Privacy and use
No name, account or email required. Birth details remain in page memory and are removed on clear or reload. They are not stored or added to URLs. Only language preference is saved locally. The site is funded by ads: pages load Adsterra ads in an isolated frame, and Adsterra and its partners may receive your IP and browser information and use cookies for ad delivery and measurement (privacy policy: https://adsterra.com/privacy-policy/). The ad frame cannot read this page, and we never provide birth details or charts to advertisers. Pages also load an Adsterra popunder (clicking the page may open an ad tab in the background, frequency-capped per visitor) and a Social Bar (a corner overlay). These two scripts run on the page itself: we do not deliberately provide birth details or charts to advertisers, but we cannot prevent a third-party script from reading the page; use your browser's ad blocking if this concerns you. Each move to another page is a full page load. Visitors in the EEA, UK or Switzerland must agree before ads load. No analytics or external AI requests are enabled. You can refuse ads with your browser's ad or cookie blocking; the tools keep working.
About this tool
A “sign” in Western astrology is the zodiac sector a body occupied at birth. Most people know their Sun sign; the Moon sign reflects emotions and security, Venus sign love and taste, Mars sign drive and desire. This page computes the four positions astronomically and describes each sign's element and mode.
With a second person it compares the Sun-sign aspect (conjunction, sextile, square, trine, opposition and so on), then the Moon signs and Venus–Mars interplay, giving a compatibility score with explanations. The ascendant and houses are not calculated since they need place and exact time; results are for entertainment.
FAQ
Why do Sun sign dates vary by year?
The moment the Sun enters each sign shifts slightly yearly; this page uses the actual ecliptic longitude so border birthdays are handled.
Is the Moon sign reliable?
The Moon changes sign about every 2.5 days; with no birth time noon is used and it may be off by one sign — a time makes it more reliable.
Why no ascendant?
It needs an exact time and birthplace coordinates, which this site does not collect.
Can astrology decide relationships?
No. It is cultural and entertainment reference, not scientific prediction.
