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.

…and back into Aries
Neptune retrograde in Aries reviews ideals connected to action and identity. Causes pursued with fervor are examined for illusion. It suits clarifying what is worth fighting for.
It begins in Leo season and ends in
Capricorn season.

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 2039
Neptune through the zodiac in 2039
Every sign Neptune occupies during 2039, 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.
