A day on Mercury is twice as long as its year. A day on Venus is also longer than a year- it is 243 Earth days long due to Venus' slow rotation around its axis. At the same time the year on Pluto is the longest one in our Solar System. A day on Pluto is 6.39 times longer than a day on Earth and it takes 247.7 Earth years for Pluto to orbit the Sun just once.
