The history of Arabic astrology and its influence on Japan’s “Saturday” history, as well as the profound and wide-ranging impact of Japan’s “Saturday” history, are discussed in detail below:

1、 The Origin and Development of Liuyao
Origin:
Liuyao, also known as Kongming Liuyao Star or Xiaoliuren, is a type of annotation in the traditional Chinese calendar used to indicate daily auspiciousness and misfortune.
There is a saying that the Six Yao Star originated during the Three Kingdoms period and was created by Zhuge Liang. It is called the “Kongming Six Yao Star” and is mainly used for military strategy. But this statement is still inconclusive.
Another theory suggests that Liuyao was created by Li Chunfeng during the Tang Dynasty, originating from his “Six Ren Inheriting Technique”.
development:
In the earliest version of Liuyao, it was divided into six types: “Da’an”, “Liulian”, “Suxi”, “Chikou”, “Xiaoji”, and “Kongshen”.
Later, in oral tradition, it became “Da’an”, “Youyin”, “Xiansheng”, “Akaguchi”, “Xianfeng”, “Fomei”, and was deliberately changed in order, forming the current popular version in Japan.
During the late Kamakura period to the Muromachi period in the 14th century AD, the sixth day of the lunar calendar was introduced to Japan. Subsequently, its name, order, and even meaning changed.
2、 The Application and Influence of Liuyao in Japan
Application:
Liuyao is widely used in daily life in Japan as a reference for coronation ceremonies, weddings, funerals, and rituals. The wedding ceremony usually chooses the day of “Da An”, while the funeral will avoid “You Yin”.
Liuyao is also used as an indicator for divination of daily good and bad luck, similar to the old imperial calendar in China. People will arrange their daily activities based on the prediction of the sixth day of the lunar calendar, avoiding important affairs on bad days.
influence:
Liuyao has had a profound impact on Japanese culture and has become an important component of Japanese folk beliefs and customs.
In Japan, Saturdays are usually marked in calendars and notebooks (a type of portable diary) for people to check at any time.
Liuyao is also used in the betting lottery of state-owned gambling institutions as a reference for predicting good or bad luck.
3、 The calculation method and specific meaning of Liuyao
Calculation method:
The calculation method of Liuyao is to add the month and date of a certain day in the old calendar. If they can be divided by 6, it is called “Da’an”, and if the remainder of 6 is 1, it is called “Chikou”, and so on. A leap month is the same as the previous month.
Specific meaning:
First win: heralds a good day of “taking action as early as possible”, with good luck in the morning and bad luck in the afternoon. Suitable for holding weddings and other auspicious events, but not suitable for holding funerals.
Friend quote: Japanese culture believes that holding a funeral on this day will also take friends to the Western Paradise, so funerals mostly avoid this day. Morning and evening are auspicious except for noon.
First loss: Contrary to first win, it is unlucky in the morning and lucky in the afternoon. It’s best to spend this day calmly.
Buddha’s extinction: It is the day when things come to an end. Although it may seem like a bad day, it is a good day for doing things or separating from someone who wants to break up. However, it is best to avoid celebrating on this day.
Da’an: It is a auspicious day for weddings, opening ceremonies, opening ceremonies, and various celebratory events on the sixth day of the lunar calendar.
Akaguchi: Considered a day of misfortune, doing nothing is good, only a brief noon is considered auspicious. Pay special attention to dangerous items such as knives and fire.
In summary, Japan’s “Saturday Festival” has a profound historical background and extensive social influence. It not only provides people with reference and guidance for daily activities, but also becomes an important component of Japanese folk beliefs and customs. Although modern science is skeptical of the predicted results of Saturday’s moon, its status and influence in Japanese culture cannot be ignored.
