Sunrise and Sunset in Seoul

Understanding sun times in Seoul

The sunrise and sunset times for Seoul on this page are computed from Seoul's geographic coordinates (37.57° latitude, 126.98° longitude) using the standard solar geometry equations. Times are returned in South Korea's local time zone (Asia/Seoul), so they automatically reflect daylight saving time when applicable.

What are dawn and dusk?

Dawn is the start of morning twilight, when the Sun is 6° below the horizon. This is when the sky first begins to lighten — useful for planning outdoor photography and travel. Dusk is the symmetrical point in the evening, marking the end of civil twilight.

Golden hour & blue hour

The golden hour—roughly the first hour after sunrise and the last hour before sunset—produces warm, soft, low-angle light that photographers prize. The blue hour, just before sunrise and just after sunset, gives deep blue skies ideal for cityscapes and moody portraits. Both are tied to the Sun's position relative to the horizon, not to clock time.
