What year is the second year?

The second year is an ugly year. Ebony is one of the main branches, and Ebony Year is the second year of a cycle in the long history of China.

Ebony is one of the main branches, and the order is the secondary branch. The former is Jia Zi and the latter is Bing Yin. On yin and yang and five elements, the essence of heavenly dryness belongs to the wood of yin, and the ugliness of earthly branches belongs to the soil of yin, which is a kind of wood soil.

The second year of a cycle in traditional calendar years in China is called "ugly year". In the following AD years, if the number of years is divided by more than 60, or the number of years is reduced by 3, the remainder divided by 10 is 2, and the remainder divided by 12 is 2. The years from beginning of spring to beginning of spring the following year are all "Ugly Year".

In the China calendar, the time for the moon to orbit the earth once (29.5306 days) is regarded as January, and the time for the earth to orbit the sun once (365.438+09 days) is regarded as a year. In order to make the average number of days in a year consistent with the number of days in the tropical year, a leap month is set up. According to records, in the 6th century BC, China began to coordinate the lunar calendar with the solar calendar by the method of 19.

Heavenly stems and earthly branches is a symbol designed by the ancients to facilitate the 60-digit system when building calendars. For ancient China people, the existence of heavenly stems and earthly branches was as simple as Arabic numerals. Later, these symbols were applied to maps, directions and time (time axis and space axis), so these numbers were endowed with more and more meanings.

The ancients (Yellow Emperor) observed Wang Shuo's moon and found that the two moons were about 59 days. 1February is generally more than 354 days (similar to the length of a tropical year), so the ancients got the concept of 12 months in a year. Then came the combined calendar of yin and yang, but this is different from the solar calendar.
