About Rokuyō

As with other countries, Japan has a calendar with 7-day weeks. There is also a supplementary 6-day pattern, known as Rokuyō, which is superimposed on the calendar.

This page introduces the six Rokuyō days, each of which has a specific period of good luck and bad luck:

Day name	Morning	Noon	Afternoon
Senshō
Tomobiki
Sakimake
Butsumetsu
Taian
Shakku

You'll notice that Rokuyō maintains a balance of good and bad luck, reflecting the concept of Yin and Yang.
