September 6 is:
Fight Procrastination Day
Read a Book Day…Isn’t that every day?
National Coffee Ice Cream Day
Coffee is only grown near the equator, from the Tropic of Cancer to the Tropic of Capricorn, within a 1,000 mile limit.

The Tropic of Cancer and the Tropic of Capricorn each lie at 23.5 degrees latitude. The Tropic of Cancer is located at 23.5 degrees north of the equator and runs through Mexico, the Bahamas, Egypt, Saudi Arabia, India, and southern China. The Tropic of Capricorn lies at 23.5 degrees south of the equator and runs through Australia, Chile, southern Brazil (Brazil is the only country that passes through both the equator and a tropic), and northern South Africa.
The tropics are the two lines where the sun is directly overhead at noon on the two solstices—about June 21 and December 21. The sun is directly overhead at noon on the Tropic of Cancer on June 21 (the beginning of summer in the Northern Hemisphere and the beginning of winter in the Southern Hemisphere), and the sun is directly overhead at noon on the Tropic of Capricorn on December 21 (the beginning of winter in the Northern Hemisphere and the beginning of summer in the Southern Hemisphere).
The reason for the location of the Tropic of Cancer and the Tropic of Capricorn at roughly 23.5 degrees north and south, respectively, is due to the axial tilt of the Earth. The Earth is tilted 23.5 degrees from the plane of the Earth’s revolution around the sun each year.
The area bounded by the Tropic of Cancer on the north and Tropic of Capricorn on the south is known as the “tropics.” This area does not experience seasons, because the sun is always high in the sky. Only higher latitudes, north of the Tropic of Cancer and south of the Tropic of Capricorn, experience significant seasonal variation in climate. Areas in the tropics can be cold, however. The peak of Mauna Kea on the Big Island of Hawaii stands nearly 14,000 feet above sea level, and snow is not unusual.
If you live north of the Tropic of Cancer or south of the Tropic of Capricorn, the sun will never be directly overhead. In the United States, for example, Hawaii is the only location in the country that is south of the Tropic of Cancer, and it is thus the only location in the United States where the sun will be directly overhead in the summer.
Puritans settled Salem in 1628. It will later become part of Massachusetts Bay Colony.
Birthday of Gilbert du Motier, Marquis de Lafayette (September 6, 1757), French aristocrat and military officer who became a general in the American Revolutionary War and a leader of the Garde nationale during the French Revolution.

September 6, 1901: US President William McKinley 
was shot by anarchist Leon Czolgosz at Pan American Exposition in Buffalo NY. Two shots were fired. The first deflected off a button and was easily found and removed. The second however was fatal. The newly-developed X-ray machine was displayed at the fair, but doctors were reluctant to use it on McKinley to search for the bullet because they did not know what side effects it may have had on him. Also, ironically, the operating room at the exposition’s emergency hospital did not have any electric lighting, even though the exteriors of many of the buildings at the extravagant exposition were covered with thousands of light bulbs. Doctors used a pan to reflect sunlight onto the operating table as they treated McKinley’s wounds. McKinley eventually went into shock. He died from his wounds early on the morning of September 14th.
