The 24-Hour Format Converter is used to effortlessly convert a 12-hour time format that is commonly by the world, to a 24-hour format. In a 12-hour clock, every single day, the time starts at midnight at 12:00 AM and ends at 12:00 AM. On the other hand, using a 24-hour clock, a day starts at 00:00 and ends at 24:00.
The 24-hour clock is a way of telling the time in which the day runs from midnight to midnight and is divided into 24 hours, numbered from 1 or 0 to 24 or 23. It does not use a.m. or p.m.
