yes
Day and night are of equal length at the equator, which is an imaginary line that circles the Earth halfway between the North and South Poles. This phenomenon occurs during the equinoxes, which happen around March 20-21 and September 22-23 each year.
No, the length of day and night varies throughout the year due to the tilt of the Earth's axis as it orbits the sun. This results in the changing seasons and varying lengths of daylight and darkness.
The length of day and night changes more at the poles than at the equator throughout the year. At the poles, there are periods of continuous daylight in the summer and continuous darkness in the winter, leading to extreme variations in day length. In contrast, the equator experiences relatively consistent day lengths of about 12 hours throughout the year, with only slight variations.

The length of night on Earth is determined by the position of the Earth in relation to the sun as it rotates on its axis. The tilt of the Earth's axis and its orbit around the sun dictate the changing lengths of day and night throughout the year. Factors such as the time of year and location on Earth also influence the duration of night.
The two main factors would be that the seasons would not exist and the length of daylight and night time hours would not vary throughout the year at any given latitude. That the climate of any given latitude would change is inevitable with less variation throughout the year. The extent of the change is almost impossible to predict
how does earths distance from the sun change throughout the year
The length of day and night depend upon the season of the year and the latitude of the desert. Over a year it averages 12 hours of day and 12 hours of night.

The equator.
The lengths of day and night vary around the Earth due to its axial tilt and elliptical orbit around the sun. Different latitudes receive different amounts of sunlight throughout the year, leading to variations in day length. This results in the changing durations of day and night throughout the year at different locations on Earth.
