When does summer officially start and end?
The official start of the summer in Belgium is near June 21. The day varies because of the positioning of the sun during the summer solstice.
Not really sure if there is a difference between "official" and "technical" or "astronomical" start to summer. Northern Hemisphere summer begins-- astronomically/technically--… at the moment of the summer solstice, June 21. The solstice is when the sun reaches its highest altitude in the north, the Tropic of Cancer. I believe another way to think of the summer solstice is when the plane containing the earth's pole and the center of the sun is exactly perpendicular to the earth's orbital plane in June.
Summer begins each year on the day of the summer solstice, which ison or near June 21 and ends each year on the day of the autumnalequinox, which is on or near September 22.
Summer officially ends at different times for different people. Summer officially ends for school kids when they start the next school year.

The official start of summer depends where in the world you are. In the northern hemisphere, summer occurs from May to September, give or take a week or so. The hottest months… are June, July and August. The official dates depend on the country or area where you live, and can vary for meteorological reasons. In the southern hemisphere, summer happens between November and March, again, give or take a bit either way. The hottest months are December, January and February. In China the seasons are based on 24 solar periods, dependent on the equinoxes. In the southern hemisphere countries of Australia, New Zealand and South Africa, official dates are: Summer - December 1 to February 28 or 29 Autumn - March 1 to May 31 Winter - June 1 to August 31 Spring - September 1 to November 30
In Antarctica, the first day of summer is December 21, and the first day of fall is March 21. This is true everywhere in the Southern Hemisphere.
