There are some tiny variations because of the tilt of the earth, but we can say that days and nights are roughly equal at the equator.
On Equinoxes
no
This is called the "equinox", or "equal nights" - when the night and day are approximately the same duration.
The seasons are already figured out . . . the seasons change on the equinoxes (days and nights of equal length) and on the soltices (days and nights are the most different in length)
June 21st is the summer solstice in the Northern hemisphere, and for the northern hemisphere it is the longest day of the year. In the Southern hemisphere June 21st is the winter solstice. This means it is the shortest day of the year. This happens due to the earth's 23 degree tilt. The equator, however, is right between the hemispheres. So the days and nights are of equal length.
At the Equator at the two Equinoxes, Spring and Fall.
The equator experiences approximately 12 hours of daylight and 12 hours of darkness throughout the year due to its position on the Earth's axis. This means the equator has days and nights of equal length.
Days and nights are equal at the equator, an imaginary line that divides the Earth into the Northern and Southern Hemispheres. This phenomenon occurs during the equinoxes, which happen twice a year, around March 20-21 and September 22-23.
No, places on the equator do not have equal day and night on the June solstice. This phenomenon, known as the equinox, occurs when the tilt of the Earth's axis is perpendicular to the sun's rays, resulting in approximately equal day and night lengths.
Ther sun spends more time in the northern hemisphere, thus longer days and shorter nights. This is reversed when the sun spends more time in the southern hemisphere. At the equinox days, the sun spends time at the equator and the days and nights are equal.
On Equinoxes
the equator
no
When the Northern Hemisphere experiences days and nights of equal length, it is typically around the time of the vernal equinox in March and the autumnal equinox in September. During these equinoxes, the tilt of the Earth's axis is such that sunlight is distributed evenly across the equator, resulting in approximately 12 hours of daylight and 12 hours of darkness for most locations on Earth.
4 days/ nights and 18 hours
Africa is a very large continent, with parts in the northern hemipshere and part in the southern hemisphere, so the equator goes through it. The parts closest the equator experience no real difference in the length of days and nights throughout the year. Parts of Africa that are futher from the equator do experience a difference. There is a lengthening and shorterning of days. So it depends on where you are in Africa and the time of year.
Any place on earth that lie on the equator will have equal day and night time.
