What is an ascendant (rising sign)?
The ascendant (Latin: ascendens — “rising”) is the zodiac sign that rises on the eastern horizon at the moment of your birth. It is one of the three most important elements of a natal chart, alongside your Sun sign and Moon sign.
While the Sun sign describes your inner essence and the Moon sign your emotions, the ascendant determines how others perceive you. It’s your “social mask” — the first impression you make, your style of being and the way you approach new situations.
The ascendant changes approximately every 2 hours, which is why an exact birth time is essential for its calculation. Our calculator uses Swiss Ephemeris — a professional astronomical library used by the best astrological software worldwide.
