If you were born on June 20, your astrological sign is Gemini. June 20 is the last day of the Gemini season. So, those born on this day are on the cusp between Gemini and Cancer, though they fall squarely into the sign of Gemini. However, people born on a cusp may have different traits than other Geminis.

Additionally, Gemini is just the sun sign for people born on June 20. Each person born on this day has a completely different full astrological chart based on their year, time, and location of birth. A full chart reading and analysis will give you even more insight into yourself as your own personal astrology has influenced it.

June 20 Zodiac Sign: Gemini

Geminis born on June 20th are adaptable and outgoing.

Gemini is the sun sign for anyone born between May 21 and June 20. In general, Geminis are curious, social, and intellectual. Geminis are quick thinkers. They love change, and they love learning new things. This can lead them to become someone who knows a little bit about everything.

This fuels one of their main loves, conversations and the written word. Their vast library of knowledge gives them something to add to any exchange, whether spoken or written. A more difficult aspect of this trait is that insecure Geminis may develop imposter syndrome or feel they can not master anything.

Geminis love novelty. To people of other signs, they may appear to carelessly flit from one thing to the next, whether that is a job or a relationship, but to a Gemini, this behavior is satisfying their curiosity and making them happy.

June 20 Zodiac: Gemini/Cancer Cusp

People who are born between June 18 and 24 are on the cusp between Gemini and Cancer and have some special traits that other people in their sign may not have. People born on June 20 can be Gemini with a touch of Cancer. This time frame is also known as “the cusp of magic.” So, they may be more emotional and more romantic than other Geminis. However, there can be some friction between emotional Cancer traits and logical Gemini traits. People born on June 20 may feel strong emotions but have difficulty expressing them.

The Decans of Gemini

Each sun sign in astrology has three decans. These are (about) 10-day sections of each sign that have slightly different traits. The decans are actually based on degrees in the astrology chart. The chart is a circle and each sun sign represents 30 degrees. Each sign is broken down into 10-degree sections for each decan.

The first decan of Gemini goes from May 21 to May 31. Mercury rules this decan, as is the sign of Gemini, so these Geminis are extra Gemini! The second decan goes from June 1 to June 10. Those born in this decan are extra romantic and flirtatious because Venus rules it.

People born on June 20 fall into the third decan of Gemini, which runs from June 11 to June 20. Uranus and Saturn rule them. Third decan Geminis can be a bit more serious and less social than other Geminis. They may not have as wide of a friend group, but that is only because they devote so much time to their hobbies and interests. They love adventures and want to hang with people who can keep up with them, and keep their word about what they say they are going to do. Luckily, third decan Geminis can be natural leaders, so they are happy to take the helm and make the adventure happen with their loyal companions.

June 20 Zodiac Ruling Planet: Mercury

Mercury is the ruling planet for Gemini individuals with a June 20th birthdate.

Have you ever heard of the term mercurial? It comes from the ancient god Mercury (the Roman analog to the Greek Hermes), which is also the origin of the name of the planet that rules over Gemini. So, it shouldn’t come as a surprise that some Geminis are considered mercurial, which means they are prone to suddenly change their mind or their mood.

Mercury is the planet of thought, travel, communication, commerce, and thieving. This points to Gemini’s many sides and interests. As an ancient deity, Mercury was quite social and was the messenger of the gods. So, he had to travel around and pass messages to different people. He was one of the few gods that could easily travel back and forth between Mount Olympus, the mountain of the gods, and the underworld of the dead. This is similar to Gemini’s tendency to move between multiple social groups and ability to make friends with anyone.

June 20 Zodiac Element: Air

Each sign in the zodiac is ruled by one of the four elements: air, fire, water, or earth. Gemini is an air sign. People with air signs are generally very social and curious. The other two air signs, Libra and Aquarius, love helping others more than Gemini. Gemini is great at helping the people they love because their high social intelligence gives them a unique talent for understanding people. However, they may not be as likely as a Libra or Aquarius to do activism or humanitarian work.

People of all air signs can have fast-moving interests and moods that change quickly. They may seem quirky and off-beat to others. But, it’s really just that they follow their interests and passions wherever they may lead.

June 20 Zodiac: Mutable

Gemini is a mutable sign, like Pisces, Virgo, and Sagittarius. People with mutable signs are more adaptable and flexible than people with fixed or cardinal signs. However, in their more difficult moments, they can make poorly thought-out decisions or become very anxious about the choices they have to make.

The other types of signs are fixed and cardinal. People with fixed signs, including Aquarius, Taurus, Leo, and Scorpio, love adhering to a plan and can be a bit headstrong. People with cardinal signs, like Capricorn, Aries, Cancer, and Libra, often lead the pack but struggle with feeling restless.

June 20 Numerology & Other Associations

To get your full birth date numerology, you would take your full birth date, including the year, and add it all up. For example, if you were born in 1985, you would do 1 + 9 + 8 + 5, which equals 23. Then you would add 23 + 6 (for June) + 20, which equals 49. You would then add 9 + 4, which equals 13. To finally simplify the number, you would add 1 + 3, which leads to a life path number of 4.

However, just the month and date have their own numerological qualities. The number 20 reduces down to the number 2. Those with number 2 traits have some Gemini qualities! They are very social. However, while Geminis tend to be independent, number 2s usually work well with others. So, Geminis born on June 20th may enjoy group projects more than others.

When we add the month (6) plus the date number 2, we get 8. People with the number 8 are often driven professionally and can find commercial success. Geminis born on June 20th may find themselves succeeding in the business world, especially when they work on a team in an environment that is always changing.

