The short version
If you were born December 12 to 21, you are Sagittarius warmed by Leo: adventurous and honest, now with charisma and a big heart. You are the most generous, expressive, crowd-pleasing Sagittarius, a born storyteller and host.
What makes Sagittarius decan 3 different
All three Sagittarius decans share the same core, but yours carries a second influence: Leo, ruled by the Sun. That sub-ruler does not replace your Sagittarius nature, it colors it, which is why a Sagittarius born December 12 to 21 can feel noticeably different from one born earlier or later in the sign.
Sagittarius decan 3 in love
In relationships, this is the Leo-flavored Sagittarius. You love generously and need to be appreciated for the size of your heart.
The shadow side
You can be dramatic, and you need more admiration than you usually let on. Knowing the pattern is the first step to not being run by it.
The dates in this decan
Sagittarius decan 3 covers these birthdays: December 12, December 13, December 14, December 15, December 16, December 17, December 18, December 19, December 20, and December 21. These boundaries shift by a day or two from year to year as the Sun moves, so if you were born right at the edge, your exact birth chart is the only way to know for certain which decan, or even which sign, you fall in.
Famous people born December 12 to 21
Famous people born December 12 to 21 include Milla Jovovich, Bill Pullman, Pope Francis, Jane Austen, Ludwig van Beethoven, Benjamin Bratt, and Jonah Hill. Sharing a decan with someone is a fun footnote, not a personality verdict; your Moon, rising, and the rest of your chart are still entirely your own.
The other two Sagittarius decans
Sagittarius comes in three flavors depending on which third of the sign you were born in. Read the other two: Sagittarius decan 1, Sagittarius decan 2. For the bigger picture, see the full Sagittarius compatibility guide or the Sagittarius sign page.
Why this is your sun-sign baseline, not your full chart
Your decan sharpens the picture, but it is still only the Sun. Your Moon (how you feel), your rising sign (how you meet the world), and your Venus and Mars (how you love and act) can change everything.
