Agrippa’s Moon Mansions Calendar 2027

About this book

In Book II, chapter 33, Agrippa divides the zodiac into 28 equal mansions of 12° 51′ 26″ and gives each a name and an effect: for journeys, for love and friendship, for harvests, for finding treasure, for strengthening buildings, and some for discord and sieges. The calendar uses that table in our own translation from the Latin, and works out where the Moon stands on every day of 2027.

Calculated and checked. The Moon's position follows the standard method of Jean Meeus (Astronomical Algorithms), counted from the vernal point as Agrippa describes. We compared it with NASA JPL Horizons (twelve test dates, largest difference under 8 arc-seconds) and with the U.S. Naval Observatory phase table (all 49 listed phases of 2027 match to within one minute). Times are in UTC, with a note on converting to your time zone.
