What is PKT in AST?
Atlantic Time is 8 hours behind
Pakistan Standard Time is on UTC+5:00 and Atlantic Time is on UTC−3:00 right now. Atlantic Time is on daylight saving, so its clocks read ADT. The gap changes during the year — see below.

When the difference changes
Pakistan Standard Time and Atlantic Time do not change their clocks on the same dates, so the gap between them is not the same all year. Most converters show only today’s figure. These are the periods ahead:
- Now – November 1, 2026Atlantic Time is 8 hours behind
- November 1, 2026 – March 14, 2027Atlantic Time is 9 hours behind
- March 14, 2027 – onwardsAtlantic Time is 8 hours behind
Periods shorter than a day are not listed. Each zone changes at its own local time, so on a date when both move there are a few hours when the gap is briefly something else.
Daylight saving
Pakistan Standard Time
Pakistan Standard Time stays on PKT all year, so its offset from UTC never moves.
Atlantic Time
Clocks go back one hour — 2:00 am becomes 1:00 am local time, and the zone is on AST after that.

Scheduling between the two
Working hours overlap from 5:00 pm to 6:00 pm PKT, which is 9:00 am to 10:00 am ADT. Anything inside that window falls in the normal working day at both ends.
A note on AST: it can also mean Arabia Standard Time (UTC+3). This page means Atlantic Time.
Atlantic Time (ADT) is used in Nova Scotia, New Brunswick and Puerto Rico
