Nine Star Ki | Your two stars as a pair

From two dates of birth,
see how your stars pair up

We find both people's birth stars and look up which way the stars face each other in the Nine Star generating-and-overcoming table of Sonoda Shinjirō's Kaisei Hōi Meikan.

Before you start
In Sonoda Shinjirō's three original books, we found no passage about compatibility between people. In the original, the table used here is a table for finding lucky and unlucky directions. Applying it to two people's stars is this site's choice. This site's choice

The calculation runs only on this device. The two dates of birth are not sent anywhere or put in the web address. They disappear when you close this tab.

The pairing of your stars, the reasons and the text of the original are free. The pairing of your birth-month stars and the detailed chapter on getting along are for members, at ¥480/month (tax included).
