What places in the town use a 24 hour clock?

In many towns, places that typically use a 24-hour clock include hospitals, military facilities, public transportation schedules (like train and bus timetables), and some airports. Additionally, certain businesses, such as convenience stores or restaurants that operate around the clock, may also display time in a 24-hour format. This format helps avoid confusion in time-sensitive environments, especially during early morning or late-night hours.
