Stations from the NASA JPL DE440 ephemeris. Swiss Ephemeris agrees on every Neptune station 1900–2050: median under a minute, largest 1.8 minutes. Near a station Neptune barely moves, so almanacs differ by minutes. Local times: IANA time zones, to the minute.

Both dates are computed from the planet’s apparent motion, not taken from a
table. A retrograde begins the moment its daily movement against the stars turns
negative, and that moment is findable to the hour.
Computed for 1909
Neptune through the zodiac in 1909
Every sign Neptune occupies during 1909, with the dates it enters and leaves. A sign that
appears twice means the planet backed into the previous sign during a retrograde and crossed again.
