What’s the 24-hour clock
The 24-hour clock is commonly used in timetables and where space is restricted. It is used without ‘am’ or ‘pm’.
The 24-hour clock is a convention of time keeping in which the day runs from midnight to midnight and is divided into 24 hours. The 24-hour clock starts at midnight (00:00) and indicates the hours passed, from 0 to 23.
It is the most common system in use in the world, and is the international standard notation of time. (ISO 8601)
