Gemini Dates of Birth
Are you really a Gemini?
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:
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
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.

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.
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).
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.
