Summer Solstice..lets celebrate!

To go the site that has this wealth of info click the title of the post :)

In the northern hemisphere, the longest day of the year (near June 22) when the Sun is farthest north. In the southern hemisphere, winter and summer solstices are exchanged. The summer solstice marks the first day of the season of summer. The declination of the Sun on the (northern) summer solstice is known as the tropic of cancer (23° 27').
The summer solstice is the longest day of the year, respectively, in the sense that the length of time elapsed between sunrise and sunset on this day is a maximum for the year. Of course, daylight saving time means that the first Sunday in April has 23 hours and the last Sunday in October has 25 hours, but these human meddlings with the calendar and do not correspond to the actual number of daylight hours. In Chicago, there are 15:02 hours of daylight on the summer solstice of June 21, 1999.
Here is a QuickTime movie illustrating the tilt of the Earth's equatorial plane relative to the Sun which is responsible for the seasons. The dates of maximum tilt of the Earth's equator correspond to the summer solstice and winter solstice, and the dates of zero tilt to the vernal equinox and autumnal equinox.

Your words would have been way more interesting. I felt like I was in a lecture, passing out.
