Which year is sunny?

Years with even mantissa are positive years, such as 20 10, 20 14, etc. Years with odd mantissa are negative years, such as 20 1 1, 20 13, etc.

Ten-day stem: 1 A, 2 B, 3 C, 4 D, 5 E, 6 F, 7 G, 8 X, 9 N, 10 C is called "stem" for short. Singular numbers are masculine and even numbers are feminine. Specifically, methylprednisolone is positive, while ethyl butyl hexine is negative.

There are twelve earthly branches: 1, 2 ugly, 3 cloudy, 4 gross, 5 Chen, 6 Si, 7 noon, 8 Wei, 9 Shen, 10 You,1Xu, 12 Hai. (the ground branch is called "branch" for short. Singular numbers are masculine and even numbers are feminine. That is, zi, yin, Chen, noon, Shen and deficiency are yang; Ugly, ugly, awkward, unfinished, unitary, and the sea is cloudy).

Similarly, in the zodiac, rats, tigers, dragons, horses, monkeys and dogs belong to Yang; Cattle, rabbits, snakes, sheep, chickens and pigs belong to Yin; Moreover, the year is divided into yin and yang or the phase of yin and yang matches. In this way, there will be a sunny day and a cloudy day. For example, 20 12 year is the Year of the Loong (solar year), and 20 13 year is year of the snake (solar year).

Extended data:

1. Reasons for judging positive and negative years according to year mantissa:

The ancients used the words A, B, C, D, E, Ji, G, Xin, Ren, Gui, Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai to time, which is also called Sixty Jiazi.

The ancients combined the moon with the twelve laws into one. Twelve laws divide an octave into twelve semitones that are not completely equal. Such a legal system, then the odd laws are all yin laws, and the even laws are all yang laws. So a year with odd mantissa is cloudy.

2, sixty years a jia:

In the calendar year, it is divided into two parts first with heavenly stems and then with earthly branches, and is labeled with quantifiers such as year, month and day. Such as Jiazi Year and Ugly Year. Ten heavenly stems and twelve earthly branches can't match, so the ancients delayed this combination until the last word of heavenly stems matched the last word of earthly branches, and the year of Guihai ended.

This combination can be calculated and repeated five times, that is, 60 years, which is the origin of a nail for 60 years.
