In astrology, the planets only tell part of the story. In your natal chart, or in a transit report, the placement of the planets tells how they are likely to influence things. The astrological houses tell where these influences are likely to occur.
The zodiac is made up of 360°. There are 12 different houses, and they each represent an area of your life — such as personality, income, creativity or career. While each Sun sign is always 30°, the size of the houses can differ, depending on what method is used to calculate them, your place of birth, and what time of day you were born. This is why the time of your birth is so essential for a comprehensive astrology interpretation.
