Neptune's 'day' lasts for 367.49 Earth days.

Neptune
It takes 165 Earth years for Neptune to go around the sun.It takes 16 Earth hours to have a full day.
Neptune takes about 165 Earth years to orbit the Sun and about 16 hours to rotate on its axis.
Axis
Neptune takes about 16 hours to complete one rotation on its axis. This rapid rotation contributes to its dynamic atmosphere and strong winds. In contrast, Neptune takes approximately 165 Earth years to complete one orbit around the Sun.
The Moon both revolves (orbits) around the Earth and rotates on its axis. It takes about 27.3 days for the Moon to make one orbit around the Earth and also about the same amount of time (27.3 days) for it to complete one rotation on its axis. This synchronous rotation is why we always see the same side of the Moon facing Earth.
It takes roughly 6.4 Earth days for Neptune to rotate on it's axis.
Venus rotates on its axis more slowly than it revolves around the sun. It takes approximately 243 Earth days for Venus to complete one rotation on its axis, but only about 225 Earth days to complete one full orbit around the sun.
Neptune takes 16 hours 6 minutes and 36 seconds to rotate or spin once on its axis, or 0.67125 Earth days.
Neptune's rotation period takes 16hours and 17minutes to rotate on its axis.
The Earth rotates on its axis and revolves around the sun.
