Computed from the actual motion

The nearest Neptune retrogrades either side of 1990

Previous

1989 Ended September 21, 1989 after 160 days, moving back 2.78° through the zodiac.

Next

1991 Begins April 19, 1991 and runs 160 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.
