São Paulo uses Brasília Time (BRT, UTC−3) and previously observed summer time (BRST, UTC−2), but Brazil abolished Daylight Saving Time in 2019. The offset is now a fixed UTC−3 year-round, making Brazilian time scheduling simpler and more predictable for international teams.
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 Sao Paulo 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 | Sao Paulo | London | Offset |
|---|---|---|---|---|
| Nov – Mar | Both on standard time | GMT-3 (UTC−3) | GMT (UTC+0) | 3 hours |
| Mar – late Mar | US clocks forward, some zones still on standard | GMT-3 (UTC−3) | GMT (UTC+0) | 3 hours |
| Late Mar – Oct current | Both on summer / daylight time | GMT-3 (UTC−3) | GMT+1 (UTC+1) | 4 hours |
| Late Oct – early Nov | Clocks transitioning — check exact date | GMT-3 (UTC−3) | GMT (UTC+0) | 3 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.
