Rising Sign Calculation

In Western Astrology, Ascendant is the sign that rises on the eastern horizon at the moment of one's birth. This sign can be seen on the east horizon on the natal chart. The ascendant sign is also the ruler of the 1st house in astrology.

The harmony of time and planets at the moment of birth and the planets in retrograde shapes this chart. The rising sign also determines the placement of houses in natal charts. Because the rising sign is related to the birth time and place, it provides the most important and accurate information.
