FAQ
Where do the almanac’s “suitable” and “avoid” entries come from?
They are looked up in traditional almanac tables from the day’s stem-branch, day officer, day spirit and lunar mansion. They are not a judgement about any person, and schools differ on individual terms; this page uses the common almanac convention.
Why does Japan’s calendar sometimes differ by a day from the Chinese lunar calendar?
Japan’s old calendar starts each month on the day of the new moon in Tokyo time, China’s lunar calendar in Beijing time. When the new moon falls between 23:00 and midnight in Beijing, it is already the next day in Tokyo, so the Japanese month starts a day later and the rokuyo shift with it.
What are Tenshanichi and Ichiryumanbai-bi?
Tenshanichi falls on the Wu-Yin day in spring, Jia-Wu in summer, Wu-Shen in autumn and Jia-Zi in winter, and is treated as the most auspicious day of the season to begin something new. Ichiryumanbai-bi is set by the solar month and the day branch and means one grain becoming ten thousand. Both are Japanese folk day-selection customs without a scientific basis.
The dos and don’ts are entries from traditional almanacs. They are folk reference only, guarantee nothing and are not medical, legal or investment advice.
Sources: almanac entries come from the lunar-javascript library (solar-term days by Beijing date); the Japanese old calendar fixes new moons in Tokyo time, and the Japanese day officer, solar month and lucky days use solar-term days by Tokyo date, checked against the National Astronomical Observatory of Japan; lucky-day rules are described on the page.
