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 1977

Previous

1976 Ended August 23, 1976 after 160 days, moving back 2.77° through the zodiac.

Next

1978 Begins March 20, 1978 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.
