The length of a year depends on how long it takes for the planet to orbit the Sun. A year each planet is: Mercury: 88 days, Venus 225 days, Earth: 365 days, Mars: 687 Days, Jupiter 12 Years, Saturn 29 years, Uranus 84 years and Neptune 165 years.

In astronomy there are a few definitions of year depending on what exactly is being considered. Perhaps most commonly, the Julian year is defined as 365.25 days. Additional definitions include the sidereal, anomalistic, vague, lunar, Gaussian, tropical, draconic year and several others which vary depending on the specific frame of reference.

long.
The earth orbits the sun in a year
The days are 24 hours long. (Strictly speaking that's called a "solar day".) There are 365 days in a year, except in a leap year when there are 366 days. (The Earth orbits the Sun in about 365.25 days. That's a sort of "year", but we like to have a whole number of days in a "calendar year".)
The dwarf planet Pluto is the planet with a year 248 earth years long.
The dwarf planet Haumea is the planet with a year 280 earth years long.
The dwarf planet Makemake is the planet with a year 310 earth years long.
