Pretty much, yes. You have the spring (vernal) and autumn (autumnal) equinoxes, so it's around that time. Midsummer's day is around the first day of summer. But the equinoxes aren't precisely (to the smallest fraction of a second) halfway between, because the velocity of earth's orbit is constantly changing throughout the year.
The revolution of the Earth around the sun causes the changing seasons and the positions of the solstices and equinoxes. The solstices occur when the Earth's axis is tilted most toward or away from the sun, leading to the longest and shortest days of the year. The equinoxes occur when the tilt is at a right angle to the sun, resulting in day and night being of nearly equal length.
September 22-23 & March 21-22. They mark the beginnings of autumn and spring respectively, in the northern hemisphere. They mark the beginnings of spring and autumn, respectively, in the southern hemisphere.The Spring equinox and the Autumnal equinox occur when the length of daytime and the length of nighttime are exactly equal to each other.
Solstices and equinoxes are different in terms of the position of the Earth in relation to the sun. Solstices occur when the Earth's axis is tilted either towards or away from the sun, resulting in the longest or shortest day of the year. Equinoxes, on the other hand, occur when the Earth's axis is not tilted towards or away from the sun, resulting in equal day and night lengths.
The September equinox can occur at any time from the 21st to the 24th of September.
The Sun is over Earth's equator during the equinoxes, which occur around March 20th (spring equinox) and September 22nd (fall equinox) each year. This is when day and night are approximately equal in duration all over the world.
Equinox
The solstices occur at the points where the Earth is either closest to, or farthest away from, the Sun. The equinoxes are the mid-points between the solstices - where the day & night are of equal length.
Two equinoxes (from the word 'equal') occur each year: one in the Spring, called the vernal equinox from a word for green-ness, and also the autumnal equinox in the Fall. On the day and hour of the equinoxes, days and nights are the same length of time.
The first day of a season is called the "equinox" or the "solstice," depending on the season. The spring and autumn equinoxes occur around March 20-21 and September 22-23, while the summer and winter solstices occur around June 21-22 and December 21-22.
They occur in December and June, on the 21st or 22nd of the month.
For example, north-east is halfway between north and east.
At the same time as in the Northern Hemisphere The equinoxes are around March 21 and September 22 each year (the calender date shift slightly due to the uneven number of days in a year - that's why we have leap years almost every fourth year- to bring the equinox es and solstices back to the same calender date).
A equinox occur's only about 2 times a year.
An equinox in astronomy is the moment in time when the centre of the sun can be observed to be directly above the Earths equator, occurring around March 20th and September 23rd each year.
Solstice is the middle of Summer and Winter, Equinox is the middle of Spring and Fall.
November
Temperate climates occur in the middle latitudes, the region halfway between the equator and the poles.
