Los Angeles to Sydney Time

Los Angeles (United States) is a global financial and tech hub, with key industries in technology, finance, healthcare, and entertainment. Sydney (Australia) is a stable, resource-rich economy in the Asia-Pacific region, known for mining, agriculture, finance, and tourism. With a 18-hour time difference, professionals frequently schedule cross-border calls between these two cities for international trade, remote team collaboration, and client meetings.

Scheduling Meetings Between Los Angeles and Sydney

With Sydney 18 hours ahead of Los Angeles, there is minimal overlap in standard business hours. Most teams alternate meeting times to share the burden of early-morning or late-evening calls fairly. US business hours typically run 9 AM–5 PM, with a culture that values punctuality and efficiency. Australian work culture values work-life balance, with typical hours of 9 AM–5 PM and flexible arrangements common. Consider recording meetings for those who can't attend live, and use shared documents for async collaboration.

Daylight Saving Time Considerations

Both Los Angeles and Sydney observe Daylight Saving Time. Los Angeles uses PST/PDT (switching between standard and daylight time), while Sydney uses AEST/AEDT. If their DST transitions happen on different dates — which is common, as the US, EU, and other regions change clocks on different weekends — the effective time difference between the two cities can shift by 1 hour for several weeks. Always double-check the actual offset during March–April and October–November.

PST (PST/PDT) stands for the timezone used in Los Angeles, United States (UTC-8). AEST (AEST/AEDT) is the timezone used in Sydney, Australia (UTC+10). Los Angeles is 18 hours behind Sydney.

To convert PST to AEST, add 18 hours to PST time. For example, PST 9:00 AM = AEST 3:00 AM.
