PKT and HST on the World Map
The map below highlights the PKT (Pakistan Standard Time) and HST (Hawaii Standard Time) timezone regions across the globe.
PKT – Pakistan Standard Time
UTC+05:00Pakistan Standard Time (PKT) is the time zone for Pakistan, 5 hours ahead of UTC.
- •Pakistan does not observe daylight saving time.
- •Karachi is one of the world's most populous cities.
- •PKT is the same offset as Uzbekistan (UZT) and Yekaterinburg (YEKT).
HST – Hawaii Standard Time
UTC-10:00Hawaii Standard Time (HST) is the time zone for the Hawaiian Islands, 10 hours behind UTC.
- •Hawaii does not observe daylight saving time.
- •HST is 5 hours behind EST in winter and 6 hours behind EDT in summer.
- •Hawaii is one of only two US states that don't observe DST (the other is Arizona).
Understanding the -15h Gap: PKT vs HST
PKT runs on Pakistan Standard Time (PKT) at UTC+05:00. HST runs on Hawaii Standard Time (HST) at UTC-10:00. That puts PKT 15 hours behind HST — a difference of -15h at the current offsets.
In practice, when it is 9:00 AM in PKT it is 6:00 PM in HST on the previous day. Midnight in PKT is 9:00 AM in HST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert PKT to HST time
- Scheduling a call from PKT to HST: a 10:00 AM start in PKT lands at 7:00 PM in HST the previous day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -15h gap: PKT and HST have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in HST is 6:00 PM in PKT.
- Booking travel or deliveries: tracking HST local time against PKT keeps pickup windows and arrival estimates honest across the -15h offset.
- Always state the zone abbreviation, not just the hour. "3:00 PM PKT" is unambiguous; "3 PM" across a -15h gap is not.
- With a -15h gap there is no shared 9-to-5 window, so alternate the early start: one week PKT takes the early slot, the next week HST does.

Best time to call between PKT and HST
With a -15h offset there is no overlap inside a normal 9 AM – 5 PM day. HST opens at 9:00 AM HST, which is 6:00 PM in PKT, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
PKT and HST have no shared working hours because of the -15h gap. Teams need to alternate early starts or rely on asynchronous handovers.
PKT is 15 hours behind HST (PKT UTC+05:00 → HST UTC-10:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
