Three seasons, not two

California moves its clocks forward on the second Sunday in March and back on the first Sunday in November (US Department of Transportation). New South Wales does the opposite season: forward on the first Sunday in October and back on the first Sunday in April, as published by the NSW Government.

Put together, that gives 19 hours while Los Angeles is on PST and Sydney on AEDT, 17 hours while Los Angeles is on PDT and Sydney on AEST, and 18 hours for the two in-between stretches, from the second Sunday of March to early April and from early October to the first Sunday of November. The dated list shows each stretch for this year and next.

Each Pacific hour with the Sydney time for every combination of seasons. Nearly every row is on the next day in Sydney (+1).

Meeting between California and Sydney

The working days barely touch, so most teams use the Californian afternoon and the Sydney morning of the next day. 3:00 PM in Los Angeles is 10:00 AM the next day in Sydney during the 19-hour season and 8:00 AM during the 17-hour season.

Remember the weekend shift: Friday afternoon in California is already Saturday morning in Sydney, and Monday morning in Sydney is still Sunday in California.

Before you schedule

  • Check which of the three gaps applies on the meeting date.
  • For Brisbane, ignore Australian daylight saving: Queensland stays on AEST, see the Brisbane clock.
  • Recheck recurring calls four times a year, after each country's two changes.
  • Use the live Sydney and Melbourne clocks for the time right now.
  • Starting from Sydney? Use AEST to PST.

PST to AEST questions

How many hours ahead of Los Angeles is Sydney?

It depends on the date: 19 hours in the northern winter, 17 hours in the northern summer, and 18 hours for a few weeks around March–April and October–November when only one side is on daylight time.

What time is it in Sydney at 3:00 PM in Los Angeles?

It is the next day in Sydney: 10:00 AM with a 19-hour gap, 9:00 AM with 18 hours and 8:00 AM with 17 hours.

Why does the PST to AEST gap have three values?

The US and Australia are in opposite hemispheres. California is on daylight time from March to November and Sydney from October to April, so there are stretches when both, one or neither are on summer time.

Does all of Australia change clocks with Sydney?

No. Queensland, Western Australia and the Northern Territory do not use daylight saving, so Brisbane, Perth and Darwin keep the same offset all year.

Is there a quick way to convert Pacific to Sydney time?

Subtract 5, 6 or 7 hours from the Los Angeles time and move to the next day, for gaps of 19, 18 and 17 hours.
