11.September
Hardly anyone is unfamiliar with the term 9/11.
In the United States, Patriot Day occurs on September 11 of each year in memory of the people killed in the September 11 attacks of the year 2001.
In memory of 2,977 victims and of terrorattacks, since 2002 this day has been celebrated as a silent holiday. On the direction of the President, the flag of the United States of America should be displayed on the homes of Americans, the White House and all United States government buildings in the whole world. The flag should be flown at half-staff as a mark of respect to those who died on September 11, 2001. Many people observe a moment of silence at 8:46 AM (Eastern Daylight Time). This marks the time that the first plane flew into the World Trade Center. Some communities, particularly in the areas directly affected by the attacks, hold special church services or prayer meetings. People who personally experienced the events in 2001 or lost loved ones in them, may lay flowers or visit memorials. Patriot Day is not a federal holiday and schools and businesses do not close.
September 11, 2001, changed more than the skyline of New York City - the attacks changed a generation of Americans.
It is not just for Americans a special day, it is a day that no one will forget.
It is considered the day that changed the world.
