12:00 in 12-Hour Time
12:00 is 12:00 PM.
Written 1200 in military time and said “twelve hundred hours”. Going the other way, 12:00 PM is 12:00.
The 12:00 hour is noon, and the other hour people get wrong: 12:00 is 12 PM, and there is no such thing as 00:00 midday.

Said aloud: “twelve hundred hours” on the 24-hour clock, “twelve noon” on the 12-hour one.
Why 12:00 converts the way it does
Noon is the second of the two times people get wrong. 12:00 on the 24-hour clock is 12:00 PM — it keeps its twelve, and it is PM, not AM. Only midnight moves, to 00:00. If you remember one thing about converting: 12 stays 12 at noon and becomes 0 at midnight.
The minutes are the same on both clocks — a whole hour stays a whole hour — and 12:00 is in the afternoon, which is the information the AM/PM label is carrying.
Need this time to actually do something? Set an alarm for 12:00 PM, or use the timer to count a length of time instead of waiting for a clock time.
