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.

Computed from the actual motion

The nearest Neptune retrogrades either side of 1931

Previous

1930 Ended May 12, 1930 after 157 days, moving back 2.79° through the zodiac.

Next

1932 Begins December 12, 1932 and runs 157 days.

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 1931

Neptune through the zodiac in 1931

Every sign Neptune occupies during 1931, 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.

Neptune in Virgo From Jan 1 – Dec 31 and beyond

The whole year is spent in one sign — a sign of how slowly Neptune moves.
