Convert PKT to IST

IST is 30 minutes ahead of PKT. PKT is UTC+5 and IST is UTC+5:30.

Which IST is this?

IST names more than one zone. This page reads it as India Standard Time at UTC+5:30, which is the reading most converters take. There are others: Israel Standard Time at UTC+2, used in Israel in winter; Irish Standard Time at UTC+1, used in Ireland in summer.

The letters on a meeting invitation do not say which one is meant. If yours is not India Standard Time, the answer above is wrong, and not by a little:

The large converter sites disagree about this as well: search for a IST conversion and some of the results answer for one reading and some for another, none of them saying which they chose. Where it matters, ask which country the sender is in rather than which letters they typed.

Best time to schedule a meeting

Standard 9–5 working hours overlap for 8 hours: 9:00 AM–5:00 PM PKT (9:00 AM–5:00 PM IST). Schedule meetings inside that window.

About PKT

Pakistan Standard Time (PKT) is UTC+5. It is used in Pakistan, all year.

Pakistan Standard Time is UTC+5 and does not change through the year — daylight saving has been tried twice and abandoned twice. It sits half an hour behind India, which is the only pair of neighbouring countries in the region separated by a half-hour step rather than a whole one, and a common source of missed calls across that border.

About IST

India Standard Time (IST) is UTC+5:30. It is used in all of India and Sri Lanka, on a half-hour offset.

India Standard Time is UTC+5:30 — one of the handful of zones offset by half an hour, which breaks any code that assumes whole-hour offsets and any mental arithmetic that does the same. India has no daylight saving and one time zone for the entire country, despite spanning nearly 30 degrees of longitude. The abbreviation is also used for Irish Standard Time and Israel Standard Time, both of which are entirely different offsets.

Does this gap change with the seasons?

Neither PKT nor IST shifts with the seasons, so this 0.5-hour difference holds all year. That is unusual enough to be worth relying on: most cross-continental gaps move twice a year.

This is the reason scheduling systems store an IANA zone such as Region/City rather than an offset or an abbreviation: the zone knows its own rules and the offset does not.
