GST to AKST Time Converter

AKST is 12 hours behind GST. GST is UTC+4:00, and Alaska is currently on AKDT (UTC-8:00).

Worth knowing right now. Alaska is currently on AKDT, not AKST, because daylight saving is in effect. The 12 hours above is the gap between those two regions today, which is almost certainly what you want. Taken strictly as written, GST to AKST is 13 hours.

What GST and AKST Actually Are

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.

AKST — Alaska Standard Time

Anchorage, Fairbanks, Juneau. Standing at UTC-9:00 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 AKST.

Alaska compressed four time zones into one in 1983, moving most of the state onto a single clock to keep business hours aligned with the rest of the country.

What This Means in Practice

The date changes mid-working-day

For 3 of the eight hours in a normal GST working day, the equivalent AKST 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

AKST 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 12 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.
