What is the time difference between Korea and Hawaii?

Answer 1

The time in Hawaii has been UTC-10 since 8 Jun 1947.
The time in South Korea has been UTC+9 since 9 Oct 1988.
The time in North Korea has been UTC+8:30 since 15 Aug 2015.

So Hawaii is always 18.5 hours behind North Korea and 19 hours behind South Korea.

02:00 HAST (Hawaii-Aleutian Standard Time) =
20:30 KPT (North Korea Time) =
21:00 KRT (South Korea Time)

Answer 2

Korea is (Greenwich Mean Time) GMT +9 hours, ie. 9 hours ahead of Greenwich, England. Hawaii is (Greenwich Mean Time) GMT -10 hours, ie. 10 hours behind Greenwich, England. Hawaii is 19 hours behind Korea. (Daylight savings not taken into account.)

Answer 3

3 hrs behind calgary

It's 4 hrs if Calgary is on DST because Hawaii does not observe Daylight Saving Time.

Answer 4

Korea Standard Time (KST) is 19 hours ahead of Hawaii-Aleutian Standard Time (HST). Therefore, if it is noon in Hawaii, it would be 7:00 AM the next day in Korea.
