Summer soltice 21 June, and winter soltice 21 December.
march 21 and 20th the sun is directly overhead the equator
The equinoxes, about 22 March and 22 September.
The Earth is still tilted on its axis however.
During spring and autumn both hemisphere receive equal amount of daylight.
Twice a year on the equinoxes.
The spring and vernal (autumn) equinoxes.

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.

When night and day are approximately of equal length occurs twice per year. In the northern hemisphere these days are called the Vernal Equinox (20-21 March) and the Autumnal Equinox (22-23 September). However, as these seasons are reversed in the southern hemisphere, current usage is the March Equinox and the September Equinox.
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)
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.
They are equal.
Because the Earth is tilted on its axis. In the winter, the Northern Hemisphere is tilted away from the sun, so the path you travel on the Earth is more in the dark. Note that this is not true all over the Earth. On the equator, the days and nights are always equal. In the Southern hemisphere, it's the opposite of the Northern hemisphere.
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.

Northern and southern hemisphere. And eastern and western hemisphere.
A big difference/similarity is seasons. The northern and southern hemisphere have opposite solstices, but their equinoxes are the same. So when the northern half is having summer, the southern half is having winter. But the North's fall is the South's spring, so they both have equal days and nights. A difference is population/pollution. Approximately 90% of the population resides within the northern hemisphere. Along with most of the population is most of the pollution too. Another difference is moon phases. The northern hemisphere has moon phases change from right to left. Waxing moons gain illumination from right to left, and waning moons lose illumintation from right to left. But in the southern hemisphere, the opposite is true. The moon changes from left to right. These are the main similarities and differences i can think of. Hope they help!
A hemisphere is exactly 1/2 of the earth. We speak of the Western Hemisphere, the Eastern Hemisphere. the Southern Hemisphere, and the Northern Hemisphere.

It should be remembered that the seasons are diametrically opposed in the hemispheres. When it is summer in the northern hemisphere it is winter in the southern one. Seasons officially start and end on the solstices and equinoxes. The solstices are the days on which daylight or night time are the longest. When the day is longest in the northern hemisphere night is longest in the southern. The equinoxes are when day time and night time are equal which varies depending on your latitude. (Except at the equator)
Don't understand your question. Equinox means "equal night", meaning the Northern Hemisphere and Southern Hemisphere both receive equal amounts of day and night. It signifies the beginning of Spring in the northern hemisphere and the beginning of Fall in the southern hemisphere.
