Los Angeles and the US West Coast use Pacific Time — Pacific Standard Time (PST, UTC−8) in winter and Pacific Daylight Time (PDT, UTC−7) in summer. The transition follows the same US schedule: forward in March, back in November. Silicon Valley operates in this timezone, making PT a reference point for the tech industry.
London uses Greenwich Mean Time (GMT, UTC+0) in winter and British Summer Time (BST, UTC+1) in summer. The UK clocks go forward one hour on the last Sunday of March and back on the last Sunday of October. GMT takes its name from the Royal Observatory in Greenwich, east London — the historical origin of UTC-based world time.
Both Los Angeles and London may observe Daylight Saving Time, which means the offset between them can change twice a year. Here is what to expect each season.
| Period | Note | Los Angeles | London | Offset |

| Mar – late Mar | US clocks forward, some zones still on standard | PDT (UTC−7) | GMT (UTC+0) | 7 hours |
| Late Mar – Oct current | Both on summer / daylight time | PDT (UTC−7) | GMT+1 (UTC+1) | 8 hours |
| Late Oct – early Nov | Clocks transitioning — check exact date | PST (UTC−8) | GMT (UTC+0) | 8 hours |
The transition window typically lasts 1–2 weeks in spring and autumn. If you have a recurring weekly meeting near a clock change, verify the exact date to avoid a missed call.
