Convert a specific time from PST to AEST
Pick any time and date to convert it both ways. The conversion runs in your browser against the real zone rules, so a date inside a daylight saving period gets that period's offset rather than today's.
What is the time difference between PST and AEST?
Australian Eastern Time is 17 hours ahead of Pacific Time. To go from PST to AEST you add 17 hours. That gap is not fixed. Across 2026 the distance between these two zones takes 3 different values, from 17 hours to 19 hours, because the two sides change their clocks on different dates. This page recomputes it rather than assuming.

What are the best hours to schedule a call between PST and AEST?
No hour of the standard 9:00 am to 5:00 pm working day falls inside working hours on both sides. Pacific and Australian Eastern are 17 hours apart, which is too far for an overlap, so somebody has to take a call outside their own working day. The least painful options are below, ranked by how close both sides sit to the middle of the afternoon.
| PST | AEST | Working hours | Note |
|---|---|---|---|
| 2:00 pm | 7:00 am the next day | PST only | afternoon in Pacific, early morning in Australian Eastern |
| 3:00 pm | 8:00 am the next day | PST only | afternoon in Pacific, mid morning in Australian Eastern |
| 4:00 pm | 9:00 am the next day | both sides | afternoon in Pacific, mid morning in Australian Eastern |
Does daylight saving change PST to AEST?
Pacific Time is currently on PDT and changes next on Sunday, November 1, 2026, when the clock falls back from 1:59 am to 1:00 am and the offset moves from UTC-7 to UTC-8.
Australian Eastern Time is currently on AEST and changes next on Sunday, October 4, 2026, when the clock jumps forward from 1:59 am to 3:00 am and the offset moves from UTC+10 to UTC+11.
Because the two sides do not move together, the answer to this conversion changes during the year. The United States changes on the second Sunday in March and the first Sunday in November, while the United Kingdom and European Union change on the last Sunday in March and the last Sunday in October. Those dates are weeks apart, which opens a window each spring and autumn where the usual gap is an hour out. The table above is built for today, not for an average day.
Is PST ahead of or behind AEST?
PST is behind AEST by 17 hours: when it is 12:00 pm in Pacific, it is 5:00 am the next day in Australian Eastern. One wrinkle worth knowing: PST and PDT are two names for the same zone, not two zones. Pacific Time reads PST in winter and PDT in summer. When somebody types "pst to aest" they nearly always mean the zone rather than the literal winter offset, so this page resolves PST to America/Los_Angeles and AEST to Australia/Sydney and applies whichever offset is genuinely in force on the day.
Pacific Time covers Los Angeles, San Francisco, Seattle and Vancouver. Australian Eastern Time covers Sydney, Melbourne and Canberra, where summer falls in December. The identifiers behind them are America/Los_Angeles and Australia/Sydney, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
