Are you a December 12 zodiac sign? If you were born on this day, you are a Sagittarius! This sign of the zodiac is bold, adventurous, and passionate about new experiences. Astrology can be a fascinating and informative practice, something that is more social than scientific. However, this ancient methodology could be insightful into your own personality, especially if December 12th is your birthday. 

A Sagittarius is most compatible with a Gemini, Pisces, Aquarius, or Leo.

In this article, we will discuss the fundamentals of astrology and how they influence someone born on the 12th of December. Not only will we go into detail when it comes to the Sagittarius personality, we will also discuss this specific birthday from an astrological and numerological perspective. Let’s get started and lend you some astrological insights into your potential for love, success at work, and so much more! 

December 12 Zodiac Sign: Sagittarius

Sagittarian energy is tireless, optimistic, adventurous, and independent.


There are a number of fundamental things to discuss about astrology before we can truly encapsulate the personality of the average Sagittarius. For example, Sagittarians are the 9th sign of the zodiac, following Scorpio. Neighboring signs of the zodiac learn lessons from each other. Scorpio teaches Sagittarius the importance of connecting to others as well as living life with intensity. This is only one reason why Sagittarians are so motivated to connect to people from all walks of life and learn about them so that they can further their own passions. 

Speaking of passions, Sagittarians are fire signs, which is the most energetic and curious element of the zodiac. Sagittarian energy is tireless, optimistic, adventurous, and independent. Independence is a very important word to associate with fire signs and especially Sagittarians, as they live their life seeking it at all times. The straightforward and bold natures of fire signs help them further their goals and communicate how they feel clearly, albeit bluntly, from time to time!

The final fundamental astrological concept to discuss is the concept of modalities. All signs of the zodiac have a modality associated with them, something that corresponds with the time of year that their season happens. Sagittarius season occurs as fall becomes winter, at least in the northern hemisphere. This means that Sagittarians are mutable signs of the zodiac, which makes them adaptable, changeable, and flexible. Mutable signs reflect the variable and unreliable temperatures of the time of year that they are born during. 

But this is only the beginning of our investigation into the Sagittarian personality. What makes a Sagittarius so keen on adventure, and is there something that directly influences their motivations? For that answer, we turn to the basis of astrology: the planets. 

Jupiter: the Ruling Planet of a December 12 Zodiac

Discovering things as an individual and learning lessons that promote self-growth are all important things that Jupiter lends to Sagittarius.


The largest planet of our solar system rules over Sagittarius, which may be why this fire sign has such a big personality! Jupiter is a planet associated with bounty, luck, philosophical expansion, and journeying. It is a generous and positive planet, one that allows us to grow without too much stress, unlike its neighboring planet, Saturn. Jupiter rules over Sagittarius and lends this sign of the zodiac many of its positive and generous traits. 

For example, Sagittarians are incredibly optimistic people. They are born with an instinct that tells them everything will work out in the end. While Sagittarians often remain optimistic about the future and forget to live in the present, Jupiter ensures that this sign of the zodiac rarely struggles with self-doubt. The Sagittarian glass is usually half full, as this fire sign believes everything happens for a reason. Jupiter is also a lucky planet. Sagittarians seem to be a little lucky as well! 

The philosophical desire to learn more and uncover answers to some of life’s biggest questions comes from Jupiter. Sagittarians often devote their lives to the pursuit of these answers, thanks to Jupiter. They value inner expansion, as this appeals to their independent natures. Discovering things as an individual and learning lessons that promote self-growth are all important things that Jupiter lends to Sagittarius. 

However, the largest planet in our solar system can get a bit boastful from time to time. It’s important for the average Sagittarius to remember that we are all on our own journeys, and some of our paths are not as positive as the Sagittarius path. The largesse of this fire sign can come across as braggy or greedy to some, so it’s important for Sagittarians to attempt humility from time to time! 

December 12 Zodiac: Strengths, Weaknesses, and Personality of a Sagittarius

Ultimately, Sagittarians crave freedom and independence over all things.

The optimism of a Sagittarius is truly one of their biggest strengths. Curious, clever, and always dreaming, Sagittarians believe in seizing the day, no matter the day. There is a hunger in this zodiac sign, one that is rarely sated. Sagittarians are always seeking more, whether that means more new experiences, more knowledge, or more money. They always believe that there is something bigger and better around the corner, at their destination, in the eyes of someone new.

While constantly seeking more isn’t always a bad thing, one of the true weaknesses of Sagittarius is that this sign struggles to appreciate the present. Allergic to nostalgia, Sagittarians are always forward-thinking and excited about the unknown. Their optimism allows them to view unknown circumstances as an excitable challenge. But this excitement makes present circumstances and things that are familiar boring. 

Sagittarians are intellectual and empathetic to the plights of others. They long to understand others but only because they view new information as a way to better understand themselves. This sign of the zodiac is notorious for voicing their strong opinions, only to have those opinions shift or change in a matter of days. The mutable modality of Sagittarius makes them prone to change and adapt when they receive new information. However, their fiery elemental placement lends them strong opinions, even if they don’t believe in them forever! 

