Reading this star map
This Room diagram contains five stars. Two near the upper end can merge visually at small sizes. The red ring is on a lower star in the vertical arrangement, with another star still below it. Look closely at the upper pair to count all five.
Understanding the deity title
The traditional title 房日兔 (Fang Ri Tu) combines the mansion character 房, the association 日, and the animal image 兔. The astronomical entry is Room Mansion. A deity portrait expresses cultural imagery; a star map records positions and connecting lines. They can be read together without expecting the star pattern to resemble the animal.
What does this calculator result mean?
If a birthday lookup returns this mansion, the entered date is assigned to it by our daily almanac rules. It does not mean everyone born that day shares a personality, or that the Moon was inside this star pattern. Compare calendar, date and assignment system before comparing tools.

The historical text describes the roles of celestial asterisms. The life and personality associations below are our modern interpretations, not historical claims about people born on a particular date.
「爲明堂，天子布政之宮也」《晉書》卷十一・天文志上・二十八舍Fang is linked with the hall where government is conducted. A modern analogy is turning a shared intention into roles, dates and next steps. Organization makes cooperation possible, but assigning work need not mean absorbing everyone else's unfinished tasks.
