Frequently asked questions

What does Birth Chart Calculator do?

Get your free birth chart explained in plain language: your Sun, Moon and Ascendant, planets, houses and aspects, from your birth date, time and city. You also see what dominates your chart, the strongest links between your planets and what each house covers, with the chart wheel and the exact natal chart data one click away. Summer time is handled for you, and your details stay in your browser.

When would I actually use this?

Looking up what a birth date or a name is said to mean: a sun sign, the rest of a birth chart, a life-path number, or the same for someone else before a conversation about it.

What is the most common mistake?

Taking a sun sign as the whole chart. Someone born a day either side of a cusp changes sign depending on the year and the time of day, and the moon and rising signs move much faster than the sun does — a birth time is what separates a chart from a guess.

How is Birth Chart Calculator different from Angel Number Calculator?

They sit next to each other but answer different questions. Angel Number Calculator: interpret a recurring number you keep seeing (like 111, 444 or 1234) or reduce your birth date, and read its spiritual meaning. Pick whichever matches what you're starting from — both are free.

Is there a tool for the next step?

Astrocartography Map is the closest one after this: Free astrocartography map: find the places where love, career or feeling at home are highlighted for you, based on your birth date, time and place. Cities near your lines are grouped by area of life, the map draws the lines of all ten bodies with a legend, and you can check any city. Distances are in kilometres, and summer time at your birth is taken into account.

What else is worth having open alongside it?

Astrological Element Balance Calculator and Astrological Modality Balance Calculator — they come up in the same task often enough to be worth a second tab.

Where do the figures come from?

The positions are computed from real ephemeris arithmetic, not from a fixed table of dates, so a cusp birthday lands on the right side of the boundary for its own year. What those positions are taken to mean is tradition, not measurement, and the tools present it as such.
