When the day and night are equal it is called the equinox (means literately equal night). It happens twice a year. Once in the sping called the vernal equinox which occurs on the March,20 or 21 each year. Once in the autumn or fall called the autumnal equinox which happens September, 21 - 22each year.
The two days of the year when there is exactly 12 hours of night and 12 hours of day are the equinoxes. They occur around the 20th of March and the 23rd of September each year.
The length of day and night on Earth are not always equal. The amount of daylight and darkness varies depending on the time of year and the latitude of a location. This difference is more pronounced the closer you are to the poles and during the equinoxes.
The Equinox (Vernal & Autumnal) There are only two times of the year when the Earth's axis is tilted neither toward nor away from the sun, resulting in a "nearly" equal amount of daylight and darkness at all latitudes. These events are referred to as Equinoxes
No. That would be an Equinox. The solstice is when the earth is tilted at maximum angle, (23 1/2 degrees) from the plane of the orbit around the sun. Either north or south pole is closer. The exact difference of night and day will vary depending on where you are on earth.

An equal day and night occurs twice per year on the summer and winter equinox.

The equinoxes are the two dates each year when the day and the night are of equal length.
The date when daylight hours are equal to night hours is known as the equinox. This occurs twice a year, in March (spring equinox) and September (fall equinox), when the tilt of the Earth's axis is inclined neither away from nor towards the Sun, resulting in nearly equal day and night lengths.
The time of year with equal time of night and day is the equinox.
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.
The equinox is when, twice each year, day and night are of equal length (about 22 September and 20 March).
Two times
Twice every year when night and day are of equal length.
Twice, at the Summer and Winter Solstaces.
