This PST to AEST converter turns any time in Pacific Standard Time (PST) into Australian Eastern Standard Time (AEST), using your device clock so daylight saving is applied automatically. AEST is 19 hours ahead of PST when both zones are on standard time, and 17 hours ahead during the summer months when clocks have shifted. PST is UTC−8 (PDT: UTC−7); AEST is UTC+10 (AEDT: UTC+11).
PST covers Los Angeles, San Francisco, Seattle; AEST covers Sydney, Melbourne, Canberra. 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 PST and AEST?
AEST is 19 hours ahead of PST on standard time. During daylight saving the gap changes to 17 hours. That comes from the UTC offsets: PST is UTC−8 and AEST is UTC+10. For example, 9 am PST = 4 am AEST the next day, and in summer 9 am PST = 2 am AEST the next day.
Is AEST ahead of or behind PST?
AEST is 19 hours ahead of PST, so when it is noon in PST it is 7 am in AEST the next day. Ahead means the clock there already shows a later time; a call at 5 pm PST lands at 12 pm AEST.
Does PST or AEST observe daylight saving time in 2026?
PST switches to PDT (UTC−7) on March 8 and back on November 1 in 2026. AEST switches to AEDT (UTC+11) on April 5 and back on October 4. 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 PST and AEST?
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 PST = 3 am AEST the next day and 6 pm PST = 1 pm AEST the next day. Rotate the inconvenient slot between the two sides for recurring calls.
Which cities use PST and AEST?
PST (Pacific Standard Time) is used in Los Angeles, San Francisco, Seattle, Vancouver. AEST (Australian Eastern Standard Time) is used in Sydney, Melbourne, Canberra, Brisbane (no DST). Some cities inside a zone skip daylight saving, noted in parentheses, so their offset matches only part of the year.
