While a person's personality and traits are almost entirely built on genes and environment, many believe that a few characteristics can be determined by the month in which they were born. Each person's birth date determines their specific zodiac sign in astrology, and those zodiac signs allude to their personalities in different ways.

The show Friends is filled with many different characters, each with their own unique personality. Although the characters' birthdays aren't entirely clear on the show, their personalities definitely are. So, fans can connect with a particular character based on their presumed zodiac compatibility.

January - Phoebe

January is a month predominantly connected to the zodiac sign, Capricorn, a strong-willed and disciplined sign that is knowledgable in several ways. Phoebe, with her Aquarian traits, would be the perfect soulmate.

Individuals born in January might find they are well-organized regarding time and self-control. They know how to manage their schedules and tasks efficiently and always stay on top. They need someone like Phoebe to shake up their lives a bit and push them to try new things. While both signs are independent, they allow each other space, when needed.

February - Ross

February is the month of Aquarius, and people born in this month are prone to being eccentric and fun-loving. While they might not like dull situations, they are open to all walks of life and appreciate intellectual conversations, which is why they could put up with Ross' worst and best traits.

Ross is the perfect soulmate for the independent and humanitarian Aquarians of February. The two would create a perfect balance of staying organized and living in the moment. They share a common ion for fighting for their causes and standing up against prejudice. The two will know when it is the time for space, time to have a calm conversation, and when they can be silly together.

March - Monica

March is the month of the sign Pisces, and they are dreamers and lovers alike. They have big imaginations and attach to grand ideas that allow them to be artistic. They need a soulmate like Virgo Monica to bring them back to reality once in a while.

Monica is a hard-working and practical person who loves to keep things clean and organized. While the Pisceans of March may seem like the polar opposite, someone like Monica is exactly who they need in their lives. While they can dream up any possible grand gesture of wildest fantasy, Monica's practicality will allow those imaginations to become a reality by putting them into action.

April - Rachel

April is the month predominately ruled by the zodiac sign, Aries. These fiery signs are confident and outspoken, always working towards whatever their goals might be. However, they need the scales of Libra, like Rachel, to balance them out.

There are many life lessons to be learned from Rachel. While she may seem superficial and materialistic, she is all about harmony. She knows how to talk to people and be gracious when they make mistakes, which Aries sometimes struggles with. Rachel could teach that impatient and speedy Ram how to slow down and appreciate the little things in life, while striving for their dreams.

May - Carol

May is the month of the bull, Taurus. Taureans long for someone reliable and devoted to the relationship and life as much as they are. They need to know they can trust their partner and appreciate the little things in life together. This is why the grounded bull would find a great soulmate in the family-oriented Carol.

Carol represents Cancer, a highly emotional but loyal and sympathetic sign. Taurus and Cancer are the perfect partners for each other because they love nurturing others and are okay staying home and just being together. While Carol might need a steady reminder that she can trust and rely on her partner for security, Taureans will have no problem showing just how devoted and steadfast they are for her.

June - Janice

June is most closely associated with the sign Gemini, a bright, optimistic personality with the ability to change and adapt as necessary. This sign needs someone who will bounce off their energy and be willing to follow their curiosities—someone like the Sagittarian Janice.

These two signs go together like bread and butter. They both are social butterflies who love to communicate, be the life of the party, and travel freely. The two will be able to communicate openly about their emotions. Janice will appreciate the affectionate and easily malleable Gemini, who will participate and accept her quirks and spontaneity.

July - Gunther

The zodiac Cancer rules July, and while it may be the most emotional and pessimistic of the zodiac signs, there is no better sign to be partnered with than the steadfast bull of Taurus — which guarantees those under Cancer a loyal companion, like Gunther.

Though Gunther might be stubborn and shy, he will make for the most loyal partner. He is a responsible individual with a practical approach to life and will be patient with any of Cancer's mood swings. Even though Cancers might require a little more reassurance than most other zodiac signs, Gunther would be quick to give it to them and prove just how reliable he is.

August - Richard

August is most closely connected to the lion of Leo. This fierce, powerful sign has no problem taking charge of any situation. They will speak their mind at all costs and refuse to be ignored, which is why they need a quiet and understanding partner in a Scorpio like Richard.

Scorpios are equally as powerful and ionate in their beliefs as Leos, but they know when to be silent and assess a situation. Like Richard, they have a unique ability to read others' speech and behavior and know exactly how they are feeling. This allows them to approach each situation delicately. On the other hand, Leos can help tightly wound Scorpios, like Richard, to relax and have fun rather than constantly overthink things.

September - Emily

September is the month of Virgos, and they are practical and analytic, always working hard and staying organized. Their methodical concentration on the finer details means they sometimes get stressed out and never feel as though they are good enough, which is they need a partner like the Piscean Emily.

Like Emily, those under the Pisces sign tend to see things more intuitively and approach things from a more cerebral state rather than focusing on the pure practical details. This is why they would make a good partner for Virgos, allowing them to broaden their horizons and see things from a different perspective. At the same time, a Virgo would help the dreamy Emily stop imagining how things could be better and instead appreciate the things right in front of her.

October - Mike

The month of October is all about the balanced Libra. They are fully cooperative individuals, keen on keeping harmony with and for people around them. They can sometimes be a bit indecisive when making decisions, which is why they need a partner like the enthusiastic Mike to push them forward.

Libras need some help feeling confident and sure of themselves and their decisions. That's why someone closely related to the Aries sign, like Mike, would make for the perfect partner. Mike's ionate, honest, and determined attitude will help his Libra partner propel themselves through any conflict or confrontation they might avoid and fully achieve their goals and potential.

November - Joey

The month of November is predominately connected to the zodiac sign, Scorpio. This highly-intuitive sign is ionate and resourceful. Joey's confident and playful personality is what Scorpio longs for in a partner, and Joey has proven his loyalty throughout Friends, time and time again.

Scorpios need a partner who will mirror their determination and focus in life while reminding them to stay present in the moment. While Joey is a confident and outspoken person, capable of taking control of any situation, he also has a fun-loving, silly side. The mysterious and intuitive Scorpio needs someone like Joey to lighten the mood, while also standing with them in their beliefs.

December - Chandler

The spontaneous, fun-loving Sagittarians who rule the month of December need a partner in crime. What better zodiac sign to match as their soulmate than the equally as curious and affectionate Gemini.

Chandler is a quick-witted, silly individual who would know how to adapt quickly to his Sagitattirus partner's spontaneous actions. Geminis and Sagittarians are both known for being social butterflies. Chandler has already proven he is the funniest character in Friends, something that his Sagittarian partner would appreciate. He would also keep them realistically grounded with his more serious approach to matters when needed.
