Gemini dates in astrology are from typically May 21 to June 20. If your birthday falls in this date range, you have a Gemini Sun sign. Although Gemini horoscope birth dates can change depending on the year, these are customarily the Gemini calendar dates.
For about 30 days each year, the Sun travels through the part of the zodiac occupied by Gemini. May 21-June 20 is typically the Gemini birth date range. Occasionally, the Gemini start date will be a day earlier on May 20, or the Gemini end date will fall a day later, on June 21.
Gemini is the third sign of the zodiac, which contains 12 signs in total. The Gemini star sign is an extroverted air sign (element) and an adaptable mutable sign (quality). As the only mutable air sign in the zodiac, Gemini people are quick-witted, versatile and known for changing their mind. Perhaps this is why Geminis are accused of double-talk. No surprise so many outspoken and controversial people have been born under the Gemini Sun sign: Kanye West, Joan Rivers and Donald Trump to name a few. As the zodiac sign that rules verbal communication, the Gemini star sign also features an unusual number of lyricists and hip-hop artists: Kanye, Tupac Shakur, Notorious B.I.G., Kendrick Lamar, Macklemore, Iggy Azalea and others. If you date a Gemini, prepare for some frustrating moments figuring out where you stand. This sign, while capable of commitment, can be whimsical and hard to pin down. Geminis can fall in and out of love at a moment’s notice.
The constellations have shifted. Is there a different Gemini birth date range now?
Periodically, astronomers will announce “breaking news” that horoscopes aren’t accurate because the constellations have shifted. Or they will announce is a 13th zodiac sign, citing the constellation Ophiucus and claiming that the horoscope dates for Gemini (and every other sign) have changed.
Here’s an interesting bit of clarification between astronomy and astrology. The actual constellations have shifted over the ages, but astrology follows a different system, which uses “artificial” constellations. Rather than following the movement of the visible stars, Western astrology is based on the apparent path of the Sun as seen from our vantage point on earth. Within that path, astrologers have carved out static zones, and we track the planetary movements against these. That is why Gemini dates remain the same even as the heavens keep shifting.
In second century Alexandria, the great mathematician and astronomer/astrologer Ptolemy created the Tropical Zodiac, which is a fixed system that is not affected by changes in the constellations or the Earth’s axis. Ptolemy used the same names for the zodiac signs as he did for the constellations, which is why there is confusion around the Gemini birth date range. The Tropical Zodiac is static and not affected by shifts in the Earth’s axis. It begins every year with the Aries pseudo-constellation, which is based on the position of the Sun at the spring equinox on March 21.
As the website Astrologer.com explains it:
Western astrology is based on the planets and their motion relative to our year (the Earth’s annual orbit of the Sun) and not on the distant stars. Before astrologers started to compile planetary tables, the backdrop of the distant visible ‘fixed’ stars proved to be most consistent system for measuring the positions of the ‘wandering stars’, known as the planets in our solar system. The 12 sign zodiac was defined by the stars within chosen constellations along the ecliptic (the apparent annual path of the Sun) in Mesopotamia at the end of the Iron Age (around 500 BC). Though the Babylonians used stars and constellations for measurement, they were also using zones which start from the position of the Sun at the March Equinox which was, is and will always be the start of the sign of Aries in the western system.
Vedic Astrology and Gemini star sign dates
Vedic astrology, also known as Jyotisha, is the traditional Hindu astrology system. It is based on the Sidereal zodiac, or Nirayana, which is an imaginary 360-degree “belt” of zodiac signs divided into 12 equal sectors. However, Vedic astrology is different from Western astrology in that it measures the fixed zodiac, rather than the moving zodiac. So in Vedic astrology, the Gemini dates would be June 15-July 14. Go figure!
