PKT to HST Time Converter
HST is 15 hours behind PKT. PKT is UTC+5:00, and HST is UTC-10:00.
Best Time to Call Between PKT and HST
Standard 9-to-5 hours in these two zones never overlap, so someone has to take the call outside their working day. The most workable window is 7:00 AM to 1:00 PM PKT, which is 4:00 PM to 10:00 PM HST.

What PKT and HST Actually Are
PKT — Pakistan Standard Time
Karachi, Lahore, Islamabad, Faisalabad. Standing at UTC+5:00 as written, and the region does not change its clocks, so that offset holds all year.
Pakistan tried daylight saving in 2008 and 2009 to ease electricity shortages, then dropped it after public objection.
HST — Hawaii Standard Time
Honolulu and the rest of Hawaii. Standing at UTC-10:00 as written, and the region does not change its clocks, so that offset holds all year. Hawaii does not observe daylight saving, so this offset holds all year.
Hawaii dropped daylight saving in 1967 and never resumed it. Being close to the equator, its daylight barely varies across the year, so there is little to gain.
What This Means in Practice
The date changes mid-working-day
For 6 of the eight hours in a normal PKT working day, the equivalent HST time falls on a different calendar date. Anything scheduled in that stretch needs the date checked as well as the time, or a Tuesday call quietly becomes a Wednesday one at the other end.
A gap you can rely on
Neither region changes its clocks, so this difference holds every day of the year. A recurring meeting booked once stays correct — worth knowing, because most cross-border pairs cannot say that.
Nearly opposite sides of the clock
At 15 hours apart, one side's morning is the other side's night. Handing work over at the end of a shift usually beats trying to get both parties in the same call.
