An astrological birth chart uses the exact date, time, and location of your birth to re-create a snapshot of the sky at your precise moment of arrival. Within the folds of this circular map, you’ll find all the planets and celestial objects tracked in astrology, along with the zodiac signs they were occupying.
As your eyes move across the diagram, you may notice that the chart is divided into different sections — 12, to be exact. These pie slices are referred to as “houses.” Avoid the common misstep of conflating houses with zodiac signs (yes, there are 12, but it’s not the same thing). The houses are a visual expression of Earth’s 24-hour rotation around its axis, which means that each House represents approximately two hours of time.
