About the time in Osan
If you are coordinating from another country, the shortcut is the working window: a normal Osan 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.
Sunrise today lands at 05:52 and sunset at 07:17 local time, giving 13h 25m of daylight. Those figures come from the city's own coordinates (37.15, 127.07) rather than a country-wide average, so they match what you would actually see from a window in Osan.
The zone identifier Asia/Seoul is the value you want in code, calendars and travel systems. Abbreviations change with the season, but Asia/Seoul keeps pointing at Seoul time whatever the date, which is why every timestamp on this page is built from it.
