How it works
Three facts
Your birth date, your birth time if you know it, and the town you were born in. That is all a chart is made from, and it is all we ask for.
Worked out on the spot
The positions are calculated in your browser from published planetary data, the same kind of tables the big astrology sites use. We show the settings and the time offset used, so you can check any line of it.
Read in plain words
Your Sun, Moon and rising sign, explained the way you would explain them to a friend. Save the chart in your browser, or share it with a link. Still no account.
Why you can check us
We show our working.
Every chart prints the time zone offset it used. If your birth time fell in the hour the clocks jumped, the chart says so. If you were born so far north that the usual house system cannot be drawn, the chart says that too, and shows the fallback it used instead of quietly relabelling it.
Our numbers are tested against NASA JPL reference values, and the test results are published, not promised. Read how we calculate.
