Gemini Dates of Birth
The Zodiacal Sign of Gemini - The Twins commences on May 22st, but for seven days it does, not come into its full power until on or about May 28th. From this date onwards it is in full strength until June 20th, and is then for seven days, gradually losing strength on account of becoming overlapped by the "cusp" of the incoming sign Cancer.
Flexibility, balance and adaptability are the keywords for the Gemini. They are quick to grasp the meaning of a situation and act on it, often with positive effects. They tend to have a duality to their nature, and can sometimes be tough to predict how they will react. They can turn from hot to cold and may be prone to noticeable mood swings. However, they are generous signs with tendencies of being affectionate, and imaginative. They also inspire others easily as they seem to naturally motivate themselves - their charisma and accomplishments are infectious. Geminians are very supportive, and are especially good at promotions, sales, and driving hard bargains.
In astrology, your Gemini 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 22 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.
If you were born on the 22nd 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.
