Computed from the actual motion

The nearest Neptune retrogrades either side of 1917

Previous

1916 Ended April 10, 1916 after 157 days, moving back 2.81° through the zodiac.

Next

1918 Begins November 12, 1918 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 1917

Neptune through the zodiac in 1917

Every sign Neptune occupies during 1917, 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 Leo From Jan 1 – Dec 31 and beyond

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