(For information on the exact minute regarding the 2010 Summer Solstice, see the Related question.)
===========================================
The sun reaches the Summer Solstice at a moment in time, regardless of
where you are when you hear or read about it, and regardless of whether
or not you're even aware of it.
This year, that moment in time is 6:28 AM Central Daylight Time on June 21,
and whatever the same moment is called in other places around the world.
Whether the "summer" solstice is in June or December depends on your hemisphere.

In the Northern Hemisphere, summer begins on the day of the summer solstice, June 21st. Of course, because the Southern Hemisphere is pointed away from the Sun at this time, June 21st is the first day of winter there.
Summer begins at the June solstice in the north and at the December solstice in the south. Summer begins on June 20th or 21st, when the sun is furthest north, known as the Summer Solstice. Here is a link to some additional information: http://www.calendar-updates.com/info/holidays/us/summer.aspx
The winter solstice - around December 21 - the days then begin to get longer or "draw out" until The summer Solstice in June - for the Northern hemisphere - opposite in the Southern hemisphere
Winter Solstice
June 21st, which the Summer solstice for those of us in the Northern hemisphere, is the winter solstice for those in the southern hemisphere. Their summer is our winter, their spring is our autumn, and so on. This is due to the ~24 degree tilt of the earth's axis of rotation, which stays at a static angle throughout earth's revolution around the sun. This angle is responsible for the amount of solar radiation (sunlight) a given point on the earth would accumulate throughout a day, which is a single rotation of the earth about it's axis.

The "line" between spring and summer is the Summer Solstice, usually June 20th or 21st in the US and the Northern Hemisphere.
In the summer time earth has more heat because the earth is facing towards the sun and the sun is giving us more sun light. This is called the summer solstice.
Solstice - US band - was created in 1990.
Summer, between Summer solstice (June) and Automn equinox (September)
In the Northern Hemisphere, summer begins on the day of the summer solstice, June 21st. Of course, because the Southern Hemisphere is pointed away from the Sun at this time, June 21st is the first day of winter there.
Summer begins at the June solstice in the north and at the December solstice in the south. Summer begins on June 20th or 21st, when the sun is furthest north, known as the Summer Solstice. Here is a link to some additional information: http://www.calendar-updates.com/info/holidays/us/summer.aspx
In the US, summer is traditionally June, July, and August, although the season is defined as from June 20/21 (June solstice) to September 22/23 (September equinox).
Switzerland is the best place for summer
The last Olympics in the United States was the 2002 Winter Olympics in Salt Lake City, Utah. The last Summer Olympics that took place in the United States was the 1996 Summer Olympics in Atlanta, Georgia.
Neither. The United States (assuming that's what you meant), is a territory of land on the surface of the planet earth and thus does not move in respect to the rest of the planet. If your question was: "Is the planet earth closer to the sun during the winter or the summer of the northern hemisphere?" Then the answer would be that the planet earth is slightly closer (by 0.033 AU or ~ 5 million km) to the sun during the winter solstice than the summer solstice.
In the United States, the most hours of daylight (sunlight) is on June 21st, also know as the Summer Solstice. The Winter Solstice is on December 21st and is the shorted say of the year (or, the least hours of daylight). The two equinoxes are March 21st and September 21st which is the first day of spring and the first day of fall. In the southern Hemisphere though, everything is flipped so the Summer Solstice is December 21st, the Winter Solstice is June 21st, the Spring Equinox is September 21st and the Fall Equinox is on March 21st. This is all because of the Moon phases.
