Shakko 赤口
shak-kō — "red mouth"
Lucky at noon only
An inauspicious day inherited from onmyodo divination. Only the hour of the horse — roughly 11am to 1pm — is safe; the rest of the day is not. Because "red" suggests fire and blood, tradition advises care with blades and flames, and avoiding celebrations.
