Astrology calculators
Real ephemeris math, not a lookup table. The same engine that powers our birth charts.
Every calculator here runs on the Swiss Ephemeris, the astronomical data professional astrologers use. Where your data is not enough for an exact answer, we say so instead of printing a confident guess: a rising sign without a birth time is not a rounding error, it is a coin flip between twelve signs.

Questions about the calculators
Are these calculators free?
Yes, all of them, with no sign-up and no card. They run pure astronomy on our server, so there is nothing to unlock.
How accurate are the results?
The positions come from the Swiss Ephemeris, the same high precision data professional astrologers rely on. Accuracy is limited only by the birth data you enter, and each calculator tells you what it needs.
Why do you ask for a city and not a country?
The city gives us coordinates and, more importantly, the historical time zone with its daylight saving rules. Without it your birth moment can be off by hours, which is enough to change the Ascendant and sometimes the Moon.
What if I do not know my birth time?
The Moon sign and the Saturn return still work, and we show you how much the answer can drift. The rising sign genuinely cannot be computed, so we refuse rather than invent it.
Do you store what I enter?
The calculators do not create an account or a saved profile. The data goes to the server, gets computed and comes back.
