Comparing Time Zones: BST and SGT
BST runs on British Summer Time (BST) at UTC+01:00. SGT runs on Singapore Standard Time (SGT) at UTC+08:00. That puts BST 7 hours ahead of SGT — a difference of +7h at the current offsets.

Why people convert BST to SGT time
- Scheduling a call from BST to SGT: a 10:00 AM start in BST lands at 5:00 PM in SGT, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both BST and SGT are inside the 9-to-5 working day between 9:00 AM and 10:00 AM BST time (4:00 PM–5:00 PM SGT). That is roughly 1 hours of usable overlap.
- Watching a live event or market open: BST viewers need 4:00 PM in SGT to catch a 9:00 AM start there, and 5:00 PM if the event is anchored to BST.
- Always state the zone abbreviation, not just the hour. "3:00 PM BST" is unambiguous; "3 PM" across a +7h gap is not.
- Block 9:00 AM–10:00 AM BST as the recurring meeting window if you work primarily from BST and need SGT colleagues present.
About BST (British Summer Time)
British Summer Time (BST) is the daylight saving period in the United Kingdom, when clocks move one hour forward from Greenwich Mean Time (GMT, UTC+00:00) to UTC+01:00. It runs from the last Sunday in March to the last Sunday in October. England, Scotland, Wales and Northern Ireland all follow it, along with the Isle of Man and the Channel Islands of Jersey and Guernsey. During BST, London is one hour ahead of UTC, four hours ahead of New York on Eastern Daylight Time, and five hours ahead of New York once the United States returns to Eastern Standard Time in November. BST is also used to abbreviate Bangladesh Standard Time (UTC+06:00), which is listed separately on this site.
About SGT (Singapore Standard Time)
Singapore Standard Time (SGT) is used in Singapore year-round. Singapore does not observe daylight saving time. Despite being geographically close to the UTC+07:00 zone, Singapore uses UTC+08:00 to align with major trading partners like China, Hong Kong, and Malaysia. Singapore is a major global financial hub.
Best time to call between BST and SGT
Both BST and SGT sit inside the 9 AM – 5 PM working day between 9:00 AM–10:00 AM BST, which is 4:00 PM–5:00 PM SGT. That gives roughly 1 hours of shared time — the safest window for a live call or meeting.
Business hours overlap
BST and SGT overlap for only 60 minutes (9:00 AM–10:00 AM BST), so meetings have to be booked precisely.
BST is 7 hours ahead of SGT (BST UTC+01:00 → SGT UTC+08:00). The shared working window is 9:00 AM–10:00 AM BST. Remember to re-check around daylight-saving transitions.
