Retrograde Calendar
About Retrograde Calendar
Station times, degrees, durations, and shadow periods for every retrograde of the year — computed astronomy, not folklore.
No planet ever backs up; the loop is a trick of parallax as Earth laps a slower world or is lapped by a faster one. The tradition reads it accordingly. A changes a planet's gear, not its meaning; matters under its sponsorship come round again for review, revision, repair. The days that carry real weight are the , when a planet stands still to turn. Mark those dates, not the whole stretch.

The slow planets
Jupiter outward, a planet spends four to five months of every year retrograde; that is ordinary weather, not an event. The slower the planet, the longer the spell and the less it asks of any single day. Mark the stations; the rest is season.

All times Universal Time (UT), from the same engine as the sky. Spells that open or close beyond the calendar year are listed with their own year on the date; the window belongs to both years and appears on both pages. On doctrine: a retrograde conditions a planet's expression; it does not doom it. The working tradition keeps no list of forbidden days, a spell that repeats a is one process rather than three misfortunes, and the shadow is context, not an extension of the sentence. The stations are the moments that matter; what a planet touches while standing still, it means.
