What is the difference between 12 hours and a 24-hour clock?

12-hour clock

AllCalculators.net The 12-hour clock divides the full day into two cycles and is used in many countries that prefer English as the main language. The counting of time has two periods:

• 12 hours from midnight, denoted 12:00 am to midnight
• Denoted 12:00 pm and from midnight to midnight, completing the 24-hour cycle.

The 12-hour clock is normal day and night, which consists of twelve hours characterized by the moon. Most analog clocks and watches have only a 12-hour clock. This clock includes night, morning, afternoon, and evening.

24-hour clock

In ancient Egypt, the 24-hour clock was used for centuries and continues to be used for years. The convention runs the day from midnight to midnight for twenty-four hours continuously. The time counting starts at midnight at 00:00 and runs through to twenty-three fifty-nine. Medics use this 24-hour clock to record patients' histories. Unlike the 12-hour clock, the 24-hour clock is specific to timelines and easy to interpret for most people.

How do you calculate hours and minutes worked?

• You can calculate hours and minutes worked daily by converting all times to the 24-hour format.
• Subtract the starting time from the end time. Example: start working at 8:30 and finish at 16:40; the result will be 16:40 -8:30 = 8:10
• You can also use the carry-over method. Example: subtract 8:25 from 16, and it looks like: 15:60 – 8:25 = 7:35
• Calculate weekly or monthly working time, and sum the times from all days.
