Harry Potter Zodiac Sign & Birth Chart Meaning

Harry Potter Zodiac Sign & Birth Chart Meaning

J.K. Rowling says that Harry Potter was born on 31st July 1980, making him a confident, caring, and courageous Leo. Harry, like most people born under this zodiac sign, has an air of “royalty” about him, despite his humble upbringing (in a closet).

People born under this sign are extremely generous and loyal to those that they love, and capable of tremendous courage.

Harry’s birthday is an extremely important plot piece in the Harry Potter books, as it is one of the principal elements that ties him to Lord Voldemort and the prophecy. So, what else can his astrological chart tell us about the character?

Harry Potter’s Sun Sign – Leo

Leo Zodiac Sign Symbol with Dates

Your sun sign reflects your principal traits that form the basis of your personality. Harry’s Leo traits come through extremely strongly throughout his time at Hogwarts.

Leos tend to be very confident and rarely question their abilities. While Harry doesn’t always excel, he never suffers from the same fear of failure as his friend Ron Weasley. And when he is thrown into unpredictable situations for which he is not prepared, such as the Triwizard Tournament, in his mind, he has just as good a chance as his more experienced competitors.

People born under this sign often have a lot of charisma, which makes others believe that they are capable of something special. This is something that Harry exudes and is why he often finds himself reluctantly in the spotlight.

He is bold and impulsive, following his instincts rather than developing carefully laid plans like his friend Hermione Granger. His default response to most things is courage and compassion.

But like most Leos, Harry is a bit egocentric, and the world revolves around him (the books are named after him after all). But he often doesn’t consider how his actions will affect the people closest to him.

Fun fact – Daniel Radcliffe, the actor who plays Harry Potter in the movies, is also a Leo.

Harry Potter’s Moon Sign – Pisces

J.K. Rowling never tells us Harry’s exact time of birth, so it is difficult to determine other elements of his natal chart, such as his moon sign and his ascendant sign. However, if we assume that Hagrid burst in on the Dursleys on Harry’s 11th birthday at around the time of his birth, then he was born shortly after midnight, making him a Pisces Moon.

Your moon sign reflects how you think, your inner world, and your emotional tendencies. It can have an even stronger influence on your personality if you were born at night, as Harry would have been if he was born shortly after midnight.

This is no surprise as people born with a Pisces moon have a natural magical quality, and Harry is a naturally talented wizard.

Pisces moon also explains his compassion and his innate tendency to want to help those weaker and less fortunate than him. We see this repeatedly with Buckbeak, Dobby, Luna, and scores of other characters.

Harry Potter’s Ascendant Sign – Taurus

Your ascendant sign reveals how you relate to other people and where you view your place in the world. According to our calculations, Harry is an ascendant in Taurus.

Taurus ascendant would explain Harry Potter’s reluctance to be in the spotlight and natural modesty. Harry just wants to be “normal”. This also indicates Harry’s brooding nature. He often keeps his own council and ruminates on problems while hiding his true feelings from the people around him.

Harry Potter’s Personal Planets

The placement of Mercury, Venus, and Mars reveals further insights into our personalities, which is why they are called personal plants.

The placement of the more distant plants are considered generational, as the long time that they take to transit the signs means that they affect entire generations.

Mercury in Cancer

The position of Mercury reflects logic and communication. With Mercury in Cancer, Harry places a lot of faith in his intuition and always follows his gut, even if it conflicts with logic and reason.

This also indicates an innate honesty and a need to say what is on your mind. This is something Harry often does, getting him in trouble at school and with the Ministry of Magic.

Venus in Gemini

Venus reflects your approach to love and romance. While Gemini suggests someone who is always falling in and out of love, something that we don’t see much of in Harry (unlike Ron), it can also reflect a fear of commitment.

Harry is very reluctant to take things forward with both Cho Chang and Ginny, often changing his mind about what he wants the status of their relationship to be.

Mars in Libra

Mars represents how we manage conflict, and its placement in Libra suggests that Harry is driven to resolve conflict peacefully.

While Harry isn’t afraid to fight for what is right, he does prefer resolutions that protect others, which is why he is happy to sacrifice himself in The Deathly Hallows. Plus, he is always playing peacekeeper between Ron and Hermione.


What does Harry Potter’s natal chart mean for his relationships with the people he is closest to, such as Ron, Hermione, and Ginny, and his connection with his nemeses, such as Lord Voldemort and Draco Malfoy?

Ron Weasley is a Pisces, which means that he is a generous friend, but also the type to hook his wagon to a stronger best friend, like Harry.

In turn, since Harry’s ascendant is in Pisces, he will have a natural affinity to Ron and understand his more perplexing personality traits well.

Ron sums up his friendship with Harry perfectly in The Half-Blood Prince: “We’re with you whatever happens.”

Hermione Granger is a Virgo, explaining her intelligence and meticulous approach to everything. This explains why the two often get frustrated with one another, as they think in fundamentally different ways. But there is a lot of mutual respect between these two signs.

Hermione makes her respect for Harry clear from the first book: “Books and cleverness! There are more important things – friendship and bravery.”

Ginny Weasley is a Leo, which explains why she and Harry are attracted to one another as fellow fire signs, but also why they butt heads. They are both naturally dominant and confident.

There is no way that Ginny will just wait around while Harry is off saving the world. Instead, she leads a school revolt (with fellow Leo Neville Longbottom).

Draco Malfoy is a Gemini, which explains why he is easily led and worries significantly about appearances.

While Harry’s Leo has little natural patience for this, in other circumstances the two could have been friends as they would never run out of things to talk about.

Lord Voldemort is a Capricorn, which places him naturally at odds with Harry’s Leo. While Leo leads with the heart, Capricorn leads with the head and can be scheming as well as meticulous.

The two can learn a lot from one another, but their innate needs and priorities are fundamentally different.
