Frequently Asked Questions
What is a birth chart and how does AstroMood create one?
A birth chart (also called a natal chart) is a map of the sky at the exact moment you were born. It shows the positions of the Sun, Moon, and planets across the 12 zodiac signs and 12 houses. AstroMood uses Swiss Ephemeris — the same professional-grade astronomical engine used by leading astrologers — to calculate your chart with arc-second precision. You just need your birth date, time, and place.
How accurate are AstroMood's astrological calculations?
AstroMood uses Swiss Ephemeris, which provides planetary positions accurate to fractions of an arc second. This is the same calculation engine used by professional astrologers and astronomical research institutions worldwide. Combined with our database of 147,000+ cities with precise coordinates and timezone data, your chart reflects the exact sky at your moment of birth.
What is synastry and how does compatibility analysis work?
Synastry is the astrological technique of comparing two birth charts to understand relationship dynamics. AstroMood overlays both charts and analyzes cross-aspects — how one person's planets interact with the other's. This reveals areas of attraction, tension, growth, and harmony between two people, whether for romantic relationships, friendships, or business partnerships.
What are planetary transits and why do they matter?
Planetary transits are the current movements of planets through the zodiac. When a transiting planet forms an aspect to a planet in your natal chart, it activates that area of your life. For example, Jupiter transiting your 7th house can bring new partnerships, while Saturn transiting your 10th house may restructure your career. AstroMood tracks these transits in real-time against your birth chart.
Is AstroMood free to use?
Yes, AstroMood is free to use. You can create birth charts, view interpretations, read our educational library of 400+ pages covering planets in signs, transits, and compatibility, and analyze zodiac compatibility — all at no cost. Create an account to save your charts and access additional features like transit tracking and chart sharing.
