Here's why:

* Venus's rotation is very slow: Venus rotates incredibly slowly on its axis. One day on Venus (the time it takes to complete one rotation) is equivalent to 243 Earth days.

* Venus's year is shorter than its day: Venus orbits the sun much faster than Earth, completing one orbit (a year) in 224.7 Earth days.

Therefore, since one Venus day is 243 Earth days, seven Venus days would be approximately 1,701 Earth days, which translates to about 1.9 Earth years.
