Days that overlap with other lucky days
Mar 5 (Tiger day + Tenshabi + Ichiryū-manbai-bi) – also Sanrinbō, so not for building (some regions avoid moving too), Mar 17 (Tiger day + Ichiryū-manbai-bi) – also Sanrinbō, so not for building (some regions avoid moving too)
Days that fall on Fujōju-bi or Jushi-bi are left out. When Tenshabi and Fujōju-bi coincide, some schools say Tenshabi cancels the bad luck and others give Fujōju-bi priority.
How to use Taian
Taian is lucky all day, and is widely used for weddings, registering a marriage, moving, collecting a new car and signing contracts. The rokuyō are a relatively recent addition to the calendar with little basis, but many people still care about them for celebrations.
The meaning of these days is explained in Lucky days and festivals of the eto, and the calculation in How the calendar is calculated. Almanac notes can differ between traditions.
