Why people convert London to Los Angeles time
- Scheduling a call from London to Los Angeles: a 10:00 AM start in London lands at 2:00 AM in Los Angeles, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -8h gap: London and Los Angeles have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in Los Angeles is 1:00 AM in London.
- Watching a live event or market open: London viewers need 1:00 AM in Los Angeles to catch a 9:00 AM start there, and 8:00 AM if the event is anchored to London.
- Always state the zone abbreviation, not just the hour. "3:00 PM BST" is unambiguous; "3 PM" across a -8h gap is not.
- With a -8h gap there is no shared 9-to-5 window, so alternate the early start: one week London takes the early slot, the next week Los Angeles does.
- London: Clocks fall back on Sun, Oct 25, 2026. Re-check this page after that date because the offset changes and so does the -8h gap.
- Los Angeles: Clocks fall back on Sun, Nov 1, 2026. Any meeting series spanning that date will shift by an hour in local time.
