Why this site exists
Many calculators ask for a birth time you may not know, then quietly substitute noon. We wanted a clearer answer. Here, an unknown time produces a full-day check, two candidates when needed and no invented Rising sign. The core calculation runs in your own browser.
What we offer
Explore Moon, Sun, Rising, Venus, Mars and Mercury placements, a birth Moon phase and a simple Moon-sign relationship comparison. Read the twelve Moon profiles and practical guides. The site currently publishes in English and all calculators are free. No account or purchase is required.
Our sources
Astronomical positions come from the MIT-licensed Astronomy Engine project. Time conversion uses Luxon and the IANA timezone data available in your browser. Place data is adapted from GeoNames cities500, admin1CodesASCII and countryInfo under CC BY 4.0. Interpretation is editorial material, separate from the astronomical calculation.
