## What is time format

An hour is usually defined as a period of time equal to 60 minutes, where one minute is equal to 60 seconds. There are 24 hours in a day. Most people keep time using either a 12-hour clock or a 24-hour clock.

## 12-hour time format

The 12-hour clock uses the digits 1-12. Depending on the clock being used, most analog clocks or watches may not include an indication of whether the time is morning or evening. On digital clocks and watches, “AM” stands for ante meridiem, meaning “before noon,” while “PM” stands for post meridiem, or “after noon.” According to tradition, 12 o’clock at night means midnight, while 12 o’clock means noon.

## Time format 24-hour

The 24-hour clock typically uses the numbers 0-23, where 00:00 indicates midnight, and 12:00 indicates noon. And a day lasts from midnight to the next midnight over the course of 24 hours. This time format is an international standard, and is often used to avoid ambiguity arising from the use of the 12-hour clock. In a 12-hour clock, hours 0-11 indicate AM time, while hours 12-23 indicate PM time.
