About the time in Cheonan
Sunrise today lands at 06:32 and sunset at 06:04 local time, giving 11h 32m of daylight. Those figures come from the city's own coordinates (36.81, 127.15) rather than a country-wide average, so they match what you would actually see from a window in Cheonan.
If you are coordinating from another country, the shortcut is the working window: a normal Cheonan 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.

The clock at the top of this page is not copied from your device: it is anchored to our reference timestamp and re-rendered every second against the IANA time zone database, so it stays right even when a laptop or phone has quietly drifted.
