1. Calendars used in the history of China include solar calendar, lunar calendar and yin-yang calendar. The "blind year" is the result of some "positive" arrangement of the lunar calendar.

2. Gregorian calendar, probably the earliest calendar used by our ancestors, is based on the law of the sun. The ancients thought that the sun went around the earth with a period of one year-today we know that it is the period of the earth going around the sun, but the ancients' understanding is the opposite. According to scholars' research, there was also a solar calendar in the Warring States period. There are ten months in a year, in the name of heavenly stems. The 36th day of each month is divided into ten days in the name of earthly branches.

3. In this way, 10 360 days a month, plus five or six days of "wasted time", a year is 365 days or 366 days. In this case, the arrangement of solar terms first includes "summer solstice" and "winter solstice", followed by "vernal equinox" and "autumn equinox". The tropical year is divided into two seasons: spring and autumn, and then into spring, summer, autumn and winter and even twenty-four solar terms. There are traces of this calendar in the ancient document Guanzi, which is related to the torch festival of Yi people and southwest ethnic minorities. The saying "Chinese New Year is celebrated from winter to Sunday" is still circulating among the people in Lingnan, which is the residual memory of this calendar. The ancients did regard the winter solstice of Yiyang Renewal as New Year's Day.

4. What day is on the calendar? Just name a day of the year and you can immediately calculate a day of the week.

Just calculate the day code, month code and year code. What day of the week is the remainder of three divided by seven (Wednesday if the remainder is three).

5. Day code calculation: The simplest day code is a number. Monthly code calculation: Monthly code is also very simple. The following numbers are 12: 1 4 7 2 5 7 3 6 1 4 6, which respectively represent the codes of1-1February. For example, the code for September is 6. According to the guest, he used the reverse method to calculate the code of 12 months, that is, he knew the day of the month and then calculated the month code in turn. )
