Birth Sky
The exact sky of your birth

The sky, the moment you were born.
Every sky exists only once. Because Earth, the stars, and the planets are constantly in motion, no view of the night sky ever repeats. You were born under a sky that had never existed before and will never exist again. That makes it a fingerprint over your head.
Birth Sky calculates what your sky looked like the moment you were born. It shows the real stars and planets as they stood at that instant, and finds the catalogued star closest to directly over your head: your zenith star. Then it tells you its story.
Not astrology. A personal connection to real astronomy.
