Sky Chart

Build the sky intentionally

Choose a guided path, then enter only the skies that path needs. Advanced mode keeps the direct editor available when you already know what you want.

Step 1

Where and When

Here and Now

Use the current place and time, or choose another where and when.

First sky: empty

Step 2

Optional comparison

Compare to another sky

After the first sky is created, add a second sky only when the reading calls for it.

When

Where

Calculates geocentric ecliptic longitude for planets, plus Rising, Midheaven, and the selected house system from the chosen date, time, and location. Coordinates can resolve location label and IANA time zone; calculated date/time is interpreted in that coordinate time zone when available. Saved/imported metadata can restore date, time, and location; no private birth data is hard-coded.
