Understanding the -4h Gap: PKT vs BST
PKT runs on Pakistan Standard Time (PKT) at UTC+05:00. BST runs on British Summer Time (BST) at UTC+01:00. That puts PKT 4 hours behind BST — a difference of -4h at the current offsets.
In practice, when it is 9:00 AM in PKT it is 5:00 AM in BST. Midnight in PKT is 8:00 PM in BST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert PKT to BST time
- Scheduling a call from PKT to BST: a 10:00 AM start in PKT lands at 6:00 AM in BST, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both PKT and BST are inside the 9-to-5 working day between 1:00 PM and 5:00 PM PKT time (9:00 AM–1:00 PM BST). That is roughly 4 hours of usable overlap.
- Watching a live event or market open: PKT viewers need 5:00 AM in BST to catch a 9:00 AM start there, and 4:00 AM if the event is anchored to PKT.
- Always state the zone abbreviation, not just the hour. "3:00 PM PKT" is unambiguous; "3 PM" across a -4h gap is not.
- Block 1:00 PM–5:00 PM PKT as the recurring meeting window if you work primarily from PKT and need BST colleagues present.
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.
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.
Best time to call between PKT and BST
Both PKT and BST sit inside the 9 AM – 5 PM working day between 1:00 PM–5:00 PM PKT, which is 9:00 AM–1:00 PM BST. That gives roughly 4 hours of shared time — the safest window for a live call or meeting.
Business hours overlap
PKT and BST overlap for about 4 hours during the working day — enough for meetings if you avoid the edges of the window.
PKT is 4 hours behind BST (PKT UTC+05:00 → BST UTC+01:00). The shared working window is 1:00 PM–5:00 PM PKT. Remember to re-check around daylight-saving transitions.
