This AEST to PST converter turns any time in Australian Eastern Standard Time (AEST) into Pacific Standard Time (PST), using your device clock so daylight saving is applied automatically. PST is 19 hours behind AEST when both zones are on standard time, and 17 hours behind during the summer months when clocks have shifted. AEST is UTC+10 (AEDT: UTC+11); PST is UTC−8 (PDT: UTC−7).
AEST covers Sydney, Melbourne, Canberra; PST covers Los Angeles, San Francisco, Seattle. Because both zones change their clocks on different dates, the difference is not constant through the year. The tables below show both cases, and the converter at the top always uses the rule in force on the date you pick.

Frequently asked questions
What is the time difference between AEST and PST?
PST is 19 hours behind AEST on standard time. During daylight saving the gap changes to 17 hours. That comes from the UTC offsets: AEST is UTC+10 and PST is UTC−8. For example, 9 am AEST = 2 pm PST the previous day, and in summer 9 am AEST = 4 pm PST the previous day.
Is PST ahead of or behind AEST?
PST is 19 hours behind AEST, so when it is noon in AEST it is 5 pm in PST the previous day. Ahead means the clock there already shows a later time; a call at 5 pm AEST lands at 10 pm PST.
Does AEST or PST observe daylight saving time in 2026?
AEST switches to AEDT (UTC+11) on April 5 and back on October 4 in 2026. PST switches to PDT (UTC−7) on March 8 and back on November 1. Between those dates the difference in the table above shifts by an hour, which is the usual cause of missed calls in spring and autumn.
What is the best time for a meeting between AEST and PST?
Office hours (9 am to 5 pm) do not overlap at all with a 19 hours difference. The least painful options are early morning in PST or early evening in AEST; for example 8 am AEST = 1 pm PST the previous day and 6 pm AEST = 11 pm PST the previous day. Rotate the inconvenient slot between the two sides for recurring calls.
Which cities use AEST and PST?
AEST (Australian Eastern Standard Time) is used in Sydney, Melbourne, Canberra, Brisbane (no DST). PST (Pacific Standard Time) is used in Los Angeles, San Francisco, Seattle, Vancouver. Some cities inside a zone skip daylight saving, noted in parentheses, so their offset matches only part of the year.
