Singapore uses Singapore Time (SGT, UTC+8) year-round with no Daylight Saving Time. Singapore is situated near the equator, which means daylight hours barely vary throughout the year, making DST unnecessary. SGT aligns with Kuala Lumpur (MYT), Hong Kong (HKT), and China (CST).
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 Singapore 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 | Singapore | London | Offset |
|---|---|---|---|---|
| Nov – Mar | Both on standard time | GMT+8 (UTC+8) | GMT (UTC+0) | 8 hours |
| Mar – late Mar | US clocks forward, some zones still on standard | GMT+8 (UTC+8) | GMT (UTC+0) | 8 hours |
| Late Mar – Oct current | Both on summer / daylight time | GMT+8 (UTC+8) | GMT+1 (UTC+1) | 7 hours |
| Late Oct – early Nov | Clocks transitioning — check exact date | GMT+8 (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.
