June 14, 1777. Today is Flag Day! On May 30, 1916, President Woodrow Wilson issued a presidential proclamation establishing a national Flag Day on June 14. Many Americans celebrate Flag Day by displaying the Red, White and Blue in front of homes and businesses.
Most Australians are unaware that there is such a thing as National Flag day, let alone celebrate it. Australian National Flag Day is on 3 September, our flag's birthday. The day was officially proclaimed to commemorate the day in 1901 on which the Australian National Flag was first flown. There are special flag raisings and events being held on Flag Day, but most people simply do not celebrate it.
