The Definition of a “Season” More specifically, the start of each season is marked by either a solstice (for winter and summer) or an equinox (for spring and autumn).

How does solstice affect seasons?
The Solstices (Summer & Winter) The summer solstice occurs at the moment the earth’s tilt toward from the sun is at a maximum. Therefore, on the day of the summer solstice, the sun appears at its highest elevation with a noontime position that changes very little for several days before and after the summer solstice.
Why do seasons start on the 1st in Australia?
Here in Australia we start the seasons on the first of the month. That means that in the Australian summer, the southern hemisphere is tilted more towards the sun. More sunlight equals warmer weather. The opposite happens in winter.
How are equinoxes different from solstices?
Equinox vs Solstice While the solstices result in a change of the length of night and day, the equinoxes do not. The summer and winter solstices result in the longest and shortest day of the year respectively while the equinoxes result in an equal amount of daylight and darkness received all across the earth.
What are the solstices and equinoxes?
So, at the end of the day, while solstices and equinoxes are related, they happen at different times of the year. Just remember that solstices are the longest and shortest days of the year, while equinoxes occur when the day and night are equally as long.

Because Earth actually travels around the sun in 365.24 days, an extra day is needed every fourth year, creating what we know as Leap Year. This also causes the exact date of the solstices and equinoxes to vary.
What determines the number of seasons on the calendar?
The natural rotation of Earth around the sun forms the basis for the astronomical calendar, in which we define seasons with two solstices and two equinoxes. Earth’s tilt and the sun’s alignment over the equator determine both the solstices and equinoxes.
Why do meteorological and astronomical seasons begin and end on different dates?
So, why do meteorological and astronomical seasons begin and end on different dates? In short, it’s because the astronomical seasons are based on the position of Earth in relation to the sun, whereas the meteorological seasons are based on the annual temperature cycle.
What is the summer solstice and winter solstice?
