Your sign: Sagittarius ♐
A December 15 birthday lands in Sagittarius (Nov 22 - Dec 21), the mutable fire sign ruled by Jupiter. On the 15th of December the Sun travels near the 24th degree of Sagittarius, late in the sign's month-long season - day 24 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. Optimism in your hands is not naivety; it is a strategy with a remarkably good track record.
Your decan
Each sign spans three decans, and the 15th of December falls in the 3rd decan of Sagittarius, the stretch tradition co-rules through Leo and its planet the Sun. A Leo undercurrent gives this stretch its glow - the part of you that makes ordinary occasions feel slightly ceremonial.
Your birthday number: 6
Long before you chose a favorite number, one chose you - the date on the calendar square where your story starts keeping count. Born on the 15th, you carry the birthday number 6. Responsibility settles on your shoulders like a well-worn coat, and people lean on you because you have never once shrugged it off. You are the one who notices the empty cup and refills it before anyone thinks to ask. Generosity comes standard with a birthday on the 15th, along with a magnetic sort of homemaking charm. Loved ones orbit you naturally, drawn by the promise of good food, honest counsel, and a genuinely comfortable chair.
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 15 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 15 Sagittarius pairs most naturally with Aries, Leo and Gemini. For friendship the same arithmetic tilts toward Aries. Treat the list as a head start rather than a verdict - plenty of the zodiac's best marriages score terribly on paper.
The one thing to remember
A birthday sets the key a life is written in, not the melody: plenty of people transpose theirs entirely, and the ones who do tend to credit the original key for teaching them music.
