Hour-by-Hour Comparison
Time Difference: Los Angeles to London
This page shows the live time conversion between Los Angeles and London. The hour-by-hour chart above makes it easy to find overlapping business hours for meetings or calls. Green highlights indicate standard business hours (9 AM – 5 PM) in each city.
The 8-Hour Atlantic-Pacific Gap
Los Angeles and London are separated by 8 hours during winter (7 during mutual DST periods). This is wider than the New York-London gap by 3 hours, making LA-London coordination significantly more challenging. When London opens at 9 AM GMT, LA is at 1 AM PT — dead of night. The entire London business day passes before LA even wakes up.
The Narrow Window
The realistic overlap is tight: 8-10 AM PT catches 4-6 PM GMT. That's the end of London's day meeting the start of LA's day. Most LA-London teams protect this 2-hour window for synchronous meetings and handle everything else asynchronously. A 7 AM PT call catches London at 3 PM — more breathing room for London but early for LA.
Entertainment & Media
The LA-London entertainment axis is significant — US studios co-produce with UK talent, British actors work in Hollywood productions, and streaming platforms serve both markets. Film distribution, marketing campaigns, and press junkets require daily coordination. The time gap means London-based entertainment PR teams often work late to accommodate LA schedules.
Scheduling Tips
If you're in LA and need London: get an early start. Calls at 7-8 AM PT catch London at 3-4 PM — ideal. If you're in London and need LA: be prepared for late afternoon or evening calls. 5 PM GMT catches LA at 9 AM PT — the very start of their day. The bottom line: someone has to flex, and sustainable LA-London collaboration requires sharing that burden across the week.
