What is the normal time difference between London and Los Angeles?

London is usually 8 hours ahead of Los Angeles. London observes GMT (UTC+0) in winter and BST (UTC+1) in summer; Los Angeles observes PST (UTC-8) in winter and PDT (UTC-7) in summer. Both cities shift clocks in spring and autumn, keeping the gap at 8 hours for most of the year.

When is the time difference only 7 hours?

There are two brief windows each year — typically one or two weeks in spring and two or three weeks in autumn — when the US and UK change their clocks on different weekends. During those windows the gap can be 7 hours. This tool shows the real offset live so you always have the correct number.

When does the UK change its clocks?

The UK moves clocks forward on the last Sunday in March at 01:00 GMT (becoming BST, UTC+1) and back on the last Sunday in October at 02:00 BST (returning to GMT, UTC+0).

When does Los Angeles (US West Coast) change its clocks?

The US shifts clocks forward on the second Sunday in March at 02:00 PST (becoming PDT, UTC-7) and back on the first Sunday in November at 02:00 PDT (returning to PST, UTC-8).

What are good meeting times for both London and Los Angeles?

With the standard 8-hour offset, the best overlap is 17:00–18:00 London time (09:00–10:00 Los Angeles time). The meeting overlap finder on this page highlights those windows automatically.

Is this tool accurate for scheduling?

Yes. It uses the IANA timezone database embedded in your browser — the same source used by operating systems and calendar apps worldwide. Accuracy depends on your device clock being synchronized via NTP, which most devices do automatically.

How it works

Your browser reads the current moment from your device clock.
It converts that moment to Europe/London time using the IANA timezone database built into modern browsers.
The same moment is converted to America/Los_Angeles time.
The UTC offsets of both cities are compared to calculate the exact hour difference.
All three values — London time, Los Angeles time, and the offset — refresh every second.
DST transitions for both cities are handled automatically, so the offset switches correctly each spring and autumn.
