Los Angeles to Sydney Time Converter
Sydney is 17, 18 or 19 hours ahead of Los Angeles, and it's always the next calendar day for a Los Angeles morning. 9:00 AM in Los Angeles is 4:00 AM the next day in Sydney in northern winter (19 hours), 3:00 AM the next day in the in-between weeks (18 hours) and 2:00 AM the next day in northern summer (17 hours).
Three Gaps and When Each Applies
Both cities change their clocks, in opposite seasons and on different dates, so there are three gaps in a year:
- 19 hours (PST and AEDT): from the first Sunday in November to the second Sunday in March.
- 17 hours (PDT and AEST): from the first Sunday in April to the first Sunday in October.
- 18 hours (PDT and AEDT): from the first Sunday in October to the first Sunday in November, and from the second Sunday in March to the first Sunday in April.
The 18-hour stretches are the weeks when only one of the two cities has changed its clocks, which makes them the easiest to miss.
Late Los Angeles Afternoon, Early Sydney Morning
The two 9-to-5 days don't overlap at all, so a live call means one side moves outside its normal hours. The best option is the end of the Los Angeles afternoon: at 17 hours, 4:00 to 5:00 PM is 9:00 AM to 10:00 AM the next day; at 18 hours, 3:00 to 5:00 PM is 9:00 AM to 11:00 AM the next day; at 19 hours, 2:00 to 4:00 PM is 9:00 AM to 11:00 AM the next day. In each case Sydney is at its desk the next morning.

| PDT → AEST: Both inside 9 AM–5 PM The narrowest window of the year. | |

| PDT → AEDT: Both inside 9 AM–5 PM The in-between weeks. | |
"Inside 9 AM–5 PM" is a planning assumption for a standard office day on each side, not a claim about any company's hours.
A Monday Afternoon Is a Tuesday Morning
A meeting set in Los Angeles time stays on that clock while Sydney's end moves, so a Monday 3:00 PM Los Angeles call is 10:00 AM the next day in Sydney at 19 hours and 8:00 AM the next day at 17 hours, both on Tuesday. Put the Sydney date in the invite as well as the time.
Going the other way, 9:00 AM in Sydney is 2:00 PM the previous day in Los Angeles at 19 hours and 4:00 PM the previous day at 17 hours, always the previous day. Use the date in the converter rather than a remembered gap of "17" or "19", since each is wrong for part of the year.
