Born on December 13

Your sign: Sagittarius ♐

A December 13 birthday lands in Sagittarius (Nov 22 - Dec 21), the mutable fire sign ruled by Jupiter. On the 13th of December the Sun travels near the 22nd degree of Sagittarius, late in the sign's month-long season - day 22 of the Sagittarius year. Jupiter rules your sign and it shows in the scale of your appetite - for places, ideas, questions, and second helpings of all three. Honesty comes off you unfiltered, which costs you occasionally and makes you trusted permanently.

Your decan

Each sign spans three decans, and the 13th of December falls in the 3rd decan of Sagittarius, the stretch tradition co-rules through Leo and its planet the Sun. Leo in the co-pilot seat turns the brightness up: more warmth, more drama, more instinct for the memorable gesture.

Your birthday number: 4

Your birth day number is small arithmetic with long consequences, a single digit or two quietly doing sums beneath your personality. Born on the 13th, you carry the birthday number 4. Reliability like yours is rarer than people admit, the kind that shows up on moving day with a truck and rope. Grand visions interest you less than sound foundations, since you know every cathedral began as someone checking the ground. The 13th gets an unfair reputation, when in truth it produces some of the steadiest architects of order on the calendar. Hard-won order is your signature move, and you sort chaos into structure as casually as other people stir milk into coffee.

The season you arrived in

December babies arrive with the year's shortest days and its most lights per window, which is why you know darkness is mostly a decorating opportunity. Having a birthday wedged among the holidays taught you to share a stage gracefully, and to notice the one gift wrapped in birthday paper instead of snowmen. Layer that over a yang fire sign and you get the particular December 13 blend: the season sets the stage, the sign does the talking.

In love

By the traditional scorecard - elements, modalities, and the aspects between signs - a December 13 Sagittarius pairs most naturally with Aries, Leo and Gemini. Friendship runs on slightly different math, and there it is Aries who comes out ahead. Ease is not the whole story, though: the harder pairings grow people faster, and every match writes its own exceptions.

The one thing to remember

A birth date is a pencil sketch, a few confident lines on good paper, and the shading, the color, and the figure walking out of the frame are yours to add.
