EST to AKST — Eastern to Alaska Time

Alaska Time is 4 hours behind Eastern Time, all twelve months.

The conversion rule

Subtract 4 hours from Eastern Time to get Alaska Time. 12:00 PM EST is 8:00 AM AKST. Alaska observes daylight saving on the same schedule as the East Coast (AKDT ↔ EDT), so the 4-hour spread is fixed.

Shared office hours are short: 1:00–5:00 PM ET / 9:00 AM–1:00 PM AKT. Book Anchorage calls in the Eastern afternoon; a 10:00 AM ET meeting would ring in Alaska at 6:00 AM.

Frequently asked questions

Does Alaska use daylight saving time?

Yes. Nearly all of Alaska is on AKST (UTC−9) in winter and AKDT (UTC−8) from the second Sunday of March to the first Sunday of November, matching the mainland's DST dates — which is why the gap to Eastern Time stays 4 hours.

What is 9:00 AM EST in Alaska?

5:00 AM AKST. The East Coast's whole morning happens before Anchorage starts its workday.

When is 12:00 PM AKST on the East Coast?

4:00 PM EST. An Alaska lunchtime call catches New York in its last business hour.
