Astrology compatibility calculator FAQ
Answers about our free calculator, what you get without Pro, and how chart matching differs from sun-sign tools. Open the astrology compatibility calculator.
What is an astrology compatibility calculator?
It compares two people’s birth details (date, place, and optional time) to produce a relationship reading grounded in both charts — not just sun-sign matching. You get a compatibility score, red and green flags, deep topics, and forecasts.
How is this different from zodiac compatibility?
Zodiac compatibility usually compares two sun signs (for example Aries and Leo). Our astrology compatibility calculator uses full birth charts (synastry-style) so you see how the charts interact across love, communication, and tension — deeper than a sign pair page.
Is the astrology compatibility calculator free?
Yes. You can run a reading for free and see the summary plus the first Deep topic. Pro unlocks remaining Deep chapters and timed forecasts for the pair.
Do I need exact birth times?
Birth time is optional but helpful. Without it, planetary signs and many aspects still work; rising sign and some house-based detail are less precise.
Can I check friendship, family, or work compatibility?
Yes. Choose a relationship lens — Romantic, Friendship, Family, or Work — before you reveal the reading so the report focuses on the right dynamic.
Where can I browse sun-sign and celebrity compatibility?
Use our zodiac pair guides and celebrity birth chart pages for quick sun-sign style reads, then return to the free astrology compatibility calculator for a personalised two-chart report.
