16.5 Earth Hours.
On Neptune, a day is about 16 Earth hours and 6 Earth minutes long. Neptune has a much longer day than Earth due to its slow rotation, which results in a longer day-night cycle on the planet.
Neptune completes a full rotation on its axis in 15 hours, 57 minutes, and 59 seconds. This is in terms of Earth hours, making a day on Neptune a short one.
The length of a day, or sidereal period, on Neptune is 16 hours 6 min 13 seconds (0.6713 days) Because Neptune is not a solid body, its atmosphere undergoes differential rotation. The wide equatorial zone rotates at a period of about 18 hours, at the polar regions the rotation period is about 12 hours.
It takes 165 Earth years for Neptune to go around the sun.It takes 16 Earth hours to have a full day.
A day on Neptune is 16 hours, 6 minutes and 36 seconds. A year on Neptune is 164.8 Earth years.

Neptune has a day and night cycle as does all the planets. Neptune's day and night are shorter than Earth's because it takes Neptune only 16 hours to complete a rotation.
Neptune takes about 16 hours to complete one rotation on its axis. This rapid rotation results in a day on Neptune being significantly shorter than a day on Earth. Despite its large size, Neptune's quick rotation contributes to its dynamic atmosphere and weather patterns.
There are about 0.6713 Earth days or about 16 hours, 6 minutes, 36 seconds in a day on Neptune. (see related link on Neptune)16.11 Earth hours
The rotation period of Neptune is 16.1 earth hours.
The day on Neptune is 16 hours long, so the average night would be eight hours long. this is bull and i am a hermaphrodite
it takes Neptune 164.79 years to revolve around the sun. There are two rotations for a planet, that of its own rotation, and that of its rotation round the sun. Equivalent to our Day and Year.
