What is the Retrograde Calendar and how does it work?
The Retrograde Calendar is a precision horoscope and forecasting calculator that reads your birth data, computes exact planetary longitudes on our server ephemeris, and translates the math to see retrograde dates and the days around them. Not a static date-range lookup table that guesses your sign on cusp days, but a live astronomical solver powered by VSOP87 and J2000 orbital elements. You enter your birth details once, and the server returns a cryptographic verification seal with a plain-English breakdown.
