Aquarius Dates of Birth
The Zodiacal Sign of Aquarius commences on January 21st, but for seven days, being overlapped by the "cusp" of the previous sign, it does not come into full power until on or about January 28th. From this date onward it can not take its full strength until February 19th and is then for seven days gradually losing its strength on account of becoming overlapped by the "cusp" of the incoming sign Pisces.
Often simple and unassuming, the Aquarian goes about accomplishing goals in a quiet, often unorthodox ways. Although their methods may be unorthodox, the results for achievement are surprisingly effective. Aquarian’s will take up any cause, and are humanitarians of the zodiac. They are honest, loyal and highly intelligent. They are also easy going and make natural friendships. If not kept in check, the Aquarian can be prone to sloth and laziness. However, they know this about themselves, and try their best to motivate themselves to action. They are also prone to philosophical thoughts, and are often quite artistic and poetic.
In astrology, your Aquarius 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, Aquarius starts on January 21 and ends on February 19, 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 21th of January or the 19th of February, you have to check if you’re really an Aquarius or not. It never differs more than a day in each direction. The start of Aquarius is almost always on the 21th of January, and the end of it on the 18th or 19th of February. People born on other dates need not be concerned.
