Cast a Star Chart
Real positional astronomy running in your browser. Sun and Moon from Meeus, planets from JPL Keplerian elements, Ascendant and Midheaven from true sidereal time. Search any city in the world — the timezone is handled automatically.
Search for any city worldwide — we automatically look up the coordinates and compute the correct historical timezone and daylight-saving offset for your birth date. No manual UTC guessing required.
Members can save charts to their account and revisit them any time from the dashboard.
Today's transit wheel
The same renderer, fed the current moment instead of a birth moment. Members get an alert when a slow planet makes an exact aspect to something in their own chart.
Built on the same engine
Synastry
Two members opt in; we overlay both wheels and score the cross-aspects.
Solar Return
Your chart for the exact moment the Sun returns to its natal degree each year.
Saturn Return Clock
A countdown to the transit everyone in their late twenties is already talking about.
Void-of-Course Moon
Daily windows when the Moon makes no aspects — the classic "don't start anything" hours.
