Yanggang-do, North Korea

Current time in Yanggang-do, North Korea

The displayed local time applies across Yanggang-do, including the provincial capital Hyesan, the city of Samjiyon, and the province’s rural counties. North Korea uses one national time zone, so crossing into Yanggang-do from another part of the country does not require changing the clock.

To convert the time manually, add nine hours to UTC. When that addition passes midnight, Yanggang-do is already on the following calendar date. This date difference matters when arranging calls, recording events, or comparing a local timetable with one published abroad. A clock may be national, but sunrise still keeps a strictly local appointment.

Time zone and daylight saving

Yanggang-do uses Korea Standard Time, commonly abbreviated KST. Its fixed offset is UTC+9. There is no seasonal clock change, so the relationship between Yanggang-do and UTC is simple and predictable.

The difference between Yanggang-do and another place can still change if that other place observes daylight saving time. A European or North American city may move its clock forward or back while Yanggang-do remains on KST. For recurring international plans, check the other location’s offset on the intended date.

Standard time zone: Korea Standard Time Abbreviation: KST UTC offset: UTC+9 Daylight saving time: not observed Clock changes within the province: none Phone and computer clocks normally identify the area through a North Korean or Pyongyang time-zone setting. A fixed UTC+9 setting gives the same clock reading, but a named regional zone is preferable because it preserves the geographic context.

Hyesan, Samjiyon, and local daylight

Hyesan is the capital and principal urban reference point for Yanggang-do. Samjiyon is another city in the province and lies farther north and west. County seats such as Pochon, Unhung, Kimhyonggwon, and Kimjongsuk share exactly the same civil time.

These places do not necessarily see sunrise at the same instant. Longitude affects when the Sun reaches the horizon, while latitude strongly influences seasonal day length. Terrain matters too: Yanggang-do is mountainous, and a ridge can delay the first direct sunlight visible from a valley even after the calculated sunrise.

Sunrise is therefore a daily astronomical value, not a permanent property of the time zone. For an accurate result, select the settlement or coordinates and the required date. A result calculated for Hyesan is a useful provincial reference, but it should not be treated as the exact visible sunrise in every mountain community.

Choose Hyesan, Samjiyon, or the relevant county seat. Enter the date for which daylight matters. Use local KST when reading the result. Allow for hills or buildings if actual first sunlight is important.
