An hour is two hours.
In ancient China, when formulating the calendar, it was formulated with reference to the movement of the moon. Of course, not exactly, because to divide spring, summer, autumn and winter, this is actually related to the movement of the sun, and it is said that it is related to the rotation of the earth around the sun. But in general, the number of days in each month is determined by the law of the moon's movement, and the error is adjusted by leap months.
Referring to the movement of the moon, the lunar calendar spends less time per month on average than the solar calendar. The lunar calendar generally has 30 days in the big month and 29 days in the small month. A month is basically one day less than the solar calendar. In three years, it is about 30 days less. So our leap month is an additional month, and the leap month of the solar calendar is an additional day.
But the time of each day is the same as that of each day of the solar calendar. The lunar calendar divides the day into 12 equal hours, and the solar calendar divides the day into 24 hours, so that one hour is equal to two hours, which is 120 minutes.
Each hour is divided into eight quarters, each of which is 15 minutes. In general, the smallest unit of measurement of time in ancient China was the moment.
In ancient times, the twelve earthly branches were used to represent the 12 hours, which were Zichou Yin Mao Chen, Siwu Wu Wei Shen Youxuhai. How to convert between the specific hour and 24 hours is not much profound knowledge. The correspondence between the two is:
It is 11 p.m. to 1 a.m.;
It's 1 a.m. to 3 a.m.;
It was 3 a.m. to 5 a.m.;
It is 5 a.m. to 7 a.m.;
The hour is from 7 a.m. to 9 a.m.;
It is from 9 a.m. to 11 noon;
Noon is from 11 noon to 1 noon, and at 3 o'clock in the afternoon, it is 11:45 p.m.;
It is from 1 p.m. to 3 p.m.;
The time is from 3 p.m. to 5 p.m.;
The unitary time is from 5 p.m. to 7 p.m.;
7 p.m. to 9 p.m.;
It's 9 p.m. to 11 a.m.
Among the above corresponding figures, the first numbers include this time period, and the following numbers do not include this time period.
A day passes, a day repeats, days and days, months and months, and time passes like this. So the twelve hours came again and again. The twelve hours begin at the hour of the child and end at the hour of the hour. But there is a knowledge point involved that rarely attracts people's attention, that is, the sub-hour corresponds to 11 a.m. to 1 a.m., that is, the Chinese start their new day at 11 p.m. According to the solar calendar, it starts at 12 o'clock.
The time points of many traditional festivals in China are set on the basis of the lunar calendar, so when celebrating traditional festivals, when it comes to time, we should use the 12 hours as a reference, rather than the 24-hour system. So the time of the Chinese is an hour earlier than that of the world.
Therefore, the firecrackers should be set off on the night of the Chinese New Year's Eve to welcome the old and welcome the new, and they should be set off at 11 o'clock, not 12 o'clock. **When the countdown to the New Year, the TV Spring Festival Gala also starts the countdown when it is close to 11 o'clock, not when it is close to 12 o'clock.
