What “retrograde” means here
A planet is retrograde when its ecliptic longitude, seen from the Earth, is decreasing: it appears to move backwards against the stars. A station is the moment it appears to stop before changing direction. The Sun and the Moon never turn retrograde. Each date above is a station computed to the minute.
What these dates are worth
Every time on this page is computed by the engine that casts the charts, not copied from a table. All times are Universal Time (UT), so a date can fall a day either side of your own clock: add your time zone's offset to get local time. The Moon is checked against NASA and JPL values and the planets against published station and ingress dates; the table of what Umbriel checks, and how close it comes is public. Umbriel is for reflection and self-understanding, not prediction.
