This is only in the Northern Hemisphere, north of the Tropic of Cancer. The summer solstice occurs because the Earth is tilted toward the Sun so the most direct rays hit there. the greatest temperature variation is at mid-latitude, at 45 degrees North or South. I live in Toronto, near this region.

The Earth is tilted by 23 1/2 degrees. During the Summer months,
the north is pointed toward the Sun allowing more direct sunlight.
During the winter, we are tilted away from the sun so the sunlight
is more indirect as the sun seems lower in the sky.
There are 4 cardinal points in our calender;
Summer solstice, autumnal equinox, winter solstice and vernal equinox.
Beginning of summer, fall, winter and spring. This coincides
with the position of earth as it goes around the sun.
Each of the cardinal days can take place over a three day period,
20th, 21st, 22nd. On June 22nd, summer solstice, it is the longest
day of the year. It is also the day that the north pole is pointing
directly at the sun. The next day it will have passed this point
and start pointing away from the sun, hence, the days will also start
getting shorter. For further info,

Because of the tile of the earth, the northern hemisphere is pointed the most towards the sun on June 22. Because of that an some other geometry involving angles and the rotation of the earth, the sun is visible on the northern hemisphere for the greatest amount of time on that day. Therefore, it is the longest day. Solstice is an ancient term and was used to describe the longest and shortest day of the year. The summer solstice is on June 22 and the Winter is Dec 22. It is actually the day that the earth's angle points the most (summer) or the least (winter) towards the sun. The term is derived from "sol" or "sun god".
Hope this helps.

In the northern hemisphere, June 21st is the day when the Earth faces the sun for the longest amount of time. From today onwards, the earth's orbit means that the sun doesn't appear in the sky as long as it does at the moment carrying on until December 21st which is the shortest day in the northern hemisphere.

Be aware though that for the southern hemisphere the reverse happens.

Solstice, from the Latin for sun stands still, in astronomy, either of the two points on the ecliptic that lie midway between the equinoxes (separated from them by an angular distance of 90°).

At the solstices the sun's apparent position on the celestial sphere reaches its greatest distance above or below the celestial equator, about 23 1/2° of arc. At the time of summer solstice, about June 22, the sun is directly overhead at noon at the Tropic of Cancer.

In the Northern Hemisphere the longest day and shortest night of the year occur on this date, marking the beginning of summer. At winter solstice, about December 22, the sun is overhead at noon at the Tropic of Capricorn; this marks the beginning of winter in the Northern Hemisphere. For several days before and after each solstice the sun appears to stand still in the sky, i.e., its noontime elevation does not seem to change from day to day.

You need some fundamental knowledge of the Earth and the effect of its orbital tilt.

From north or south of the equator on the Earth, it looks like the sun moves its starting point each day north or south, and stops, then moves back in the other direction. The day when the sun seems to stop is the solstice (latin for "sun stop"), The summer solstice is the northernmost point in the northern hemisphere, and the winter solstice is the southernmost point in the southern hemisphere. The spring or vernal equinox and the fall or autumnal equinox occur when the sun is exactly over the equator and the day and night are equal.

Because it's the moment when the Earth will stay longer near the Sun, so the light will last more than usual, and tomorrow (the 23rd) the Earth will start "going away" from the Sun and that will make the daylight last a shorter time. Hope it's understandable!

It's the longest day of daylight hours....just like in winter there is a shortest day. It's just how it works...it build up to be long days of sunshine and then wanes back to much shorter days and then repeats....Best wishes

geniotrapad is wrong, actually the earth is the farthest from the sun now and will start getting closer. It's the tilt of the earth that give us the most sunlight hours, not closeness to the sun.

it was june 21st (acc to wikipedia.org)
the earth was closest to the sun
