What is a rising sign?

The Ascendant is not a planet. It is a point on the ecliptic, the path the Sun appears to travel through the year, defined by where that path meets the eastern horizon at your birth latitude and longitude. Because the Earth turns once a day, the whole zodiac passes over the horizon in 24 hours. That is why the Ascendant changes sign roughly every two hours.

This is also why the birth time cannot be guessed. A birth certificate time of 7:15 and a remembered time of 7:30 can put the Ascendant in different signs, and that changes every house cusp in the chart. If the time is unknown, this site gives a noon chart with no rising sign rather than inventing one.

The rising sign describes your manner, your physical style and the way you enter a room. It is the interface between you and the world: the tone you use before you have decided what to say. People often recognize themselves in it quickly, sometimes more quickly than in their Sun sign.

It also sets the chart ruler. If you have a Libra Ascendant, Venus rules the chart and its sign, house and aspects become a thread through the whole reading. The same planet can be quiet in one chart and central in another simply because of the rising sign.

Treat the rising sign as one layer among several. The Sun sign is the identity you grow into, the Moon sign is the need you return to, and the Ascendant is the door. A person with a Scorpio Sun, a Gemini Moon and a Sagittarius Ascendant is not three separate people; they are one person with a private depth, a quick mind and a sociable entrance.

The most useful next step is to calculate the exact degree and look at which house it falls in. A rising sign at 29 degrees is about to hand over to the next sign, and people born in that window often feel the description of both signs.
