PST to GST Time Converter

GST is 11 hours ahead of PST. The US West Coast is currently on PDT (UTC-7:00), and GST is UTC+4:00.

Worth knowing right now. The US West Coast is currently on PDT, not PST, because daylight saving is in effect. The 11 hours above is the gap between those two regions today, which is almost certainly what you want. Taken strictly as written, PST to GST is 12 hours.

What PST and GST Actually Are

PST — Pacific Standard Time

Los Angeles, San Francisco, Seattle, Las Vegas, Vancouver. Standing at UTC-8:00 as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, November 1, 2026, to PST. The Philippines occasionally uses PST for Philippine Standard Time (UTC+8); PHT is the clearer label for that.

California voted in 2018 to move to permanent daylight time, but the change needs an act of Congress and has never happened, so PST is still the winter standard.

GST — Gulf Standard Time

Dubai, Abu Dhabi, Sharjah, Muscat. Standing at UTC+4:00 as written, and the region does not change its clocks, so that offset holds all year. GST also refers to South Georgia Time (UTC-2), which you are very unlikely to want.

The Gulf states have never observed daylight saving, so Dubai's offset has been unchanged for decades — unusual stability for a region that grew as fast as it did.

What This Means in Practice

The date changes mid-working-day

For 4 of the eight hours in a normal PST working day, the equivalent GST 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.

This gap is not fixed

PST changes its clocks and GST does not, so the difference between them moves by an hour twice a year. A recurring meeting set now will drift for one side from Sunday, November 1, 2026 unless someone resets it.

Nearly opposite sides of the clock

At 11 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.
