About Astrology Tools

Astrology isn't a science, and nothing here claims otherwise — but the calculations behind a birth chart, a moon phase, or a numerology number are real arithmetic on real dates and positions, and getting that arithmetic right is exactly the kind of mechanical task a browser is good at. These tools compute your actual sun, moon, and rising signs from the date, time, and location you enter, using standard astronomical and calendrical methods, rather than guessing or returning a generic result.

What you do with the output is up to you. Some people use a birth chart or a compatibility score for genuine self-reflection or as a conversation starter with a partner; others just enjoy seeing where the planets were the day they were born. Either way, the honest description of what's happening is 'a calculator applied to astrology's traditional rules,' not a prediction about your life — and every result here comes from that same calculator, computed the same way for everyone.

Because everything runs client-side, your birth date, time, and location never leave your browser. That matters more than it might first seem: a birth chart is a more personal piece of information than most people treat it as, and there's no reason it needs to touch a server to be calculated.

Astrology Tools — Frequently Asked Questions

Are these tools scientifically accurate predictions?

No — astrology itself has no scientific basis for predicting personality or events, and these tools don't claim otherwise. What they do accurately compute is the underlying astronomical and calendrical data astrology is traditionally built on: where the sun, moon, and planets were on a given date, or what a numerology calculation returns for a given birth date. The math is real; what it means is a matter of personal belief, not fact.

Is my birth date and time sent to a server?

No. Every calculation runs locally in your browser using standard formulas. Your birth date, time, and location are used only to compute the result on your own device and are never transmitted anywhere.

Why do I need my exact birth time for a birth chart?

Your sun sign only depends on the date, but your rising sign (and the house positions in a full birth chart) depend on the exact time and location, since the sky's apparent position changes about one degree every four minutes as the Earth rotates. Without a precise birth time, a rising sign or house placement can't be calculated accurately — if you don't know yours, a birth certificate or hospital record is usually the most reliable source.

Do the compatibility calculators use real astrological methods?

They compare the traditional sign-to-sign and planetary relationships astrology uses for compatibility (synastry), rather than a random or arbitrary score. As with the rest of this category, that means the comparison follows astrology's own established rules — it isn't a claim that the result predicts how well a relationship will actually work.
