Hours Between Two Dates

An hour is most normally defined as a flow of fourth dimension equal to sixty minutes, where a minute is equal to 60 seconds, and a second has a rigorous scientific definition. There are as well 24 hours in a day. Near people read time using either a 12-hour clock or a 24-hour clock.

12-hour clock:

A 12-60 minutes clock uses the numbers ane-12. Depending on the clock being used, most analog clocks or watches may not include an indication of whether the fourth dimension is in the morn or evening. On digital clocks and watches, "AM" stands for ante meridiem, meaning "earlier midday," while "PM" stands for mail meridiem, or "later on noon." By convention, 12 AM denotes midnight, while 12 PM denotes noon. Using the terms "12 midnight" and "12 noon" can remove ambiguity in cases where a person may not be accustomed to conventions.

24-hour clock:

A 24-hour clock typically uses the numbers 0-23, where 00:00 indicates midnight, and a day runs from midnight to midnight over the course of 24 hours. This fourth dimension format is an international standard, and is ofttimes used to avert the ambiguity resulting from the use of a 12-hour clock. The hours from 0-11 announce what would be the AM hours on a 12-hr clock, while hours 12-23 denote the PM hours of a 12-hour clock. In certain countries, 24-hour time is referred to as military time, since this is the time format used by militaries (and other entities) around the world, where unambiguous time measurement is particularly of import.
