Born on December 21, 1977?

The Sun, Mercury, Venus and Neptune were all in Sagittarius, so everyone born that day is a Sagittarius several times over. The Sun and Mercury sat less than a degree apart in Sagittarius, a close conjunction shared by every chart from that day.

Planet signs are only part of the picture. Your rising sign changes about every two hours and the Moon moves half a degree an hour, so your exact birth time and place decide your houses, angles and Moon degree.
