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)

The beginning of summer in the northern hemisphere is marked by the summer solstice, which typically occurs around June 21st. This event signifies the longest day of the year, as the North Pole is tilted closest to the sun, resulting in increased daylight and warmer temperatures. The solstice is often celebrated in various cultures as a time of abundance and growth.
The Summer Solstice in the northern hemisphere, where the sun is highest declination.
The beginning of summer in the Northern Hemisphere is marked by the summer solstice, which occurs around June 21st. This is the longest day of the year, when the sun reaches its highest point in the sky. Additionally, rising temperatures, longer daylight hours, and the blooming of various plants and flowers are also signals of the arrival of summer. Cultural events and seasonal activities, such as outdoor festivals and vacations, further signify the onset of the season.
Maybe the right grammar there is 'at the beginning of summer'. Unless you are using a sentence with the phrase 'at the beginning of the summer vacation', that's when you're supposed to use 'the' before the word 'summer'.
The calendar is intended to mark the number of years since the death of King Herod the Great. The Roman abbot Dionysus Exiguus devised the new Christian calendar in 533. He knew that it was impossible to say when Jesus was born, but he knew, or thought he knew, when Herod died. So, he chose to begin his Christian calendar on the year of Herod's death, and he based this on the reign of the Roman emperor Augustus. Unaware that Augustus only adopted that name four years after his reign began, going by his birth name of Octavius until then, Exiguus commenced his calendar just 4 years too late.
The beginning of fall in the Northern Hemisphere is marked by the autumnal equinox, which occurs around September 22 or 23 each year. This event signifies the point when day and night are approximately equal in length. As the equinox approaches, temperatures typically begin to cool, and many trees start to change color, signaling the transition from summer to fall.
