it take Venus about 42 earth days to make a complete rotation on its axis
Roughly 4 minutes less than 24 hours.
An Earth complete spin is 24 hours.
The Earth takes 23 hours, 56 minutes to complete a sidereal orbit (the length of time the constellations appear to take for one rotation), but 1 day, or one rotation of the Earth on its axis is 24 hours.
29 Earth days.
The earth revolves on its axis in the direction it does because its rotation is a function of the manner in which the materials that formed it accreted. It also is affected by the catastrophic strikes of large planetary bodies (if any) and large space rocks. It takes a standard day for the earth to make one complete revolution on its axis. (One complete revolution of the earth on its axis is, by definition, a day.)

It does NOT orbit on its axis, but rotates on its axis. It takes 24 hours, one day, to make one complete rotation. However, It does ORBIT the Sun. It takes the Earth 365.25 days, one year, for make one complete orbit of the Sun. Whilst it is making this orbit it is also rotating on its axis, as above.
365 days, or a year.
