Time can be displayed in 12-hour or 24-hour format.
12-hour to 24-hour conversion:
- 12:00 AM (midnight) = 00:00
- 12:30 AM = 00:30
- 1:00 AM = 01:00
- 12:00 PM (noon) = 12:00
- 1:00 PM = 13:00
- 6:00 PM = 18:00
- 11:59 PM = 23:59
Quick rule:
- AM hours (except 12 AM): same number
- 12 AM = 00 (midnight)
- PM hours: add 12 (1 PM = 13, 2 PM = 14, etc.)
- 12 PM stays 12 (noon)
Military time is the same as 24-hour format but spoken differently:
- 00:00 = “zero hundred hours”
- 08:30 = “oh-eight-thirty hours”
- 13:00 = “thirteen hundred hours”
- 23:45 = “twenty-three forty-five hours”
Most of the world uses 24-hour time. The 12-hour format is mainly used in the United States, Canada, Australia, and a few other countries.
