An astrological chart is a symbolic representation of the position of the planets, the sun, and the moon at the moment of a person’s birth. To create a chart, you’ll first need your birth date, time, and place. Then the easiest way to generate a chart is by using a website that takes your information and does the math for you. Once you’ve got your chart, you can read it for lots of different ideas about all aspects of your life. Keep in mind that astrology is an art, not a science. Take the parts that hit home for you, and leave the rest.
