Ascendant is the sign that was rising on the eastern horizon at the moment of your birth. It is your mask , how you enter situations and how others see you first.

Descendant is always exactly opposite (Ascendant +180°). It shows who you attract and what you seek in relationships , a partner who complements you.

The mockup uses a simplified calculation. In production it will be wired to the Swiss Ephemeris library (precision to seconds).
