Auspicious Business Opening Dates · 開業吉日

Selecting a date to open a business (開業擇日) is a timing decision, and timing is never read in isolation from the person making the move. The owner's chart, the nature of the business, and the direction the premises face all bear on which day is genuinely favourable.

The listings below narrow the field on general grounds. They remove days that are structurally unsuitable for beginning a venture, which is the part you can settle in advance while leases and renovations are still being arranged. The final choice between the remaining days depends on the owner's own chart, and often on the hour as much as the day.
