BIRTHPRINT

One sky. Many stories.

A sky can carry more than one story. Birthprint keeps cultural traditions separate from calculated astronomy and from its own playful interpretations.

Chinese year cycle

Chinese calendrical traditions associate years with a repeating animal cycle and the ten heavenly stems. The lunar new year, rather than January 1, marks the change used here.

Your birthday, in other calendars

Civil-date conversion using ICU/CLDR: Chinese, Hebrew and tabular Islamic (civil). We map your entered Gregorian day at noon, without a sunset boundary. Religious observance, local moon sighting and sunset conventions can differ by a day.

A rabbit in the Moon

The dark lunar maria invite many readings. Royal Museums Greenwich documents the Moon Rabbit in Chinese and other East Asian stories, and the familiar Man in the Moon in European traditions. The same surface, different stories.

Orion, across different skies

The modern Western chart joins stars into Orion. In Māori sky knowledge, the three belt stars form Tautoru. These traditions organize and describe the same sky differently; one map is not universal.

Venus: a planet with many names

The planet is named after the Roman goddess of love and beauty. It is also the brightest planet in our sky. A cultural association is separate from its physical properties.
