How to use this calendar

The table lists complete station-to-station intervals overlapping this year. A start in the previous year and an end in the following year keep their original years. It includes Mercury through Pluto and Chiron; the Sun and Moon do not turn retrograde. These are apparent motions from Earth, not reversals of planetary orbits.

Time and precision

Event times use UTC and are displayed to the minute. Daily ephemeris rows use 00:00 UTC and are a different kind of observation. Your local date may differ; convert with the actual timezone and daylight-saving rules.

Calculations and interpretation

Events come from AskNeyora’s Swiss Ephemeris calculations using the tropical zodiac and geocentric positions. A calculated event date does not establish a particular event in an individual’s life.
