What is the time difference between PST and AEST?

Australian Eastern Standard Time (AEST) is 17 hours ahead of Pacific Standard Time (PST). PST uses a UTC offset of UTC-7, while AEST uses UTC+10. For example, when it's 9:00 AM in PST, it's 2:00 AM in AEST. Note that this difference may shift by one hour during daylight saving time transitions if the two zones change on different dates.

To convert PST to AEST, add 17 hours to the PST time. For example, 9:00 AM PST is 2:00 AM AEST, and 5:00 PM PST is 10:00 AM AEST. Keep in mind that during daylight saving time transitions, the offset between these timezones may temporarily change by one hour.

How many hours ahead is AEST from PST?

AEST is 17 hours ahead of PST. This means when it's 9:00 AM in PST, it's 2:00 AM in AEST, and when it's midnight in PST, it's 5:00 PM in AEST. The exact difference can vary by one hour during daylight saving time transitions. The conversion table above provides a complete hour-by-hour mapping.

Is AEST ahead or behind PST?

AEST is ahead of PST by 17 hours. Clocks in AEST show a later time than PST, meaning the day starts earlier in AEST relative to PST. For example, when it's morning in PST, it's already afternoon or evening in AEST. This gap may change by one hour during DST transitions.

Does PST observe daylight saving time?

Yes, Pacific Standard Time observes daylight saving time. During DST, the abbreviation changes to PDT and clocks move forward by one hour, typically in spring. Clocks then fall back in autumn, returning to standard PST time. This means the UTC offset for PST shifts between two values depending on the season.

What is the best time to call from PST to AEST?

When does daylight saving time change in PST?

Daylight saving time transitions vary by year and region. Pacific Standard Time observes DST, which typically shifts clocks forward by one hour in spring ("spring forward") and back in fall ("fall back"). During these transition periods, the time difference between PST and AEST may temporarily change by one hour, which can cause confusion for scheduled meetings or calls. It's important to double-check your conversions around transition dates, especially if the two timezones switch on different dates. Check our DST change calendar for exact transition dates in the current year.

Do PST and AEST ever have the same time?

No, PST and AEST are always 17 hours apart and never display the same clock time simultaneously. Both timezones observe DST and typically transition around the same period, so the standard difference remains consistent throughout the year. The 17 hours offset is determined by their fixed positions relative to the Prime Meridian (UTC). You can always rely on this consistent difference when planning across these timezones.
