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.
Detailed explanation. To convert from AM (12-hour clock) to 24-hour clock, when the hour is 12 (first hour after midnight), you should change the 12 by 0 then remove the 'AM' to get the time in 24-hour time. So, 12:30 AM equals 0:30 in 24-hour time.
Time Span Calculator. This online calculator computes how much time is passed between two time points, specified in hours and minutes. But, unlike others, it computes several values - including time span over midnight. For example, for these two time-points: 10:00 AM and 8:00 PM, it will calculate:
The 24-Hour Clock is a Time format where you don’t use AM and PM. Counting for the first 12 hours of the day is the same as in 12-Hour Clock but then hours counting continue from 13 to 24 for PM hours. 24-Hours Time format is also known as Military Time.
PM = Post meridiem: After noon. Using numbers from 1 to 12, followed by am or pm, the 12-hour clock system identifies all 24 hours of the day. For example, 5 am is early in the morning, and 5 pm is late in the afternoon; 1 am is one hour after midnight, while 11 pm is one hour before midnight.
