Like many other things, that will depend on your precise location; the number of daylight hours in Presque Isle, Maine will be longer than the number of daylight hours in Newport, Rhode Island.
Here is the sunrise/sunset data for Presque Isle, ME on June 21, 2010:
Sunrise 4:38 a.m.
Sunset 8:29 p.m.
Twilight at this latitude adds about a half-hour at either end of the day.
So, it looks like about 15.8 hours. It would be somewhat less south of Presque Isle, and a little longer anywhere north of there.
The summer solstice happens. The summer solstice is also the winter solstice in the opposite hemisphere. On the summer solstice (on the northern hemisphere), the northern hemisphere is tilted most to the sun, giving 24 hours of light to the Arctic Circle and 24 hours of darkness to Antarctica on the day of it.

Astronomical twilight lasts all night in London during the summer solstice, however due to the urban light pollution it is hardly noticeable.
Oh, dude, the shortest day of the year is like December 21st, the winter solstice, when the sun's like, "I'm out early, gotta catch some Z's." And the longest day, bro, that's June 21st, the summer solstice, when the sun's like, "I'm staying up late, party time!" So, like, the shortest day is around 9 hours of sunlight, while the longest day is like 15 hours of sun-soaked fun.
Two equinoxes (from the word 'equal') occur each year: one in the Spring, called the vernal equinox from a word for green-ness, and also the autumnal equinox in the Fall. On the day and hour of the equinoxes, days and nights are the same length of time.

No, there were no light pollution in London, England, it would not be pitch black at Summer Solstice because there is a full moon.================================Answer #2:At the time of the Summer Solstice, the sun's declination reaches roughly +23.5°.London's latitude is in the neighborhood of 51.5° North. That's still 15° southof the Arctic Circle, so the sun dips as much as 15° below London's horizon.That ought to be plenty to guarantee a very dark night.There's no connection between the Summer Solstice and the phases of the Moon.
In England during the winter months, there are typically around 8-9 hours of daylight per day. The shortest day of the year, known as the winter solstice, occurs around December 21st, where there may be as little as 7-8 hours of daylight.
Summer typically has more daylight hours than winter due to the Earth's tilt and position in its orbit. During the summer solstice, the Northern Hemisphere receives the most daylight hours, while during the winter solstice, the Northern Hemisphere receives the fewest daylight hours.
The solstice is day of the year with the longest period of light (the summer solstice) or the longest period of night (the winter solstice). The vernal equinox (spring) and autumnal equinox (fall) are the two days in the year in which the periods of light and periods of darkness are exactly the same duration.
The day with the longest daylight hours in the year is the summer solstice, which typically occurs around June 21st in the Northern Hemisphere and around December 21st in the Southern Hemisphere. On this day, the sun reaches its highest position in the sky, resulting in the longest period of daylight.
Immediately after the summer solstice, the time between sunrise and sunset starts to diminish.
On a solstice, it is only at the equator that the hours of light and dark are equal. At other parts, they would be different with one of the Poles experiencing 24 hours of daylight and the other Pole experiencing no daylight. If it is the June solstice, then it is the North Pole with 24 hours of daylight and the South Pole with none, while it is the opposite in the December solstice. It is at the equinox that the amount of daylight and darkness hours are equal around the world.
spring time at the poles brings the most sunlight. fall brings darkness. it rises slowly in the spring and days become 30 hours. and by fall it's the opposite. I think that the summer solstice falls in mid June (June 21-until 2039).
The day gets longer in the evening, as the amount of daylight increases leading up to the summer solstice. Morning will begin to get longer after the summer solstice as daylight decreases.
That would depend on where in the world you are. If you were at the North Pole there would be 24 hours of daylight, while at the South Pole there would be no daylight. At points in between the two poles the amount of daylight would be different. At the equator the amount of daylight hours would be about 12 hours.
