Slower than a year
Measured against the stars, Venus needs longer for a single turn than for a full lap around the Sun.
And backwards, too
Venus spins the opposite way to Earth. There the Sun rises in the west and sets in the east. Among the planets only Uranus does the same. Why Venus turns so slowly and backwards is still not known.
From sunrise to sunrise
117daysis one solar day on Venus
Because Venus spins against its direction of travel, the Sun in a sense comes toward it. So from one sunrise to the next takes "only" just under 117 Earth days. A Venus year holds almost two solar days.
