Time now in Naedang-dong

Naedang-dong sits at latitude 35.86, in the mid-latitude band, so day length here swings noticeably between midwinter and midsummer — today's 13h 15m is one point on that curve, not a fixed value.

Sunrise today lands at 05:51 and sunset at 07:05 local time, giving 13h 15m of daylight. Those figures come from the city's own coordinates (35.86, 128.56) rather than a country-wide average, so they match what you would actually see from a window in Naedang-dong.

If you are coordinating from another country, the shortcut is the working window: a normal Naedang-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.
