PKT to EST

About Pakistan Standard Time

Pakistan is a fixed UTC+5. Two short daylight-saving experiments in 2002 and 2008–09 were abandoned, so nothing shifts now.

Cities on this clock: Tashkent, Almaty, Karachi, Lahore.

Watch out: Pakistan Standard Time is abbreviated PST locally, which is the same abbreviation as US Pacific Standard Time — thirteen hours away.

About Eastern Time

Eastern Time is the most populous North American zone and the one most business hours are quoted in. It is UTC−5 as EST and UTC−4 as EDT. Because it changes on US dates rather than European ones, its gap to London and to Central Europe is not constant — there are two short stretches each year when it is an hour narrower than usual, and they are the reason this pair's table has more than one row.

Cities on this clock: New York, Philadelphia, Boston, Miami, Atlanta, Toronto, Montreal, Ottawa.

How the difference is worked out

The gap between Pakistan Standard Time and Eastern Time is not one number. The two zones change their clocks on different dates, so for part of the year the difference is 9 hours and for the rest it is something else — the table above lists each stretch of 2026 with the date it starts and which country's clocks moved.

With both zones on their own standard time — daylight saving not in force anywhere — Eastern Time is 10 hours behind Pakistan Standard Time. That figure never changes; everything else on this page follows from it plus whichever clocks have moved.

Every figure here comes from the IANA time zone database via your browser's own Intl engine, using the zone ids Asia/Karachi and America/New_York. Nothing is looked up on a server and nothing about your visit is recorded.
