The German-American Day is celebrated on October 06, 2017. It is a day to celebrate the German American heritage. The German-American Day is celebrated annually and commemorates the date in 1683 when 13 German families from Krefeld near the Rhine landed in Philadelphia.
These families subsequently founded Germantown, Pennsylvania, the first German settlement in the original thirteen American colonies. Originally celebrated in the nineteenth century, German-American Day died out in World War I as a result of the anti-German sentiment that prevailed at the time. The holiday was revived in 1983.
In 1983, President Ronald Reagan proclaimed October 6th as German-American Day to celebrate and honor the 300th anniversary of German American immigration and culture to the United States. (With material from: Wikipedia).
