Current time in Nampo, North Korea

The displayed clock gives the current local time for Nampo. North Korea does not currently observe daylight saving time, so clocks in the city do not move forward in spring or backward in autumn. For conversion, add nine hours to Coordinated Universal Time. The date can also change during conversion: when it is late afternoon in London, for example, Nampo may already have entered the next calendar day.

Time zone: Korea Standard Time UTC offset: UTC+9 Seasonal clock changes: none Same national time as Pyongyang A harbor may wait for the tide, but its clocks still keep standard time.

Nampo and its urban area

Nampo is a special city on North Korea’s western side, near the mouth of the Taedong River. It is an important reference point for the surrounding coastal and river landscape. Local names may appear in several Romanized forms, including Nampo, Nampho, and Namp’o; those spellings do not indicate different time zones.

The wider municipality includes central Nampo and surrounding districts and counties. Onchon and Ryonggang are useful place names when checking locations within the administrative area. A clock attached to any of these places should show the same civil time as central Nampo.

Pyongyang lies inland to the northeast and also uses UTC+9. Therefore, travel or communication between the capital and Nampo requires no clock adjustment. Differences in daylight are caused by position and landscape, not by an administrative time boundary.

Sunrise and daylight in Nampo

Sunrise is calculated for a particular date and location. Nampo’s western coastal position affects when the Sun appears compared with places farther east, even though their clocks agree. Sunset and total daylight also change as the year progresses.

Check that the sunrise date matches the date shown on the local clock. Use Nampo rather than a distant national reference point when timing dawn. Allow for hills, buildings, haze, and the visible horizon when planning an observation.

Remember that civil sunrise is a calculation; direct sunlight may reach a specific street later. The longest daylight occurs around the northern summer, while winter brings later sunrises and shorter days. Daily changes are gradual, so a time copied from another month is unsuitable for a precise morning plan.

Questions and answers

Is Nampo in the same time zone as Pyongyang?
Yes. Both use Korea Standard Time, which is UTC+9.
Does Nampo change its clocks for summer?
No. Daylight saving time is not currently observed in North Korea.
Why can Nampo and an eastern city have different sunrise times?
Sunrise depends on longitude, latitude, date, and the local horizon. A shared time zone does not make daylight begin simultaneously everywhere.
