What gives you away
Three signs you’re the Aries decan
01You jump before you look
You jump off the rock while everyone else is still testing the water. You take the karaoke slot nobody wants. You're the one who signs up for the half-marathon before checking the date.
The astrologyMars is the planet astrologers link with nerve and action. Mixed into Sagittarius’ love of risk, it makes waiting around feel almost painful.
02You turn everything into a competition
You've turned a walk to the shop into a race and won it in flip-flops. You keep score in games nobody else knew were games, like who finishes their coffee first. If someone says it can't be done, it becomes your whole weekend project.
The astrologyAries is the sign of the starting line, and in astrology Mars is about winning. So this decan needs something to aim at.
03You stick up for people out loud
You're the one who tells the waiter, kindly and clearly, that your friend's order came out wrong. You've argued with a customer service line for a friend who was too nervous to call. When something's unfair, you can't let it go until you've said something.
The astrologyAstrologers link Sagittarius with beliefs and fairness, and Mars with standing your ground. Together they make you the one who speaks up.
Why you’re like this
How Sagittarius’ decans work
Each zodiac sign covers 30 degrees of the sky. Astrologers split every sign into three 10-degree slices called decans, and the Sun spends about ten days in each one.
Sagittarius is a fire sign. In the decan system most popular in modern astrology, each third of a sign mixes in a sign of the same element, in order. The middle third mixes in Aries, the fire sign that starts the zodiac. Aries is ruled by Mars, the planet astrologers tie to courage, speed and competition.
Love
The Aries decan in love
You like the chase, and you're happy to make the first move. Sending the risky text beats a week of wondering. A date with something physical in it, like climbing, dancing or go-karts, tells you more than three dinners would.
You need someone who can keep up and will say yes to the climb, the dare or the 6 a.m. hike. A good argument followed by a laugh is close to your idea of romance. Someone who sulks for days instead of saying what's wrong wears you out.
If you love one
Say it straight to their face. The Aries decan respects a direct “I'm upset” far more than hints dropped over a week.

At work
You work best with a goal, a deadline and a little risk. Give this decan the project nobody wants to start and you'll have a first draft before anyone else has opened the file. Astrologers often match this decan with sports, fitness, emergency work, sales, startups and jobs outdoors.
The hard part
When it gets heavy
Your fast start can burn out halfway. You quit something in a flash of anger, promise more than one week can hold, or pick a fight because sitting still feels worse.
Give yourself one night's sleep before the big decision or the angry text. If it still feels right in the morning, go for it, and you'll have the whole day to do it.

Frequently asked questions
What dates are Sagittarius decan 2?
In most years, December 2 to 11. The Sun reaches 10° Sagittarius on December 1, 2 or 3 depending on the year and time zone, and reaches 20° on December 11, 12 or 13 (we checked every year from 1940 to 2026 with the Swiss Ephemeris). Born on one of those days? Use the decan checker on this page, or your free birth chart.
I was born on December 11, 12 or 13. Am I decan 2 or decan 3?
It depends on the year, and sometimes on the hour. The Sun reaches 20° Sagittarius on December 11, 12 or 13, depending on the year and where you were born. Put your birthday into the decan checker above. If it says your birth time decides, your free birth chart settles it.
Why is the Aries decan the most impatient Sagittarius?
Because Aries, the sign mixed in here, is the zodiac's starter, and its planet Mars likes fast results. Sagittarius already wants to be somewhere new, and this decan wants to be there by lunch.
Do decans work for my rising sign or Moon too?
Yes. Any planet or point in Sagittarius has a decan, set by its degree. A Sagittarius rising at 15°, for example, is in the Aries decan, even if your Sun is in another sign. Your rising degree needs your exact birth time, and your free birth chart shows it.
Which decan system does ZODIA use?
The triplicity system, the most popular one in modern astrology. Each decan mixes in a sign of the same element, so Sagittarius goes Sagittarius, Aries, Leo. Older Hellenistic astrology used a different set called the Chaldean faces, which gives Sagittarius’ thirds to Mercury, the Moon and Saturn. Both are real traditions.
Is my decan my whole personality?
No. Your decan sharpens your Sun sign, and your Sun is one part of your chart. Your Moon shapes how you feel, your rising shapes how you come across, and your Venus and Mars shape how you love and go after things. Two people born on the same day can still be very different.
