Gemini Dates of Birth

Your Zodiac sign (also called sun sign or star sign) is decided by the position of the sun at the moment of your birth, as seen from Earth. The sun takes a year to travel through the twelve Zodiac signs, but it's not exactly a year of 365 days. The time it takes is closer to 365.25 days. That's why we have leap years.

     Every fourth year we add a day to the calendar, the 29th of February, making that year 366 days. Actually, there's an additional rule, to make it more precise with the actual movement of earth and the sun: the starting year of a new century is not a leap year, unless it's evenly divisible by 400. So, 1900 was not a leap year, but 2000 was.

     The leap years make the dates of each Zodiac sign change slightly. Normally, Gemini starts on May 21 and ends on June 20, but that's just the mean. In reality it changes slightly in a four year period from one leap year to the next.

     Here are the leap years of the last century:

1904 1908 1912 1916 1920

1924 1928 1932 1936 1940

1944 1948 1952 1956 1960

1964 1968 1972 1976 1980

1984 1988 1992 1996 2000

2004 2008 2012

     If you were born on the 21st of May or the 21st of June, you have to check if you're really a Gemini or not. It never differs more than a day in each direction. The start of Gemini must be within the 20th to 21st of May, and the end of it is mostly on the 21st of June. People born on other dates need not be concerned.

Cusp or not

If you were born on May 20th or 21st, your sun may be on the very cusp (the starting point) of Gemini, or right by the end of Taurus. If you were born on the 21st of June, your sun might be at the very end of Gemini or at the cusp of Cancer. You need to check your exact horoscope, because on those dates it depends on what time of day you were born - and in what place.

     It's particularly important with this check If you were born far away from Greenwich, England, since that's the base for the dates given for Gemini.

     You can get your exact horoscope computed for free on several websites. Go here to find instructions and links to them: Your own horoscope.

     Now, If you were born on May 21st at a time when your sun is at the very end of Taurus, you probably have a mixture of Taurus and Gemini in your character. It's a Taurus inclined to be more of a Gemini. If your sun is at the very start (cusp) of Gemini, though, you're definitely a Gemini - and a firm one at that.

     If your sun is at the very end of Gemini, you may show personality traits of both Gemini and Cancer, but If you were born at the very start of Cancer, no matter how early in it, you're most definitely a Cancer.

     That's because each sign is the most powerful at its beginning, its cusp.

Decans

The strongest is not equal to the most typical, though. A Zodiac sign is its most typical at the part of it (decan) corresponding to its quality: cardinal, fixed or mutable. Each Zodiac sign is one of the four elements fire, earth, air, and water. It's also one of the three qualities. So, four elements and three qualities make twelve possible combinations.

     Gemini is the mutable air sign. That means its most typical part is the last one - the ten degrees making its third decan, 20°-30° Gemini. That corresponds approximately to the dates June 11-21. If your birth date is within this range, you're likely to be a very typical Gemini.

     If you were born on late May, the 21st to 31st, you're still a Gemini, but with character traits comparable to those of Libra (the cardinal air sign). If you were born on June 1st to 10th, you have some tendencies similar to those of Aquarius (the fixed air sign).

     Astrology is rather complicated, when dealt with seriously.

     But the most important thing to decide is what sign you are. So, If you were born on May 20th-21st or June 21st, please have your correct horoscope calculated to be sure of your sun sign.
