Time zone comparison
British Summer Time (BST, UTC+01:00) vs Singapore Time (SGT, UTC+08:00). Right now BST is 7h behind SGT. BST is used in London, Birmingham and Manchester while SGT covers Singapore. Use the 24-hour grid below to find a meeting slot both sides will tolerate.
Heads up: these zones diverge on daylight saving.
BST observes DST while SGT does not, so the gap shifts by an hour twice a year. In January the difference is 8h, in July it is 7h. If you are scheduling across the spring or autumn transitions, double-check the date.
Hours where both sides sit inside 9-to-5 business hours.
Both in business hours

Each row is one hour. Green rows are when both sides are inside 9 AM to 5 PM.

British Summer Time (BST) sits at UTC+01:00 today, while Singapore Time (SGT) is at UTC+08:00. The current gap is 7 hours, with BST behind SGT. In practical terms, if your morning starts at 9 AM in London, your counterpart in Singapore is seeing 16:00 on their own watch at that exact moment.
BST is the working clock for London, Birmingham and Manchester. BST also refers to Bangladesh Standard Time (Asia/Dhaka). UK usage dominates search volume. SGT covers Singapore. If your team is split between these two regions, the table above is the quickest way to spot the daily overlap window without doing the offset arithmetic in your head.
Daylight saving matters here. British Summer Time shifts forward an hour on the second Sunday of March (US) or the last Sunday of March (Europe) and back on the first Sunday of November or last Sunday of October. Singapore Time stays on a fixed offset year-round. The IANA tzdata baked into this page handles every transition automatically, so the table reflects the correct wall-clock times for today's date. For dates further out, use the converter linked above and pick the target date explicitly.
Common scheduling traps are easy to avoid here. Pick a wall-clock time on one side, read the matching wall-clock on the other from the table, and write both into the calendar invite, never just the difference. If the meeting falls in the week of a DST changeover and one of these zones shifts, the absolute clock will drift by an hour from what the recipient expects. The table is computed for today's date, so for a future meeting open the converter linked above and pick the exact date.
One last note for asynchronous teams: business-hour overlap is the wrong metric for handoff workflows. If you operate on a follow-the-sun model, you actually want zero overlap, with one team logging off as the other starts. BST and SGT differ by 7 hours, which is close to an ideal handoff window.
