Birth Chart Calculator

If you are unfamiliar with your birth chart, you can enter your birth data here and have one generated for you. This birth chart calculator, supported by astro-charts.com,  defaults to a house system called Placidius which is a quadrant based house system that divides your chart into houses based the location of the 4 angles and the amount of time the Sun spent in each area of the sky on the day you were born. The house descriptions you’ll find on this website, however, were written with the use of the Whole Sign house system in mind. While the house meanings can be applied to any house system, planets in your birth chart may have a different location by house in the Placidius house system then in the Whole Sign house system. If you want to know the which Whole Sign house the planets in your chart are located, you can simply ignore the doted lines marking the houses in the birth chart you calculate here, and and count the number of signs from the sign of your ascendant instead.
