Venus is the planet in our solar system where a day is more than half as long as its year. A single rotation on its axis (a Venusian day) takes about 243 Earth days, while it takes only about 225 Earth days to complete one orbit around the Sun (a Venusian year). This means a day on Venus is longer than its year.
Mercury is the planet with an 88-day year.
