0000 vs 2400 Military Time: Midnight and Noon

0000 starts a day; 2400 can mark its end. Learn why noon is 1200 and how midnight affects the date.

0000 means 12:00 AM at the beginning of a day. For example, 0000 on October 14 is the start of October 14. The date matters whenever you compare schedules across midnight.

2400 can mark 12:00 AM at the end of the stated day. 2400 on October 14 is the same instant as 0000 on October 15. This calculator accepts 2400 and 24:00 as next-day midnight. Values such as 2401 are invalid.

1200 is noon, or 12:00 PM. The hour after noon is 1300; the hour after midnight is 0100. For a time with minutes, 0030 is 12:30 AM while 1230 is 12:30 PM.
