Hours labelled in London local time.
No shared hours. A standard London workday and a standard Los Angeles workday never coincide, which is why the bar above is empty. The table below shows how close the two get.

Best time to call Los Angeles from London
A standard 9:00–17:00 day in London does not intersect a standard day in Los Angeles at all. Los Angeles is 8 hours behind London. Whoever joins the call is stepping outside their working hours, so the fair thing is to alternate who takes the inconvenient slot.
The least disruptive options are the edges: early morning in London before Los Angeles finishes for the evening, or late afternoon in London once Los Angeles is starting the next day. Anything in the middle lands in someone's night.
Cross-timezone workday overlap and collaboration
With so little shared time, London and Los Angeles work best as an asynchronous pair with one synchronous exception. Write decisions down as they are made rather than saving them for a call, because the next chance to talk is a day away.
Treat the gap as a handoff rather than a delay. Whoever finishes first should leave the next step written down and unambiguous; 8 hours later the other side picks it up without needing to ask a question that would cost another full day.
Watch for fatigue on recurring meetings. A weekly call that sits at the very edge of someone's evening is tolerable once and corrosive after a month. If the only workable slot is uncomfortable for one side, rotate it, or accept that the meeting should be a document instead.
Practical rules for this pairing
- Rotate who takes the out-of-hours call, rather than defaulting to the same side every week.
- Move status updates into writing entirely — there is no hour where a live update is cheap for both sides.
- If the pairing is permanent, a split shift on one side buys back a real overlap.
Frequently asked questions (London & Los Angeles)
What is the current time difference between London and Los Angeles?
Los Angeles is 8 hours behind London. That gap is calculated from the live IANA time zone database, so it already accounts for whichever daylight-saving rules are in force today rather than assuming a fixed offset.
What is the best window for a one-hour team sync between London and Los Angeles?
There is no window where a standard 9:00–17:00 day in London overlaps one in Los Angeles, so a one-hour sync has to sit outside someone's working hours. Alternate which side absorbs it, or replace the meeting with a written handoff.
Do London and Los Angeles change their clocks on the same date?
No. London changes on Sun, Oct 25 and Los Angeles on Sun, Nov 1. Between those two dates the usual difference is off by an hour, which is the period recurring meetings quietly drift in.
How many hours do London and Los Angeles actually share in a working day?
None. A standard 9:00–17:00 day in London and the same in Los Angeles do not intersect, which is why teams spanning these two cities usually adopt a split shift on one side.
