PST to AEST Converter – Convert Pacific Time to Australian Eastern Time

AEST is 18 hours ahead of PST, so to convert mentally, add 18 hours to your PST time. For example: 9:00 AM PST = 3:00 AM AEST (next day). Our converter automatically adjusts for Daylight Saving Time so you always get the right result.

AEST (Australian Eastern Standard Time, UTC+10) is 18 hours ahead of PST (Pacific Standard Time, UTC-8) during standard time. For example, 9:00 AM PST = 3:00 AM AEST (next day). During DST periods, this difference changes by 1 hour when one or both zones observe Daylight Saving Time — our converter automatically applies the correct offset for any date you select.

AEST is 18 hours ahead of PST, so standard 9–5 business hours do not overlap. The most practical window is early morning in PST (7–9 AM), which falls in the evening in AEST — for example, 7:00 AM PST = 1:00 AM AEST (next day). Use our meeting planner to find the exact time for your date, especially around DST transitions.

Yes. PST (Pacific Standard Time) observes Daylight Saving Time. Clocks spring forward to PDT (UTC-7) on the second Sunday in March, and fall back to PST on the first Sunday in November. During the DST period, the difference with AEST changes by 1 hour. Our converter always uses the current offset for the date you select.

Major cities in the PST (Pacific Standard Time, UTC-8) timezone include: Los Angeles, San Francisco, Seattle, Portland, Las Vegas, Vancouver. These cities switch to PDT (UTC-7) from the second Sunday in March to the first Sunday in November.

Major cities in the AEST (Australian Eastern Standard Time, UTC+10) timezone include: Sydney, Melbourne, Canberra, Hobart (Brisbane uses AEST year-round without DST). These cities switch to AEDT (UTC+11) from the first Sunday in October to the first Sunday in April.

AEST is 18 hours ahead of PST. Because PST and AEST are 18 hours apart, there is no standard business-hour overlap — plan for one side to take an early morning or late evening call. Always include both local times in calendar invites (for example, "2:00 PM PST / 8:00 AM AEST (next day) AEST"). Double-check around March and November (or March/October for European zones) when DST transitions can shift the offset by 1 hour.
