nativity

Nativity refers to the circumstances of someone's birth—the time, place, and conditions of being born.

The word appears most often in religious or formal contexts: a nativity scene, the place of her nativity.

In astrology, a nativity is a horoscope cast for the moment of birth.

The word carries an archaic or elevated tone in general use. (Capitalized Nativity refers specifically to the birth of Jesus Christ.)
