Best time to call Los Angeles from Perth

Waking hours, 8 am–10 pm on each clock, overlap 8 am–2 pm in Perth, which is 4–10 pm the day before in Los Angeles.

That’s for a call outside work: catching someone before or after their working day. For a work call, the meeting hours above fit inside both working days.

The year ahead

One clock change moves the meeting this year. Each step is a week when one side has changed and the other hasn’t, or a season when the gap swaps.
