Horoscope sign dates are easy to find. Your sign is determined by the date of your birth.
How Dates Were Assigned To Signs
You might wonder how these dates were assigned to each sign. It's fairly simple. It all began with the Spring Equinox. Since Aries is the first zodiac sign, it was assigned to this beginning date of March 21.
Born On The Cusp
You may have heard people say they were born on the cusp of Libra or another sign and wondered what they meant. To be born on the cusp means your birthday falls on the first day or the last day of a zodiac sign. Many times a person displays traits of both signs. For example, if a person was born on April 19, it might be difficult to determine if that person is really a Taurus or an Aries.
If you were born on a cusp, an astrologer will need to know the latitude and longitude of the place where you were born as well as your exact time of birth. These pieces of information will allow the astrologer to accurately calculate your sun sign.
Sun Signs: Conflicting Range of Dates
One thing you may have noticed is that sometimes when you look up your sun sign, you find a discrepancy in the range of dates used for your sign. These can differ from one or two days depending on the source you are using. This can create confusion and some people might decide they aren't a particular zodiac sign after all.
Why Sign Dates Can Differ
The zodiac is comprised of twelve signs, and each sign is assigned thirty degrees within a three hundred and sixty degree circle. The sun moves through each sign's constellation. When you're born, where the sun is during that moment of birth determines which one is your sun sign.
A range of dates for each sun sign is determined by the date the sun enters a zodiac sign's constellation and the date it leaves.
The reason the range of dates can change is because the calendar cycle changes due to leap years. Many astrologers use the current year's dates while others prefer to stick with the original fixed dates assigned to specific zodiac signs. Just because the dates are different from the ones you use doesn't make your sun sign invalid. You need to decide which method of determining your sun sign you wish to use and then stick with it.
Regardless what the current range of dates are, the only important thing is what the range was at the time of your birth. That determines your true sun sign. To find this out, you can use an ephemeris to reveal the beginning and ending dates for each sign. An ephemeris (derived from Greek word ephemeros which means daily) is a table that lists the positions of the stars and planets at any given moment in time. With astrology computer programs wide-spread, these have been pared down to simply typing in a date and receiving your sun sign.
