Frequently Asked Questions
What is a natal birth chart in Western astrology?
A natal birth chart (also called a horoscope or nativity) is a map of where all the planets were at the exact moment and location of your birth. It shows each planet in a zodiac sign and house, the ascendant (rising sign), midheaven (MC), and angular relationships (aspects) between planets. The birth chart is the foundation of personal astrology.
What is the ascendant (rising sign) and why is it important?
The ascendant (or rising sign) is the zodiac sign that was rising on the eastern horizon at your birth moment. It determines the 1st house cusp and the entire house structure of your chart. The ascendant shapes your outward personality, physical appearance, and how others perceive you. It changes approximately every 2 hours, which is why accurate birth time is essential.
What is the Placidus house system?
Placidus is the most widely used house system in Western astrology. It divides the chart based on the time it takes each degree of the ecliptic to rise from the nadir to the ascendant. This creates unequal house sizes that vary by latitude. Each house governs different life areas: 1st house (self), 7th house (relationships), 10th house (career), etc.
