Because Uranus' axis of rotation is in the plane of its orbit, the poles of the planet face the Sun. This means that each pole is illuminated for half of its 84.3 (Earth) year orbit, making a day on the planet last roughly 42 Earth years.
There seems to be some confusion to who ever is asking this question.
Uranus has seasons that last for about 21 years, but a day on Uranus is 17 hours 14 minutes whereas a year on Uranus is 84.323 Earth years.
No planet known, has a year (time taken to orbit the Sun once) of 42 Earth years. [See related question]
The only relation to 42 is the amount of sunlight the poles get. The poles get 42 years of sunlight followed by 42 years of darkness.

Every Year, but each year is different for each planet: Mercury- 88 Earth Days (.25 Earth Years) Venus- 255 Earth Days (.7 Earth Years) Earth- 365 Earth Days (1 Earth Year) Mars- 687 Earth Days (1.8 Earth Years) Jupiter- 4,346 Earth Days (11.9 Earth Years) Saturn- 10,774 Earth Days (29.5 Earth Years) Uranus- 30,680 Earth Days (84 Earth Years) Neptune- 60,625 Earth Days (165 Earth Years)

The length of a year for each planet increases as each planet is farther from the Sun. The lengths are: Mercury: 88 days, Venus: 225 days, Earth: 365 days, Mars: 687 days, Jupiter: 12 years, Saturn: 30 years, Uranus: 84 years and Neptune: 165 years.
The planet Mercury completes one revolution in its orbit around the Sun in about 88 Earth days (87.969 days, to be more exact). This is about 0.241 Earth years.

Every planet revolves around the sun each year, but years are different on each planet: Mercury- 88 Earth Days (.25 Earth Years) Venus- 255 Earth Days (.7 Earth Years) Earth- 365 Earth Days (1 Earth Year) Mars- 687 Earth Days (1.8 Earth Years) Jupiter- 4,346 Earth Days (11.9 Earth Years) Saturn- 10,774 Earth Days (29.5 Earth Years) Uranus- 30,680 Earth Days (84 Earth Years) Neptune- 60,625 Earth Days (165 Earth Years)

The planet nearest to having this is Mercury.Actually, Mercury has nearly 88 Earth days in its year.Also, the planet Uranus has about 84 Earth Years in its year.

88 Earth days
No planet in our solar system has days longer than one Earth year. Venus has the longest day -- it's 243 Earth days.
Most years have 365 days, but there are also leap years that have 366 days. The length of the year is designed to give us consistent seasons. The planet Earth travels in its orbit around the sun in a year. Because the length of the year in days is the same as the length of the orbit, we always have winter and other seasons during the same months.

A year on our planet is 365.25 Earth days. Other planets take more or less time depending on their orbital distances from the Sun. Mercury - 88 Earth days Venus - 225 Earth days Mars - 687 Earth days Jupiter - 11.86 Earth years Saturn - 29.46 Earth years Uranus - 84 Earth years Neptune - 164.8 Earth years Pluto (now a dwarf planet) - 247.7 Earth years
The earth's rotation and orbital motion is responsible for the days and nights on the planet. This movement is also responsible for the changes in the seasons.
Uranus which has an orbital period of 84.016846 years which is 30,687.153 days.
One revolution= 1 year, but each year is different for each planet: Mercury- 88 Earth Days (.25 Earth Years) Venus- 255 Earth Days (.7 Earth Years) Earth- 365 Earth Days (1 Earth Year) Mars- 687 Earth Days (1.8 Earth Years) Jupiter- 4,346 Earth Days (11.9 Earth Years) Saturn- 10,774 Earth Days (29.5 Earth Years) Uranus- 30,680 Earth Days (84 Earth Years) Neptune- 60,625 Earth Days (165 Earth Years)
