Because the planets are not rotating very fast.
A day is defined as the time it takes a planet to rotateonce on it's axis.
A year is defined as the time is takes a planet to revolvearound the Sun.
Mercury is in a 3:2 orbital resonance with the Sun and rotates 3 times for every 2 times around the Sun.
Venus rotates so slowly, that by the time it has rotated once, it has gone around the Sun 1.085 times.
