Best Meeting Time: Los Angeles to London

Los Angeles and London sit 8 hours apart for most of the year, which means only one hour of standard working-day overlap exists between the two cities. That single hour, 9am to 10am Pacific and 5pm to 6pm GMT/BST, is the entire shared window. Anyone scheduling regular calls across this gap needs to understand it precisely before booking anything.

Working Across Los Angeles and London

The practical reasons for scheduling between Los Angeles and London are concentrated in a handful of sectors. Entertainment is the most obvious: major film studios and streaming platforms headquartered in Los Angeles have distribution, financing, and production partners across London's film and television industry. Rights negotiations, greenlight calls, and post-production co-ordination all cross this timezone gap regularly. Music is similar, with LA-based labels and management companies routinely dealing with London agents, promoters, and record companies. Finance is a second strong driver. Los Angeles has a significant asset management and private equity community, and London remains the largest financial centre in Europe. A Los Angeles fund manager with exposure to European markets, or a London investment bank with US clients on the West Coast, will need to schedule calls that work for both sides. Technology is growing as a connector. London's tech sector has expanded steadily, and many US technology companies treat their London office as the European headquarters. Product, engineering, and commercial teams in Los Angeles therefore have regular counterparts in London who need alignment. At the office level, the cultures differ. London office workers typically default to a 9am start, with lunch around 12:30pm to 1:30pm and a wind-down by 5:30pm on most days. Los Angeles media and tech offices tend to run later, with many teams starting at 10am Pacific to stay in sync with afternoon schedules in Asia, and running to 7pm. Friday afternoons in both cities are lighter: London often clears out by 4pm, and Hollywood production schedules frequently release staff early.

Time Difference: Los Angeles and London

London is currently 8 hours ahead of Los Angeles. The live offsets are Los Angeles UTC-7 and London UTC+1. Los Angeles observes daylight saving and London also observes daylight saving, so the offset shifts twice a year if both sides aren't already aligned.

In standard time, London is 8 hours ahead of Los Angeles. London sits at UTC+0 and Los Angeles at UTC-8 between November and March. Both cities observe daylight saving time, but their clock-change dates do not align in autumn, which creates a brief period each year when the gap is different from usual. In summer, when both cities are on DST, London moves to UTC+1 and Los Angeles to UTC-7, so the gap remains 8 hours. The complication comes in autumn. The UK moves its clocks back on the last Sunday of October, while the US moves back on the first Sunday of November. In the week between those two Sundays, London has already returned to UTC+0 while Los Angeles is still on UTC-7, producing a gap of 7 hours rather than 8. The standard 8-hour offset is restored once the US changes its clocks the following weekend. In spring the sequence reverses without a mismatch: the US changes clocks on the second Sunday in March and the UK changes on the last Sunday in March, so for that intervening week the gap is again 7 hours. In short, the gap narrows from 8 to 7 hours twice a year for approximately one week each time, once in mid-March and once in late October to early November.

Best Times to Meet

With only 1 hour of working-day overlap, the scheduling window between Los Angeles and London is narrow by any standard. The shared slot is 9am to 10am Pacific, which corresponds to 5pm to 6pm in London. That hour is the entire working-day meeting window. For the London side, 5pm to 6pm is a reasonable time to book: the working day is ending, but the hour is recognised as a legitimate slot, particularly in finance, where informal late-afternoon meetings are common. Avoid the 5pm slot on Fridays: London offices frequently wind down by 4pm on Fridays, and attendance at a 5pm call is less reliable that day. For the Los Angeles side, 9am is the open of the canonical working day, though many LA media and tech offices do not reach full attendance until 10am. A 9am Pacific call is therefore better suited to finance or legal professionals in Los Angeles than to entertainment or technology teams, who may not be fully available at that hour. If a meeting cannot be arranged within this 1-hour window, one side must accept a call outside their standard working hours. A 7am Pacific call places London at 3pm, well within their day. An 8pm London call puts Los Angeles at 12 noon, equally convenient, so asynchronous compromises around the midday Pacific slot are worth considering when the overlap window is already taken.

These conversions use the current UTC offsets: Los Angeles at UTC-7, London at UTC+1, giving an 8-hour difference. 9am Monday in Los Angeles = 5pm Monday in London. This is the start of the 1-hour working-day overlap and the most practical real-time slot for both sides. 12 noon Monday in Los Angeles = 8pm Monday in London. London is outside standard working hours; this would require explicit agreement from the London participant. 6pm Monday in Los Angeles = 2am Tuesday in London. This is the middle of the night in London and unusable for a live call without extraordinary circumstances. During the brief autumn or spring transition week when the gap narrows to 7 hours, those same 9am Pacific meetings land at 4pm in London rather than 5pm, which is actually more comfortable for London attendees.

Tips for Scheduling Across Los Angeles and London

• The 1-hour overlap lands at 9am Pacific and 5pm London: confirm both teams are actually working those hours before making it a standing slot.
• During the autumn clock-change week, the gap narrows to 7 hours, so a fixed 9am Pacific call will land at 4pm in London rather than 5pm.
• London offices tend to clear out by 4pm on Fridays; avoid booking the overlap slot on a Friday from the Los Angeles side.
• US Thanksgiving falls on a Thursday in November; UK colleagues won't know it's a holiday unless you tell them well in advance.
• A 12 noon Pacific call lands at 8pm in London: if you need London attendance, treat that as an out-of-hours ask and flag it explicitly.

Public Holidays and Working Weeks

Working-week patterns differ between the two cities in ways that affect scheduling beyond just the time offset. In London, most office workers default to a 9am start and are generally present through to 5:30pm. Fridays tend to wind down by 4pm, which means late-afternoon calls on Fridays stand a real chance of low engagement from the London side. Lunch in London offices typically runs from 12:30pm to 1:30pm: scheduling calls that land in that window for London should be avoided where possible. In Los Angeles, particularly in entertainment and technology, the working day often starts at 10am and can run to 7pm. Friday afternoons in Hollywood follow production schedules, which frequently release staff early, so the same Friday caution applies to LA as to London. On the holidays calendar, the two cities share Christmas Day on 25 December but little else. Los Angeles offices close for Independence Day on 4 July and for Thanksgiving, which falls on the fourth Thursday in November. Neither of those is observed in London. London offices close for New Year's Day on 1 January and for the May Bank Holiday on the first Monday in May, neither of which is a federal holiday in the US. The autumn US Thanksgiving period and the UK's May Bank Holiday are both traps for anyone with a standing weekly call: it is worth checking both calendars before setting a recurring meeting series, since a clash will eventually catch someone unprepared.
