In general, there are two ways to represent time in modern international terms. A 24-hour clock, usually in 24-hour units, that starts at 0:00 a.m. and ends at 0:00 a.m. the next day. A 12-hour clock, usually measured in 12-hour units, that starts at 12 a.m. and ends at 12 noon, and then continues from 1 p.m. to 12 p.m.
In the 24-hour format, the day is divided into 24 hours, and each hour is represented by two digits, such as 00 to 23. Among them, 00:00 is 0:00 in the morning, which is also the beginning of the day;12 p.m. is the end of the day and of course the beginning of the next day.
Usually our traditional wall clocks and watches keep track of the time according to the 12-hour clock, but there are also special 24-hour items. If necessary, we can choose the goods according to our preferences. The timing method in the electronic mobile phone computer can be switched and adjusted, and you can set it yourself according to your own Xi.
So, how do you count 24 hours?It's actually very simple, for example, the current time is 8 o'clock in the evening, which is 20 o'clock, and by 8 o'clock in the evening the next day, 20 o'clock in the 24-hour system is 24 hours. and so on at other time points. However, 1 minute equals 60 seconds, and 1 hour equals 60 minutes, the decimal system does not change like the 12-hour system.