June 20 Birthstone

While some months only get one birthstone option, those born in June get three. Sometimes, when one type of birthstone becomes too rare of a find, gemstone associations will pick another one. Additionally, most months have a traditional gemstone option and a more modern one.

For those born in June, the pearl is considered the traditional option, and the alexandrite is the more modern choice. However, Moonstone is also an official gemstone for the month.

June 20 Zodiac: Personality and Traits


A Gemini often has a love of learning.

It’s important to note that any sign can manifest in a number of different ways. What’s listed here are basically stereotypes about someone with the sun sign of Gemini. However, other aspects of their charts can influence people’s personalities, including their moon sign, rising sign, and much more. So, it’s not advisable to make judgments about people based on their sun signs before you know much about them. Some typical Gemini traits include:

  • A love of learning
  • Great conversationalists
  • Gossips
  • Intelligent
  • Fast-moving and thinking
  • Analytical
  • Logic-based
  • Energetic
  • Easily change their mind
  • Youthful
  • Nontraditional
  • Playful
  • Curious

Geminis have a reputation for being “two-faced” however, this is not true at all. Most Geminis do not have bad intentions when they change their minds quickly or lose interest in a new friend or lover overnight. It is simply their nature to change their minds; they must go wherever their interest or passion takes them. So, if a Gemini does something that you consider “two-faced,” it’s important not to take it personally. It’s not about you. It’s just about their own drive to follow their interests.

Gemini/Cancer Cusp Personality Traits

Because those born on June 20th fall on the cusp of Cancer, there are some other personality traits to consider. They have all the Gemini personality traits but may also be slightly more romantic and empathetic than other Geminis. They also feel a lot. Cancer is ruled by the moon, which makes it a more emotional sign than Gemini, which is all about logic. So, those born during the cusp of magic can have big feelings that conflict with a desire for order and reason. Because of this, June 20 Geminis sometimes have trouble recognizing and acknowledging difficult feelings, causing them to brew below the surface, leading to inner anxiety and tension.

June 20 Zodiac: Career and Passions

A Gemini excels at communications.

Geminis often do best when they work for themselves as an independent contractor. This allows them to have new energy in their lives and flow in whatever direction their interests take them.

Some careers that may interest Geminis include anything that involves communications. Geminis make great public relationships with representatives, journalists, and social media managers. They also do well in anything with a fast-paced environment where things are always changing. So, they may love being a project manager or doing event planning. Charming Geminis are wonderful salespeople. Their love for analysis and logic-based thinking can also lead them to become data or digital security analysts.

June 20 Zodiac: Hobbies

Geminis love hobbies that allow them to learn new things, engage with other people, or stimulate their intellect. Simple hobbies like reading or doing crossword puzzles can be a big draw for Geminis. However, they can also enjoy hobbies that require quick thinking, like SCUBA diving or motorcycle riding.

June 20 Zodiac in Relationships

Geminis are traditionally very flirtatious; some can have a wandering eye in relationships. That is why some Geminis may feel drawn to ethical non-monogamy or other non-traditional lifestyles that allow them to explore their crushes. However, Geminis born on June 20th have a bit of Cancer flavor mixed in. This adds a more romantic side to them that does love commitment and partnership.

Geminis make really fun dates. They always have something to talk about and are great at coming up with fun ideas for things to do. Another useful quality in Geminis is that they tend not to get too hung up on relationships that didn’t work out or bad dates. They tend to move on quickly because their attention is drawn to something new.

Compatibility for June 20 Zodiac

Those born during the cusp of magic on June 20th have different compatible signs than other Geminis. They may get along well with water signs, including Cancer, Scorpio, and Pisces, because of their own touch of Cancer. Other Geminis often clash with these signs because the Gemini logic-based approach sometimes does not vibe well with more emotional water signs.

June 20th Geminis also get along well with fire signs Aries, Leo, and Sagitarrius. Both of these signs love adventure, and airy Gemini can fuel a fire sign’s flames.

Geminis may not get along well with earth signs Capricorn, Taurus, and Virgo. These signs can be traditional and stubborn, which is the antithesis of Geminis ethos.

June 20 Zodiac: Mythology

Much of what we know about astrological traits can be attributed to ancient Greek mythology. The symbol of Gemini is the twins Castor and Polydeuces (or Pollux in Roman mythology). They aren’t exactly twins, however. They were born at the same time but had different fathers. Castor was mortal, as he was the son of the King of Sparta, Tyndareus, and Pollux was immortal, as the son of Zeus. They had the same mother – Leda, a beautiful queen who was tricked into having sex with Zeus when he took the shape of a swan.

When Castor died in a battle, Polydeuces also pleaded with his father, Zeus, to make Castor immortal. Zeus made a compromise allowing Polydeuces to give Castor half his immortality. So, the twins had to spend half of the time in the underworld of the dead, and the other half of the time they could enjoy Mount Olympus. This speaks to Gemini’s ability to move between communities and fit into any social scene.

Additionally, the planet Mercury, the ruling planet of Gemini, has its own mythology that can explain some of the sign’s traits. Like the twins, the planet’s mythological god namesake could move seamlessly between the underworld and the overworld. In fact, one of his duties was escorting people who had died to the world of the dead. As the messenger of the gods, Mercury had wings on his feet, which made him as speedy as any Gemini. He also had the gift of the gab, passing on messages with the communicative skills that we associate with the sign today.

  1. The signing of the Treaty of Versailles (1919): On June 20th, 1919, the Treaty of Versailles was signed in the Hall of Mirrors at the Palace of Versailles near Paris, France. This treaty officially marked the end of World War I and established peace terms between Germany and the Allied powers.
