PDT. Seasonal schedule changes matter because organizations often switch between these standard and daylight forms during the year, so teams planning recurring meetings should confirm whether they are working specifically in AEST and Pacific Standard Time or in their daylight-saving counterparts.

Working Across Australia and Pacific Standard Time Regions

Australian Eastern Standard Time is used in Australia, while Pacific Standard Time is used in parts of Canada, Mexico, and the United States. That makes this comparison common for international work involving Australian headquarters, North American regional offices, outsourced creative teams, cloud operations, gaming studios, and customer success teams serving users across the Pacific.

The 18-hour difference means same-day collaboration is limited, so many organizations rely on structured handoffs instead of long live meetings. For example, an Australia-based team can finish a work block at 18:00 AEST, which matches 0:00 PST, while earlier checkpoints such as 12:00 AEST = 18:00 PST on the previous day are better suited for live reviews, launch approvals, or issue triage before Pacific Standard Time teams log off.

Best Times to Schedule AEST to Pacific Standard Time Meetings

The most workable meeting windows usually start from the AEST morning through late afternoon, because those hours align with the previous day in Pacific Standard Time. A 9:00 AEST start maps to 15:00 PST on the previous day, which is useful for end-of-day syncs with west coast North American teams, while 15:00 AEST = 21:00 PST on the previous day can still work for urgent discussions but is less comfortable for routine meetings.

For recurring calls, many teams choose a narrow overlap and keep it consistent to reduce confusion. Sales teams speaking with Pacific accounts, engineering teams managing overnight deployments, and operations groups coordinating shipments or support queues often use the grid to compare several candidate windows visually, then export the chosen slot to Google Calendar or ICS so every participant receives the meeting in local time.

Frequently Asked Questions

What is the time difference between AEST and Pacific Standard Time?

Australian Eastern Standard Time is 18 hours ahead of Pacific Standard Time, and Pacific Standard Time is 18 hours behind AEST. AEST is UTC+10 and Pacific Standard Time is UTC-8, so the gap is large enough that many meetings fall on different calendar days for the two sides.

Is PST Pacific Standard Time or Pitcairn Standard Time?

On this page, PST means Pacific Standard Time (UTC-8). PST can also refer to Pitcairn Standard Time (UTC-8), and if you need that meaning, use /time-converter/pst-pitcairn-time-zone instead.

When it is 9:00 AEST, what time is it in Pacific Standard Time?

9:00 AEST = 15:00 PST on the previous day. This is a useful reference point for remote teams because an Australian morning meeting reaches Pacific Standard Time participants in the prior afternoon, which is often one of the easiest windows for live collaboration.

When it is noon in AEST, what time is it in Pacific Standard Time?

12:00 AEST = 18:00 PST on the previous day. That makes Australian lunchtime a practical option for speaking with Pacific Standard Time colleagues near the end of their workday, especially for status reviews, approvals, or client updates that need same-cycle feedback.

Is AEST always the same as Australian daylight saving time?

No. AEST is a standard-time abbreviation, while AEDT is its daylight saving counterpart. That distinction matters for recurring meetings because a calendar invite created for AEST is not the same as one created for AEDT, and the meeting relationship with Pacific Standard Time can shift seasonally when daylight-saving schedules apply.

Is Pacific Standard Time the same as PDT?

No. Pacific Standard Time is the standard-time abbreviation, while PDT is its daylight saving counterpart. If your team works with offices in Canada, Mexico, or the United States, this difference matters because a meeting labeled PST should be treated differently from one labeled PDT during parts of the year.

What are the most useful AEST to Pacific Standard Time conversion examples?

Several common reference points make planning easier: 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 show that Australian business hours usually map to the previous afternoon, evening, or midnight in Pacific Standard Time, which is why teams often prefer AEST morning or midday for live calls.
