It is the Summer solstce. In the northern hemisphere it is the longest day of the year. In the Southern Hemisphere it is the shortest.
In the Southern Hemisphere, from June 21 to December 22, the days gradually get longer as this period includes the summer solstice where the sun is at its highest point in the sky. From December 22 to June 21, the days gradually get shorter as this period includes the winter solstice where the sun is at its lowest point in the sky.
The sun's rays strike Earth at their northernmost position during the summer solstice (around June 21 in the Northern Hemisphere) and at their southernmost position during the winter solstice (around December 21 in the Northern Hemisphere).
After June 21, which is the summer solstice, the daylight period in the northern hemisphere starts to decrease gradually. This marks the beginning of summer transitioning into fall, with days becoming shorter until the winter solstice in December.
1) The UK is NOT closest to the sun on 21 June (its closest somewhere around January). 2) It's not hottest on the longest day of the year because of the latent heat of the earth. Note that it is coldest before dawn, NOT just after sunset.
If you mean the longest: When you have the longest day, you'll also have the shortest night, and vice versa. In the northern hemisphere, the longest day is around June 21, and the shortest day is around December 21. In the southern hemisphere, it is the other way round.
Days get shoter
it is the longest day of the year in the northern hemisphere but its the shortest in the southern
it happens every year around about June or July
These are the solstices. On or around December 21 in the northern hemisphere and on or around June 21 in the southern hemisphere.
That depends on your location on Earth. In the northern Hemisphere it is in December, in the Southern Hemisphere its in June. Roughly around the 21st of December and June respectively. Of course that is only looking in terms of daylight. All days are 24 hours long, except when the clocks change. When they go back, that gives an extra hour, so there are 25 hours in that day and when they go forward, there are 23 hours in that day. In some countries the clocks don't change, so again it would depend on where you are in the world.
That happens at some point on the equator, at a single moment, on two days of the year ... near March 21 and near September 21.
The longest day happens on the summer solstice, June 21 in the north and December 21 in the south e.g. Australia.
around June 21
the season it is in the southern hemisphere is winter because in the northern hemisphere in June 21 in is summer so it is the opposite.
