Frequently Asked Questions
What are the Big Three in astrology?
The Sun sign (core identity), Moon sign (emotional nature), and Rising/Ascendant sign (outward personality) — together they form the most-read part of a birth chart.
Why do you need my birth time?
The Rising sign changes roughly every two hours as the Earth rotates, so an accurate birth time is needed to calculate it.
Why does birthplace matter?
The Ascendant is the zodiac sign rising on the eastern horizon at your birth moment — which depends on both the time and the geographic location.
Is astrology scientifically proven?
No. Astrology is not supported by scientific evidence — this tool is for entertainment and curiosity.
Is the calculator free?
Yes, free with no signup.
