How Often Does My Ascendant Change?
The ascendant, or rising sign, is a crucial component of your astrological profile, representing the sign that was rising on the eastern horizon at the exact moment of your birth. Unlike your sun sign, which remains constant throughout your life, the ascendant is highly sensitive to the time and place of your birth. But how often does this pivotal element of your natal chart change?
What Is the Ascendant?
The ascendant is the zodiac sign that was ascending on the eastern horizon at the time of your birth. It changes approximately every two hours, making it one of the most dynamic aspects of your natal chart. This rapid change is why knowing your exact birth time is essential for accurate astrological readings.
How Is the Ascendant Calculated?
To determine your ascendant, astrologers use the date, exact time, and location of your birth. These details are input into an astrological chart, which maps the positions of the planets and signs at that moment. The ascendant is found at the cusp of the first house in your natal chart.
Why Does the Ascendant Change Every Two Hours?
The Earth rotates on its axis once every 24 hours, causing the zodiac signs to rise and set. Each sign occupies the horizon for about two hours, resulting in the ascendant changing approximately 12 times a day. This frequent change is why two people born on the same day but at different times or locations can have different ascendants.
How Does the Ascendant Influence Your Personality?
Your ascendant influences your outer personality, appearance, and the first impression you make on others. It acts as a mask you wear when meeting new people and navigating new situations.
