Planetary cycles

The transiting planet is the weather. The natal planet is the landscape.
A cycle begins at conjunction and unfolds through test, flow, mirror, integration, consciousness crisis and renewal. This section keeps the interpretation fixed and simple so you can see the larger pattern clearly.
This section can use the current default ephemeris or a separate long-range ephemeris saved only in this browser. It does not replace or change the GitHub/default ephemeris.

Local long-range ephemeris

Upload 50, 100, or 200 years here when you need longer cycles. It stays in this browser only.

No cycle built yet.

Individual transit calendar

Choose one or more transiting planets, a date or date range, and the aspects/orb. The cleanest long-range option is Chronological timeline with Summary only or Major events only.

How this section works plain English guide
Chronological timeline
The app now uses this automatically. It organises results by month, year or decade depending on the size of the date range.
Summary only
Shows the planet moving through signs and natal houses. This is the big picture story.
Major events only
Shows sign changes, house changes, retrograde periods, retrograde/direct stations, exact aspects and tight one degree windows.
Full daily details
Shows daily positions and daily aspects. Each day is automatically grouped by planet. Use this for short ranges only because long ranges create a lot of data.
Orb
The orb decides how close an aspect must be to count. A smaller orb is stricter. A larger orb shows wider influence windows.
Transiting planets / points selection 0 selected
What this means
These are the moving planets or points in the sky. The app will follow the ones you select across the date range and compare them to the natal profile.
Aspects to include 0 selected
What this means
Aspects are the angular relationships between a moving planet and a natal point. Select the aspect types you want included in the report.

Main ephemeris CSV

The app loads the shared default ephemeris automatically from GitHub/Cloudflare and caches it locally. Uploading here changes the main app ephemeris only, as before.

Local Ephemeris Library

Use this for long-range research.
Upload 50, 100, or 200 year ephemeris files here, give each one a nickname, and then choose it from the Individual Transit Calendar or Planetary Cycles source dropdown. The default ephemeris is still pulled from GitHub/Cloudflare separately.
No local ephemerides saved yet.
