Why is Jiazi 60 years old?

Yi Jia Zi is the ancient chronology of China. As early as 2697 BC, when the Yellow Emperor, the ancestor of China, founded the country, he was ordered to explore the qi of heaven and earth and the five elements (water, fire and earth in Jin Mu), and launched A, B, C, D, E, Ji, Geng, Xin, Ren, Gui, and Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei and Shen. Ten heavenly stems and twelve earthly branches are matched in turn, and sixty combinations from Jiazi to Guihai and * * * are called Sixty Jiazi. So a nail is 60 years.

Yi Jia Zi is the ancient chronology of China.

Heavenly Stems and Earthly Branches

Heavenly stems and earthly branches, referred to as Ganzhi for short, is used to arrange year numbers and dates in the summer calendar. Ten days of dryness

Ten heavenly stems: A, B, C, D, E, Ji, G, Xin, Ren, Gui, * * *;

Twelve earthly branches

Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai are collectively called the Twelve Earthly Branches.

Yin and Yang Division of Trunk and Branch

Branches are still divided into yin and yang: A, C, E, G, Ren for yang dryness, B, D, Ji, Xin, classified as yin dryness; Zi, Yin, Chen, Wu, Shen and Xu are the Yang branches, while Ugliness, Mao, Si, Wei, You and Hai are the Yin branches.

Heavenly stems and earthly branches collocation arrangement. The heavenly stems are in front, the earthy branches are behind, the heavenly stems start from A, the earthy branches start from Zi, the yang stems are matched with the yang branches, and the yin stems are matched with the yin branches (the yang stems are not matched with the yin branches, and the yin stems are not matched with the yang branches). * * There are sixty combinations, which are called sixty jiazi. In the past, people in China used to recycle calendar year, calendar month, calendar day and calendar time.

For example, China's 60th birthday is the first birthday.

Sixty nail cycle

Sixty jiazi

Ten heavenly stems and twelve earthly branches are combined circularly: Jiazi, Emei and Bingyin ... Until Guihai, * * * gets sixty combinations, which are called Sixty Jiazi, and so on, endlessly. Year, month and day are all 60 cycles. 60 is a wonderful number in the field of time. Not only did the ancients in China take 60 as the cycle, but now in the western timing method, one minute is 60 seconds and one hour is 60 minutes. Similarly, the current 24-hour day corresponds to the traditional 65,438+02 hours in China (one hour is a big hour and two hours is a big hour). China takes five days as a big cycle of one hour, so-called five-day waiting, * * is 60 hours. The following are sixty kinds of stem and branch combinations (called sixties):

Jia Zi, Yi Ugly, Bing Yin, Ding Mao, Chen Wu, Keith, Geng Wu, Xin Wei, Ren Shen, Gui You,

JOE, Yihai, Bingzi, Ding Chou, Wuyin, Jimao, Chen Geng, Xinsi, Renwu, Guiwei,

Shen Jia, Yi You, Bing Xu, Ding Hai, Woods, Ji Chou, Geng Yin, Xin Mao, Ren Chen, Gui Si,

Wu Jia, Yiwei, Shen Bing, Ding You, Wuxu, Jihai, Gengzi, Xin Chou, Ren Yin, Gui Mao,

Chen Jia, Yi Si, Wu Bing, Ding Wei, Wu Shen, Ji You, Geng Xu, Xinhai, Renzi, Gui Chou,

Jia Yin, Yi Mao, Chen Bing, Ding Si, Wu Wu, Wiki, Geng Shen, Xin You, Ren Xu, Gui Hai.

annual report

The chronology takes sixty years as a cycle in turn. For example, 19 1 1 was the year of Xinhai, and the Revolution of 1911 broke out. In the official calendar year, the new year begins on the first day of the first month (23:00, 23:000 1:00), but in some numerology viewpoints (official calendar), the new year begins in the beginning of spring and has nothing to do with the folk lunar calendar.

Yue Ji

In ancient China, sixty Jiazi calendars were not commonly used, which had little influence. Usually, the calendar month begins on the first day of the first lunar month, and the branch of leap month is the same as last month. For example, the branch of leap month is JOE in September, and the branch of leap month is still JOE before October. In the trunk calendar, trunk and branch are converted into the delivery time of solar terms, for example, Mitsuki is in front of mango seeds and noon is behind mango seeds.

Iri

This is the earliest usage of stems and branches, and a day and night is a day. Mark the days with sixty jiazi in turn. For example, today is Jiazi Day, and tomorrow is night feud, with a cycle of 60 days. Zizheng (00:00) starts a new day. The earliest recorded date in China is February in the Spring and Autumn Period of Lu Yingong (720 BC), which is more than 2,700 years ago. This is the longest date on record in the world.

Gich

Every day is divided into 12 equal parts, that is, 12 hours. 5 days ***60 hours, represented by 60 Jiazi. For example, the present hour is Bing Yin, and the next hour is Ding Mao. The establishment of time requires the calculation of solar time to record the movement and rotation of the earth around the sun.
