BST vs PKT: Offsets, DST and Best Call Times
BST runs on British Summer Time (BST) at UTC+01:00. PKT runs on Pakistan Standard Time (PKT) at UTC+05:00. That puts BST 4 hours ahead of PKT — a difference of +4h at the current offsets.

Why people convert BST to PKT time
- Scheduling a call from BST to PKT: a 10:00 AM start in BST lands at 2:00 PM in PKT, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both BST and PKT are inside the 9-to-5 working day between 9:00 AM and 1:00 PM BST time (1:00 PM–5:00 PM PKT). That is roughly 4 hours of usable overlap.
- Booking travel or deliveries: tracking PKT local time against BST keeps pickup windows and arrival estimates honest across the +4h offset.
- Always state the zone abbreviation, not just the hour. "3:00 PM BST" is unambiguous; "3 PM" across a +4h gap is not.
- Block 9:00 AM–1:00 PM BST as the recurring meeting window if you work primarily from BST and need PKT 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 PKT (Pakistan Standard Time)
Pakistan Standard Time (PKT) is the time zone used throughout Pakistan. PKT does not observe daylight saving time. Pakistan is the 5th most populous country in the world.
Best time to call between BST and PKT
Both BST and PKT sit inside the 9 AM – 5 PM working day between 9:00 AM–1:00 PM BST, which is 1:00 PM–5:00 PM PKT. That gives roughly 4 hours of shared time — the safest window for a live call or meeting.
Business hours overlap
BST and PKT overlap for about 4 hours during the working day — enough for meetings if you avoid the edges of the window.
BST is 4 hours ahead of PKT (BST UTC+01:00 → PKT UTC+05:00). The shared working window is 9:00 AM–1:00 PM BST. Remember to re-check around daylight-saving transitions.
