The term “Sun sign” means that, if you are, for example, a Gemini, the Sun was in the zone of the zodiac called Gemini when you were born, approximately between May 21st and June 21st, inclusive. You’ll find that the dates covering the Sun sign periods are slightly different, depending on which astrology book you read. Most astrologers don’t wish to confuse the layman with the information that the Sun changes signs in the morning, afternoon or evening of a particular day. It’s all very nice and neat and easy to pretend each new sign begins precisely at midnight. But it doesn’t. For example, except for leap year variations, the Sun, for the last several decades as well as at the present, both leaves Aries and enters Taurus sometime on April 20th. It’s important to know that April 20th contains both signs. Otherwise, you might go around all your life thinking you’re a Taurus when you’re really an Aries. Remember that if you were born on the first or the last day of any of the Sun sign periods listed in this book, you’ll have to know the exact time and the longitude and latitude of your birth to judge whether or not the Sun had changed signs by that hour.
