A "sidereal day" on any planet is the time it takes the planet to rotate exactly once on its axis. On Earth that takes about 23 hours and 56 minutes.
There's also the "mean solar day". That depends on the position of the Sun in the sky, and on Earth it's 24 hours long. The "mean solar day" is what's normally meant by an "Earth Day".
The word "day " is also used for the equivalent things on other planets.
For example, Mars has a sidereal day of about 24 hours and 37 minutes, and
Mars has a solar day that's about 2 minutes longer.

What is the difference between the earth's rotation and the earths revolution. What causes the earth to have seasons. What causes the earth to have days and nights?
Those are three different questions; you would be better of asking them as three different questions on this site. The difference between rotation and revolution is that "rotation" refers to a movement of an object around its own axis; while "revolution" refers to a movement around an external object or axis - in this case, around the Sun.
How many hours in one day on venus?
The concept of a 24 hour day cannot be extended to Venus or Mercury as it is to Earth and Mars. On Earth, there is only a tiny difference between rotational time and solar time. On Venus, the difference between the sidereal day (243 Earth days) and the solar day (117 Earth days) makes clock times meaningless.A rotational day on Venus takes about 5832 Earth hours. A sunrise-to-sunrise day takes about 2802 Earth hours. Using either to design a clock would not be practical. Even the defining characteristic of day and night are not important because radar is used to observe the surface beneath the clouds. There is also virtually no difference between day and night temperatures on the surface.One concept that is used for time on Venus is the longitudinal noon, which establishes 360 divisions of rotational time to the 1.92 solar days that exist during the Venusian year (225 Earth days). Of course, the Sun would never actually be visible on the surface.
