People born in January are either a Capricorn (January 1–19) or an Aquarius (January 20-31). For most of the month, the earth sign Capricorns rules the first month of the year. With everyone burnt out financially and emotionally by the holiday season, Capricorns tend to get the short end of the stick when it comes to celebrating their birthday. Capricorns are the last earth sign of the zodiac, represented by the sea goat, a mythological creature with the body of a goat and the tail of a fish. This sign is known for being skilled at navigating both the material and emotional realms. Ruled by Saturn, the “timekeeper” of the zodiac, Capricorn is one of the most ambitious and persevering of all signs.

They are ambitious, determined, materialistic, perceptive, and disciplined. Because of their unwavering focus, Capricorns can sometimes be perceived as cold and unemotional. That doesn’t mean that Capricorns don’t know how to have fun. The sea goats tend to become increasingly youthful, optimistic, and playful as they age. Inside every Capricorn is a mischievous little troublemaker.

Aquarius Traits

On January 20, Aquarius season begins. Air sign Aquarius is represented by the water bearer, the mystical healer who bestows water, or life, upon the land. They are the last of the air signs, and of all the zodiac signs, Aquarius is the most innovative, progressive, rebellious, and humanitarian. Aquariuses are known to be intellectual and curious, often interested in conspiracy theories and out-of-this-world thoughts.

Aquarius is ruled by Uranus, the planet that governs innovation, technology, and surprising events. This perfectly complements Aquarius’ nontraditional nature. Aquarius also have a reputation for being cold and detached, sometimes so focused on their plans that they neglect their family and friends. Even though Aquarius can let the present slip away from them, their free-spirited and eccentric personalities make them so charismatic.
