What AKST and SGT Actually Are
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.
SGT — Singapore Time
Singapore. Standing at UTC+8:00 as written, and the region does not change its clocks, so that offset holds all year.
Singapore sits at a longitude that would put it near UTC+7, but moved to UTC+8 in 1982 to align with Malaysia and Hong Kong — a trade decision rather than a solar one.
What This Means in Practice
The date changes mid-working-day
For 8 of the eight hours in a normal AKST working day, the equivalent SGT 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 SGT 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 16 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.

Frequently Asked Questions
What is the time difference between AKST and SGT?

9:00 AM AKST is 1:00 AM the next day SGT.
What are the best hours to schedule a call between AKST and SGT?
Standard business hours in these two zones do not overlap at all, so one side has to work outside the 9-to-5. The most workable window is 3:00 PM to 10:00 PM AKST, which is 7:00 AM to 2:00 PM SGT.
