How these calculators work

Each calculator computes the real position of the Sun, Moon, Venus or chart angle at your birth moment, using the standard astronomical algorithms published by Jean Meeus and the time zone rules for your birth city - the same kind of maths professional astrology software uses, running entirely on your device. Where a result depends on information you may not have (like an exact birth time), the calculator tells you what can and cannot be known, instead of guessing quietly.

Frequently asked questions

What is the difference between a sun sign, moon sign and rising sign?

Your sun sign (from your birth date) is your core identity; your moon sign (date, ideally time) is your emotional nature; your rising sign (date, exact time and place) is your outer style and first impression. Together they are called the Big Three, and the combined calculator on this page finds all three at once.

Do these calculators store my birth details?

No. Every calculation runs in your own browser using astronomical formulas - your birth date, time and place never leave your device, and there is no account, no upload and no tracking of the details you enter.

Which calculator should I start with?

Start with the Sun, Moon & Rising calculator for the Big Three summary. Then go deeper: Venus for love style, the North Node for life direction, Chiron for your wound-and-gift theme, and the Part of Fortune for where ease gathers.

Are these calculators accurate?

They use the same standard astronomical algorithms as professional software (Meeus) and agree with ephemeris positions to within a fraction of a degree for the Sun and Moon. When a birth falls in the short window of a sign change, the calculators say so and explain what extra information settles it, instead of guessing.

ToolFoxHub astrology calculators are for entertainment and self-reflection. Astrology is a symbolic tradition, not a science, and these readings are traditional interpretations, not facts or advice. Positions use the tropical zodiac and standard astronomical formulas (Jean Meeus) computed in your browser - nothing you enter leaves your device. Results agree with professional ephemerides for the great majority of births; if you were born in the short window when a body was changing sign, your exact birth time and place decide the answer, and the calculator says so when that is the case.
