Yes, a planet's spin one time on its axis is defined as that planet's day; 24 hours in the case of our Earth. In astronomical circles this is referred to as rotation, distinct from revolution which is applied to the time it takes for the planet to orbit around the Sun, which is that planet's year.
On the planet Venus, it takes 5,832 hours to complete a full rotation on the axis
During its rotation around its own axis half of the planet faces the sun [day] and half faces away from the sun [night] As the planet continues to turn so night slowly turns into day and then day into night and so on.
A planet's rotation on its axis determines the length of its day.
A planet rotates (spins) about its own axis, giving rise to its day. Earth's day is about 24 hours. This motion is distinct from the orbital motion (revolution about the Sun) which is the planet's year.
When Earth's core spins, the planet turns on its axis and completes its rotation. One complete rotation is one day and night.

It's called - a "Day"
All planets turn on their axis. This is called the planet's rotation; one complete rotation is equal to one day on that planet.
