First day of summer?
The first day of spring, summer, fall and wintercan either be defined using atronomical events like solstices and equinoxes, or they can be determined based on meteorological factors, average temperatures.
In the USA and some other areas in the northern hemisphere, the summer solstice marks the first day of summer. However, the official date for the first day of summer varies depending on the country's climate.
