Rokuyō (days of the week)




The rokuyō (六曜) are a series of six days that predict whether there will be good or bad fortune during that day. The rokuyō are still commonly found on Japanese calendars today, and are often used to plan weddings and funerals. The rokuyō are also known as the rokki (六輝). In order, they are:
先勝 (senshō) - Good luck before noon, bad luck after noon
友引 (tomobiki) - Bad things will happen to your friends. Funerals avoided on this day.
先負 (senbu) - Bad luck before noon, good luck after noon
仏滅 (butsumetsu) - Most unlucky day. Weddings best avoided.
大安 (taian) - Most lucky day. Good day for weddings.
赤口 (shakkō) - The hour of the horse (11 am - 1 pm) is lucky. The rest is bad luck.
