The six days
There are six: Sensho, Tomobiki, Senbu, Butsumetsu, Taian and Shakko. Because the cycle is set by the lunar date, the order jumps at every new moon.

Rokuyo is a six-day cycle of fortune printed on almost every Japanese calendar. The day is found by adding the lunar month to the lunar day and taking the remainder after dividing by six. It arrived from China and spread through Japanese calendars in the late Edo period. Because the count restarts on the first day of each lunar month, the sequence skips a step whenever a new moon falls — which is why rokuyo cannot be worked out from the Gregorian date alone.
