Calculators

What is my sign?

Your Sun sign is one placement out of about forty. These twenty calculators answer one question each, from your birth date, time and place, computed from the Swiss Ephemeris rather than looked up in a table.

The six personal ones

These move quickly enough to be genuinely yours rather than shared with everybody born the same year. They are the ones worth knowing first.

The two that set the terms

Jupiter and Saturn move slowly enough to be shared with an age group and quickly enough to still be yours. The tradition reads them as a pair: where it is easy and where it is not.

The three you share with your generation

Uranus, Neptune and Pluto take between seven and twenty one years to cross a sign. Everybody your age has the same one, so these describe a cohort rather than a person, and the dates are given so you can see that for yourself.

The lunar nodes

Two ends of one axis, always exactly opposite. The tradition reads the South Node as what is already easy and the North Node as the direction that is not.

The other points

Chiron, Lilith, the Part of Fortune and the four main asteroids. Later additions to the tradition, all of them, and read as specific rather than central.

Why the birth time matters more for some

It comes down to speed. The Sun takes a month to cross a sign, so a date is almost always enough. The Moon takes two and a half days, which is fast enough that a date alone can leave the answer genuinely ambiguous. The rising sign changes every two hours, so it cannot be calculated at all without a time, and any site that offers you one anyway is guessing.

Where no time is given, these calculators assume midday and say so on the result rather than quietly presenting a coin toss as an answer.

Or do the whole thing at once

The full birth chart computes all twenty of these plus the houses and the aspects between them, from the same three details, and shows how they sit together rather than one at a time. It is free and nothing needs to be signed up for.
