Do foreigners have lunar calendar?

China, South Korea, North Korea and Vietnam, the radiation areas of Chinese civilization, also have lunar calendar ... First, the advantages of the current Gregorian calendar (Gregorian calendar):

First, the Gregorian calendar is officially used by most countries in the world and is universal;

Secondly, Gregorian calendar belongs to the flat calendar defined by flat time period, so its algorithm is simple, the number of days is basically fixed, and leap rules are set;

Third, calendar years and calendar days are well coordinated, only 365 days and 366 days;

Fourth, the calendar day basically corresponds to the height of the sun (direct angle), and the error is only 1 to about 2 days.

Second, the shortcomings of the current Gregorian calendar:

First, the first year of A.D. is in the middle of human history, so it is not convenient to calculate the early period of human history;

Second, there was no strong astronomical significance at the beginning of the year;

Thirdly, there are four calendar days: 28th, 29th, 30th and 3 1 day, which are arranged irregularly.

Fourth, it has strong religious significance and the brand left by Roman imperial power, which is not conducive to the exchange of different cultures and nationalities;

Fifth, leap days in 400 years are not as simple and accurate as those in 128 and 3 1.

6. Although there is the sun, there is no moon content, and its date cannot reflect the moon phase. It is a solar calendar, which is not conducive to the protection of the world's moon culture, nor to the acceptance and recognition of the masses in these countries;

Seventh, because the length of the calendar month has no obvious astronomical significance, human factors are very strong and can even be changed at will;

Because it is a flat calendar, its calendar day cannot correspond to its corresponding astronomical phenomena-the height of the sun.

Third, the advantages of the current lunar calendar:

First, the lunar calendar is a fixed calendar, with the characteristics of astronomical calendar, which can well correspond to various astronomical phenomena, such as its solar terms strictly correspond to the height of the sun, calendar days strictly correspond to the phase of the moon, the frequency of the absence and appearance of leap months corresponds to the perihelion and distant sun of the earth, and other astronomical phenomena, such as sunrise, sunset, five-star orientation, solar eclipse, tides and so on. Even calendar months roughly correspond to the height of the sun;

Second, the number of days in the lunar calendar is only 29 and 30, and it is stipulated by a fixed date. There are very few human factors and it is not easy to change it at will.

Third, the beginning of a year has a strong astronomical significance, with the astronomical significance of the year of the sun and the moon;

Fourth, the combination of the lunar calendar and the solar calendar can best reflect the traditional culture of the Chinese nation's unity of man and nature;

Fifth, recycle the chronology of trunk and branch and the chronology of zodiac; Because it contains solar terms, it is very beneficial to the division of the four seasons, and because it contains the moon phase, it also reflects the influence of tides, eclipses and other celestial phenomena and the moon on the climate. At the same time, it also includes twelve calendars (similar to Shen Kuo's Twelve Qi Calendars, which is more accurate than it) and a special solar calendar for the 72nd period. It is a dual-track calendar, which facilitates the exchange of different cultures and nationalities.

Sixth, because it is the most thorough astronomical calendar, other calendars should be compared with it, which is conducive to protecting traditional culture.

Fourth, the shortcomings of the lunar calendar:

First, because the lunar calendar is a fixed calendar, and the calendar month uses a fixed new moon, the number of days in the same calendar month is uncertain every year, so it is not convenient to count the number of days;

Second, the length of the calendar year is 353 days, 354 days, 355 days, 383 days, 384 days and 385 days, which is not conducive to statistical aging;

Third, the period of trunk and branch is too short, which is not convenient for long-term distinction and memory;

Fourth, the leap is opaque and the leap month is uncertain;

Fifth, some of them are superstitious, but after the founding of New China, they have been eliminated. With the popularization of science, fewer and fewer people believe in them; As for some folk sacrificial activities, they are already folk customs. Not superstition.

The advantages and disadvantages of the above-mentioned Gregorian calendar are mainly reflected in the differences between Chinese and western cultures. Gregorian calendar is a flat solar calendar, and lunar calendar is a comprehensive calendar with a fixed day and a fixed yin and yang calendar.

Therefore, it is meaningful to combine the two calendars, so as to integrate the advantages of the two calendars and avoid their disadvantages.

Regrettably, for a long time, some celebrities did not understand the characteristics of the dual-track system of the lunar calendar. But the powerful civilizations in western Europe are biased against the lunar calendar. Emphasizing the western calendar instead of the China calendar (including the calendars of other ethnic minorities in China) and the solar calendar instead of the lunar calendar is very unfavorable to the inheritance of the 5,000-year astronomical calendar culture in China. As a result, the lunar calendar was not written into the teaching plan of primary and secondary schools, and finally this excellent astronomical calendar was completely forgotten by the next generation. This is pathetic.

Lunar calendar is one of the few astronomical calendars in the world today, and it is a dual-track system of yin and yang or even a multi-track system (such as the reflection of five-star orbital periods such as Venus period). It is the only calendar in the world that uses the most advanced astronomical data and theories, and it is the most thorough calendar. I hope the people of China will pass on this calendar.

Therefore, we should treat the lunar calendar fairly and integrally with the oriental way of thinking.
