Paris (and all of metropolitan France) uses Central European Time (CET, UTC+1) in winter and Central European Summer Time (CEST, UTC+2) in summer. EU clocks change on the last Sunday of March and the last Sunday of October, the same schedule as most of continental Europe.
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 Paris 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 | Paris | London | Offset |
|---|---|---|---|---|
| Nov – Mar | Both on standard time | GMT+1 (UTC+1) | GMT (UTC+0) | 1 hour |
| Mar – late Mar | US clocks forward, some zones still on standard | GMT+1 (UTC+1) | GMT (UTC+0) | 1 hour |
| Late Mar – Oct current | Both on summer / daylight time | GMT+2 (UTC+2) | GMT+1 (UTC+1) | 1 hour |
| Late Oct – early Nov | Clocks transitioning — check exact date | GMT+1 (UTC+1) | GMT (UTC+0) | 1 hour |
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.

Both Paris and London observe Daylight Saving Time, but their transitions may not happen on the same date. During the brief 1–2 week windows in spring and autumn when only one zone has changed clocks, the offset between the two cities shifts by one hour. For most of the year the difference is 1 hour, but double-check the transition dates if you have a recurring meeting scheduled near those windows.
