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 (37.42, 127.13) rather than a country-wide average, so they match what you would actually see from a window in Seongnam-si.
Seongnam-si runs on Asia/Seoul, which puts the city UTC +9 from Coordinated Universal Time right now. 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.
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.
