Because of the difference of speed the planet is spinning, for example Neptune spins in speed greater than 2000 kph so its day and night is fast.
That simply means that some planets rotate faster than others.

Mars. Its day-night cycle is only about 40 minutes longer than Earth's.
It depends where you are on the planet. For most of the planet the day-night sequence is repeated every 24 hours. However at the poles the day night sequence is repeated only once every year.
The length of time it takes to complete one full rotation
During the day, sunlight provides both light and heat. At night, it is dark and it cools off.
The planet is Mercury. (Some people think it is Venus, but it is Mercury.)
Because of the difference in speed of rotation of each planet.
no,planet has a star day and night
Because different planets have different diameters and spin at different rates.
Mars. Its day-night cycle is only about 40 minutes longer than Earth's.
Some planets rotate faster or than others. Also the planets take different times to orbit the Sun.
due to elliptical shape of earth,the size of days and night are vary
Mars rotates, and therefore possesses both day and night. It's length of day is believed to be much the same as that of earth.

Across the whole planet the day and night length are the same and it is the first day of Spring in the northern hemisphere and the first day of Autumn in the southern hemisphere.
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.
During the Autumn equinox the length of the day and night are nearly equal. The length of the day on the equinox is approximately twelve hours.
