The astronomy
Earth and the other planets travel around the Sun at different speeds. From our moving viewpoint, a planet can appear to travel backward through the zodiac for a while. It continues along its orbit around the Sun.
A station is the turning point where the rate of change in a planet’s geocentric ecliptic longitude passes through zero. A retrograde station starts the backward interval; a direct station ends it.
Each planet has its own cycle relative to Earth. Several cycles can overlap, and the more distant planets spend months in apparent retrograde motion. The count above describes those overlapping intervals.
A station happens at one instant worldwide. It can fall on different calendar dates in New York, Los Angeles and UTC. The time-zone selector converts every event using the offset in effect on that date, including daylight saving time.
Positions use the tropical zodiac and geocentric apparent ecliptic longitude calculated with Astronomy Engine 2.1.19. Stations are the same prepared events used by the Zodiaris Sky calendar. They are found from a sign change in longitude speed, sampled symmetrically one hour before and after the instant, with the time search narrowed to one second.
Shadow crossings use those station longitudes. Times are displayed to the minute; this display precision is not a claim of one-minute agreement with every ephemeris. Small differences can arise from the astronomical model, coordinate conventions and rounding.
