165 days makes a year on Neptune.
there are 60,190 days.
One year on Neptune is equal to 164.8 Earth years. This is because Neptune's orbital period around the Sun is much longer due to its greater distance from the Sun.
Neptune has 60,190 number of days in a year.
I'm not sure how many days in one of Neptune years but one of Neptune's days is 16 hours and 7 minutes long. And one year is 165 earth years so 365 x 165 = 60225 earth days in one Neptune year.

60225 earth days = one year on Neptune
If your asking how long the day is, then it is 16.11hr., if your asking the length of the year, then 60190 days.
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.
One orbit for Neptune takes nearly 165 Earth years (164.79 years). This is approximately 60,190 Earth days. But a day (complete rotation) for Neptune is much shorter than Earth's, about 16 Earth hours. So there are about 89,666 "Neptune days" in a "Neptune year".
it is about 60,225 days for a year.
I image you are asking the age in terms of Neptune years or days. The Neptune year is about 164 earth years and each Neptune solar year is made of about 89666 Neptune solar days. This means that a Neptune solar day has a duration of about 1.5 earth days. Since January the first of year 2000, 4295 earth solar days are elapsed up to October 4 2012. This means that a person that was born on the earth on the first day of year 2000, when it is October 4 2012 on earth has an age of about 2863 Neptune days. They correspond to about 0.031 Neptune solar years, but the fact has to be considered that no man lives a whole Neptune year :-)
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.
