Our free AEST to PST converter instantly translates Australian Eastern Time from Sydney into Pacific Standard Time on the USA West Coast. Whether you are scheduling a meeting between Sydney, Melbourne, or Brisbane and Los Angeles, San Francisco, or Seattle, this tool removes the mental math and shows you the exact local time on both sides.
AEST to PST Time Difference
Australia Standard Time (AEST) is significantly ahead of Pacific Time. The exact gap depends on daylight saving time in both regions, which occur at opposite times of year: (Time-zone offsets follow the IANA Time Zone Database, the authoritative source operating systems use for time-zone rules.)
- Standard time (AEST, UTC+10): Sydney is 18 hours ahead of PST (UTC−8). This applies roughly from April to early October, when Australia is in standard time and the USA is on Pacific Standard Time.
- Opposite DST seasons: Because Australia's summer (DST) runs October–April while the USA's runs March–November, the gap swings between 17 and 19 hours across the year. When one side observes DST and the other doesn't, the gap shrinks; when both do (or neither does), it widens to 18 hours.
- Practically speaking, Sydney is nearly a full day ahead — a time in Sydney is almost always the same date in Los Angeles but the previous calendar day. For example, 9:00 AM on Tuesday in Sydney is 3:00 PM on Monday in Los Angeles.
Best Times to Schedule Sydney ↔ US West Coast Meetings
Because of the huge gap, overlapping working hours are extremely narrow. These windows tend to work best (using standard time as a guide):
- 7:00–9:00 AM AEST (Sydney morning) = 1:00–3:00 PM PST (Los Angeles previous day)— Sydney's early start matches LA's afternoon.
- 4:00–6:00 PM AEST (Sydney late afternoon) = 9:00–11:00 PM PST (Los Angeles previous day)— Sydney's end of day overlaps LA's evening, with day rollover.
Common Conversions
- 9:00 AM AEST = 3:00 PM PST (previous day)
- 12:00 PM (noon) AEST = 6:00 PM PST (previous day)
- 5:00 PM AEST = 11:00 PM PST (previous day)
- 8:00 PM AEST = 2:00 AM PST (same day)
Frequently Asked Questions
How many hours ahead is Sydney (AEST) from Los Angeles (PST)?
Sydney is 18 hours ahead of Los Angeles during standard time (AEST UTC+10 vs PST UTC−8). However, because daylight saving time occurs in opposite months between Australia and the USA, the gap swings between 17 and 19 hours depending on the time of year. The converter above accounts for the current period automatically.
Does daylight saving time change the AEST to PST difference?
Yes. Australia observes daylight saving time from October to April (Southern hemisphere summer), while the USA observes it from March to November (Northern hemisphere summer). Because these seasons are opposite, the time difference varies throughout the year—sometimes 17, sometimes 18, sometimes 19 hours. Check your specific dates with the converter.
What time is 9 AM AEST in Los Angeles?
9:00 AM AEST is 3:00 PM PST on the previous day during standard time. Remember the day rollover: when Sydney morning arrives, it's still the previous afternoon in Los Angeles.
