0000 Military Time

0000 military time means 12:00 AM (midnight), and it represents the start of the first hour of the day. It shows when the 24-hour clock goes back to zero. This helps clear up any confusion about midnight. 0000 is the preferred format in the military, aviation, healthcare, and computing. You may also see 2400 used in some timetables, while it represents the same moment in real time, its purpose is different:

0000 = the beginning of a day
2400 military time = the end of a day

For Example: A shift that ends exactly at midnight is noted as 2400, and a shift that begins at midnight starts at 0000. Both values are correct in their context, but 0000 is the standard format used in various sectors.
