how the six days of the week are determined
結婚式は大安がいいとか、お葬式は友引はダメとか、世間の人はいろいろ言います。建築業界にも、この日はよし、この日はダメ、というのがあります。お客様の中には、暦など全く気にされない方もいらっしゃいます。しかし知っておいた上で日程調整ができればありがたい、という方もいらっしゃいます。今回は六曜について学んでいきます。「今日はお日柄も良く～」(English) People say all sorts of things, such as 'Taian' is suitable for weddings and 'Tomohiki' is not good for funerals. In the construction industry, too, certain days are excellent, and certain days are evil. Some customers do not care about the calendar at all. Others, however, would appreciate knowing the date and being able to arrange the date. In this article, we will learn about the six days of the week. 'Today is a good day for you...'
Do you know how the six days of the week are determined?
1)
When some people decide the memorial day, they are concerned about the six days of the week (六曜, Rokuyou).
So, do you know how the six days of the week are decided on the calendar?
2)
Please look at the Japanese calendar, which marks the six days of the week.
You will see that there is a particular order of sequence.
3)
The order is Sensyo, Tomobiki, Senbu, Butsumetsu, Taian, Syakku, Sensyo.
先勝、友引、先負、仏滅、大安、赤口
However, if you follow the order of the days all the way through, you will find places where the order shifts.
4)
The order shifts in one place and returns to the regular order again.
The shift occurs about once a month.
This shift makes the six days of the week seem mysterious.
5)
The six days of the week are determined in correspondence with the lunar calendar.
The way it is determined is as follows:
6)
The first day of the first month of the lunar calendar and the first day of the seventh month of the lunar calendar are the first days of the year.
The above-determined order then starts from there.
7)
The first day of the second lunar month and the first day of the eighth lunar month is Tomobiki.
The first day of the third lunar month and the first day of the ninth is Senbu.
The first day of the fourth lunar month and the first day of the tenth lunar month is Butsumetsu.
The first day of the fifth and eleventh lunar month is Taian.
The first day of the sixth and twelfth lunar month is Syakkou.
8)
From the second day of each, they proceed in a fixed order.
Very simple. Same every year.
A simple law determines it.
9)
However, there is no indication of the dates of the lunar calendar in the current calendar, so inexplicably, the order of the six days of the week jumps, which makes more people grateful to feel something.
If you look carefully at a calendar that also shows the days of the lunar calendar, you will see that the order of the six days of the week jumps when the lunar calendar month changes.
10)
Many people may choose a good day to celebrate their son or daughter's Shichi-Go-San celebration and decide on the date of the festival.
In the lunar calendar, the fifteenth day of the eleventh month is always the first day of the eleventh lunar month.
*Shichi-go-san festival is an annual Japanese festival celebrating children's growth. It takes place on or around November 15.
11)
The first day of the first month of the lunar calendar (Tsuitachi
) is always 'Taian.'
Therefore, if you count them in order, the fifteenth day of the eleventh month is "Sensyo."
In the lunar calendar, the fifteenth day of the eleventh month is never "Taian" or "Tomobiki."
12)
Incidentally, 15 January of the lunar calendar, the day on which the samurai family held the Genpuku-no-gi ceremony, is also 'Senbu.'
Our ancestors did not decide the dates of age rituals according to the six days of the week.
13)
It is not only age rituals. Look at the festival's days.
The first victory is the seventh day of the first lunar month, and 'Jinjitsu' is Sensyo - the first lunar month.
3 March 'Peach Festival' is 'Taian.'
5 May 'Shobu Festival' is 'Senbu.'
7 July 'Tanabata, Festival of the Weaver' is 'Senyo'.
9 September 'Tyo-yo, chrysanthemum Festival' is 'Taian.'
*The old custom called Nanakusa-gayu spread all over Japan in Edo era. On the morning of January 7th (the day called Jinjitsu no Sekku: one of the five seasonal festivals, which means person-day festival), people have salt taste rice porridge made by "spring seven wild herbs."
14)
Next, calendar festivals.
The 15th night is 'Butumetsu.'
Thirteen Nights is 'Senbu.'
You can see that the meaning of the day itself took precedence.
15) 大安
The six days of the week are generally known as the following days.
Taian - a Day of Great Peace
Good luck with all ceremonies.
Wedding and (ceremonial) betrothal of Good luck in all matters and a good time to be proactive.
The best day for the so-called Taian auspicious day is known to everyone.
16) 赤口
Syakou- a red mouth
A peaceful day, especially around noon.
Only noon is a good day for action. Morning and evening activities should be avoided.
Although noon is considered a good day, it is interpreted as the hour of noon (11 am to 1 am), not the instantaneous time, and is neither good nor bad, neither liked nor disliked.
This day is considered a good day around noon.
17) 先勝
Sensyou - a first victory
It is an excellent day to start in the morning, rather than a bad day in the afternoon.
It is a good day to act in the morning, and it is not a good day to work in the afternoon. It is an excellent day to take action in the morning, which is good.
It is good to hurry on this day.
18) 友引
Tomobiki - to attract friends
The second-best day after Taian.
The morning and evening are promising, so refrain from competitive events, funerals, etc. Noon is terrible luck.
The name "Yu-in" is derived from the Japanese words for speed and swiftness.
So this is a perfect day for good things to attract friends.
This day is considered as suitable for weddings as Taian. Especially in the evening, it is said to be auspicious.
19) 先負
Senbu - a first loss.
Suitable for quiet affairs, good for everything from the afternoon.
Avoid activities in the morning.
Conversely, it is a good day to act calmly in the afternoon.
This day is good for quiet matters such as weddings, especially in the afternoon, which is said to be good luck.
It is a good day for the small happy days and a good day if you avoid doing anything strenuous and keep a low profile.
It is a good day for quiet and solemn events such as weddings.
20) 仏滅
Butsumetsu - a bad luck
Not suitable for celebrations.
Do not take any action. If you fall ill, it will be prolonged.
This day has long been said to be bad for everything.
It is generally considered to be the anniversary of the death of Buddha (Shakyamuni), so celebrations should be avoided.
Still, those not related to Buddha (Nichiren, Shinto, Christian, non-religious) may hold weddings.
21)
The auspicious day for construction is Taian.
Next is Sensyo (good in the morning), Tomobiki (good except at noon), and Senbu(good in the afternoon).
The bad luck days Butsumetsu (Buddha's death) and Syakkou(red mouth) are usually avoided.
