Neptune has completed MANY orbits around the Sun since its formation. However, an interesting note is that since its "discovery" in September of 1846, it has not yet completed one orbit, which takes 164.8 Earth years. This will occur in June, 2011.

Neptune takes about 165 Earth years to orbit the Sun. That's one Neptune "year" of course. Neptune's "day" is about 16 hours and 6 minutes ( 16.1 hours). That's the time it takes to spin on its axis once. From that you can work out how many Neptune days the orbit takes, if you want. I make it to be about 89838 "Neptune days". You can say Neptune "year" and Neptune "day", but the terms "week" and "month" are normally only used for planet Earth. Also when I've used "hour" in this answer I mean an Earth hour. This is normal in books on astronomy.
It takes Neptune 165 Earth years to circle the Sun ONCE. The amount of time it takes for any planet to circle the sun is one year. Its year is longer because it is further away. Its orbit is much larger than Earth's.

62 moons orbit Saturn, 67 orbit Jupiter, 5 orbit Pluto, 14 orbit Neptune, and 27 orbit Uranus.

Neptune orbits the sun, not Earth. Its orbital period is 60,182 Earth days, or about 165 Earth years.
It takes roughly 6.4 Earth days for Neptune to rotate on it's axis.
