Korea has many small rules about opening days: most museums close on Mondays, Gyeongbokgung on Tuesdays, and when a closing day falls on a public holiday it often moves to the next business day. Map apps rarely show this, and Google Maps hours in Korea are often missing. This site reads the official listings and works out, day by day, whether a place is open.
Data is refreshed daily. When a closing-day note cannot be read as a clear rule we show “Check” instead of guessing.
