Time now in Sŏngyo 3-dong

Sunrise today lands at 05:57 and sunset at 07:22 local time, giving 13h 26m of daylight. Those figures come from the city's own coordinates (39.01, 125.76) rather than a country-wide average, so they match what you would actually see from a window in Sŏngyo 3-dong.

If you are coordinating from another country, the shortcut is the working window: a normal Sŏngyo 3-dong day of 09:00–17:00 falls between 00:00–08:00 UTC. Convert your own hours into UTC once and you can tell at a glance whether someone there is likely to be at their desk.

Sŏngyo 3-dong sits at latitude 39.01, in the mid-latitude band, so day length here swings noticeably between midwinter and midsummer — today's 13h 26m is one point on that curve, not a fixed value.
