    1. Analog Clock or the 12-hour clock

    We measure and define what time of the day it is using clocks. A clock in general has 12 numbers written on it, from 1 to 12. It has an hour hand and a minute hand. Some clocks have a third hand as well. It shows time in seconds and is the fastest-moving hand. The time is usually based on a 12-hour clock. The hour hand, the shorter of the two hands, completes 1 rotation (360°) in 12 hours in a normal 12-hour analog. The minute hand, the longer hand, completes 1 rotation through 360° in 60 min...

    2. Digital Clock or the 24-hour clock

    Generally, we use the 12-hour clock to measure time. But railways, airlines, armed forces, and newspapers use the 24-hour clock. On the 24-hour clock, the hours from midnight to the next midnight are marked 0 to 24. 1. On a 24-hour clock, we use 4 digits. 2. The two digits on the right show the minutes past an hour. 3. The two digits on the left show the number of hours. For example: 12:45 means it is 45 minutes past 12 hours 18:20 means it is 20 minutes past 18 hours A day starts at midnight...
