Neptune is not named after a day. It is named after the Roman god of the sea.
The rotation of the planet Neptune is much faster than Earth's. It completes a rotational "day" in about 16 Earth hours. So in an Earth year (365.25 Earth days), Neptune completes about 544 Neptune days. In a Neptune year, there are about 89,666 Neptune days.
Neptune is always spinning.
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.
A day on Neptune is 16 hours, 6 minutes and 36 seconds. A year on Neptune is 164.8 Earth years.i

A day on Mars is about 24.6 hours. A year on Mars takes 687 Earth days.It takes Mars this long to orbit the sun.
A day on Neptune is 16 hours, 6 minutes and 36 seconds. A year on Neptune is 164.8 Earth years.
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.