Ultimately, Sagittarians crave freedom and independence over all things. This can make them incredibly individualistic, which can be isolating. Sagittarians often abandon places, people, and things in their search for something greater. While admirable and ambitious, the life of a Sagittarius can occasionally feel lonely. 

Numerology for a December 12 Zodiac: 12 and 3

A Sagittarius so connected to the number 3 may be adept at communicating.


There are two very important numbers to address when we consider a December 12th birthday. The number 12 is obviously important, as both the month and date align. And, when we add the digits in the number 12, we get 3. The number 3 is an intelligent, powerful number, one associated with the third sign of the zodiac, Gemini. Astrology also speaks of the third house as the house of communication, but how do these things manifest in a Sagittarius birthday?

A Sagittarius so connected to the number 3 may be adept at communicating. This number speaks of intellectual prowess and the ability to communicate grand thoughts and ideas. These things align well with the Sagittarius personality and further enhance traits that are already there. A Sagittarius born on December 12th may find immense power in writing, public speaking, and communication in general. 

It’s important that we also mention the number 12, given this birthday has an undeniable connection to it. The 12th sign of the zodiac is Pisces, and the 12th house is known as the house of dreams, transformation, and escapism. A Sagittarius so connected to the number 12 may find that they long to transform through creative expression or escapism in their life. This is a beautiful thing to consider, but there are drawbacks to this as well. 

The 12th house can be risky when it comes to escapism. This house rules addictions and self-medication, something that this Sagittarius birthday may want to watch out for. This Sagittarius birthday may justify or excuse their behavior given their high intelligence and value for new experiences. However, it’s important to avoid self-medication or escapism behaviors, even if these scenarios can lead to otherworldly experiences!

As a mutable sign, Sagittarians do well in collaborative careers. Mutable signs are excellent when it comes to bridging the gap between beginnings and endings, filling in where necessary. Their flexibility and adaptability make them excellent coworkers and peers, though Sagittarians value their independence greatly. They aren’t opposed to working on a team, but the average Sagittarius will still need some solitude or control over their workplace schedule. 

Given their own pursuit of knowledge, Sagittarians enjoy helping others pursue theirs. This sign of the zodiac makes an excellent teacher, mentor, or advisor in many different fields. Higher education is associated with both the 9th house and Jupiter, so Sagittarians often pursue this for themselves. They are also likely to become college professors, someone who can inspire others to become their own independent person. 

Given this Sagittarian’s connection to the numbers 12 and 3, a December 12 zodiac sign may find themselves in a creative career. Communicating is important to this birthday, and they may enjoy a career in journalism, writing, public speaking, and more. Sagittarians are also fairly rebellious, and this birthday may make an excellent advocate for those who are trying to enact true change in our world. 

Finally, the energy of the average Sagittarius makes them adept in physical careers or careers that allow them to travel. In fact, traveling may matter greatly to this Sagittarius birthday. Whether they are social media influencers, pilots, or designers seeking inspiration, a career that allows a Sagittarius to travel is always a good idea! 

Relationships and Love for December 12 Zodiac Signs

Sagittarians enjoy partnering with someone of equal independence or at least someone who doesn’t cling to them.


Given their independent natures, Sagittarians aren’t exactly seeking long-term relationships. This isn’t to say that they don’t have them and that Sagittarians can’t commit for a long time. But, especially when this sign is young, Sagittarians prefer their independence over all things. They are quick to move on to someone or something better, even if they appeared all-in at the time of starting their relationship with someone. 

Passionate and optimistic about life, love, and everything in between, Sagittarians are exciting partners. They often Inspire who they are with and enjoy being with people who share their excitement for life. A Sagittarius born on December 12th will enjoy communicating their grand ideas with their partner, capable of talking about their latest passions for hours. 

Sagittarians enjoy partnering with someone of equal independence or at least someone who doesn’t cling to them. This is the quickest way to repel a Sagittarius and end a relationship with one! Placing too many boundaries on this mutable fire sign will upset and annoy them. It’s important to hold a Sagittarius responsible for their somewhat flighty actions, but know that this wanderer of the zodiac may wander anyway, no matter how good a relationship is! 

The good news is Sagittarians are straightforward in their style of communication, especially a Sagittarius born on December 12th. You will likely know how your Sagittarius is feeling, as they aren’t afraid to bring up conflicts or ill feelings. However, Sagittarians know that we are all individuals on our own individual paths, and they are often quick to seek someone whose path might better align with their own.

It all depends on the individual, as any Sagittarius will tell you! When we look at a December 12th zodiac sign in particular, here are some astrological matches for this Sagittarius birthday:

  • Gemini. The number 3 is very important in a December 12 zodiac birthday, which is why this Sagittarius may be especially drawn to Geminis.

  • Pisces. Given that this Sagittarius birthday is connected to the number 12, they may find the average Pisces appealing. Also mutable, Pisces offers Sagittarians an adaptability that they can respect. Pisces are also dreamy and creative, seeking the same answers that philosophical Sagittarians seek.
