[By the way, what are Rokuyo?]
Rokuyo (六曜) refers to the six days of the week in the traditional Japanese calendar that indicate good or bad luck for each day. Specifically, there are six days: "Sensho", "Toyobiki", "Senbu", "Shakko", "Taian", and "Butsumetsu". Each day has a meaning that is said to be suitable for certain actions and events.
Sensho (先勝)
On this day, the morning is considered auspicious. It is recommended to act quickly to start something, and it is especially suitable for business negotiations and starting new projects. However, you should be careful as your luck will decrease from the afternoon onwards.
Tomobiki (友引)
This day is said to attract friends, and is ideal for celebrations such as weddings. It is also a good day for gatherings and events with friends. However, it is said to be avoided for funerals.
Senbu (先負)
It is auspicious from the afternoon onwards, and it is recommended to act carefully, especially in the morning. When making business or new plans, it is better to move your actions after the afternoon.
Shakko (赤口)
This is a day when you need to be especially careful, and it is important to be careful of fire. It is also said that it is better to avoid important decisions and contracts. It is recommended to spend this day calmly, as you may be short-tempered or get into trouble.
Taian (大安)
This is considered the most auspicious day, and it is said that you are likely to succeed in whatever you do. This is a great day for weddings and starting new businesses. It is also a good day to make special plans with friends and family.
Butsumetsu (仏滅)
This is considered the most unlucky day, and anything important should be avoided. It is best to avoid starting anything new on this day, and spend your time relaxing.
[Summary]
Incorporating Rokuyo into your daily life may help you make better decisions. Planning important events on Taian days and spending modestly on Butsumetsu days will give you a sense of security in terms of your mood and feelings.
Also, making plans to spend time with friends on Tomobiki days can be an opportunity to deepen your relationships. This type of use is a new approach to utilizing the wisdom of Rokuyo.
