Lucky days to open a business or shop, 2026
For opening a business or shop, people often choose Taian, Tenshabi, Ichiryū-manbai-bi or Kinoe-ne, the day of beginnings. If construction or fitting-out work is involved, Sanrinbō, the unlucky day for building, is usually avoided too.
Dec 15 (Ichiryū-manbai-bi, Taian)Dec 27 (Ichiryū-manbai-bi, Taian)
On weekends and holidays (from now on): Dec 27 (Sun)
How we chose: days that are Taian or Tenshabi or Ichiryū-manbai-bi or Kinoe-ne day, excluding Fujōju-bi and Jushi-bi and Butsumetsu and Shakkō days. ◎ marks Tenshabi, or Ichiryū-manbai-bi that falls on Taian. ○ marks the other days. Saturdays and Sundays are marked in the tables; holidays are named under the date.
Tenshabi left out: May 20 (Fujōju-bi), Jul 19 (Jushi-bi, Fujōju-bi), Oct 1 (Butsumetsu), Dec 16 (Shakkō). We follow the view that Jushi-bi and Fujōju-bi cancel out a lucky day. Days left out only because of the rokuyō are fine if you don’t mind the rokuyō.

Tips for choosing a date
A company's date of incorporation is the day the registration is filed, so pick a lucky day among the weekdays when the Legal Affairs Bureau is open.
Lucky days in the almanac have long been used as a guide for choosing dates. Put your family’s plans and other people’s schedules first, and use them when you can’t decide. Almanac notes can differ between traditions.
