Time now in Sansu-ri

Sunrise today lands at 05:50 and sunset at 07:14 local time, giving 13h 24m of daylight. Those figures come from the city's own coordinates (37.71, 127.66) rather than a country-wide average, so they match what you would actually see from a window in Sansu-ri.

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

Sansu-ri sits at latitude 37.71, in the mid-latitude band, so day length here swings noticeably between midwinter and midsummer — today's 13h 24m is one point on that curve, not a fixed value.
