5 things to know about Flag Day

Flag Day is celebrated annually in the U.S. on June 14. Here are some key things to know about the holiday.

How did Flag Day originate?

Flag Day has a long history and began on the local level. Its origins date back to 1885, when a schoolteacher in Wisconsin had his class honor "Flag Birthday" on June 14 to mark the anniversary of the Flag Resolution of 1777. From there, communities across the country began to mark the day, according to americaslibrary.gov. On that day, June 14, 1777, John Adams spoke about the flag at a meeting of the Continental Congress in Philadelphia.

"Resolved, that the flag of the thirteen United States shall be thirteen stripes, alternate red and white; that the Union be thirteen stars, white on a blue field, representing a new constellation,” Adams said during the meeting.

2.) When did Flag Day become a national holiday?

On May 30 1916, President Woodrow Wilson made a presidential proclamation, which officially established Flag Day, according to americaslibrary.gov. It was not until 1949, however, that President Harry Truman signed an act of Congress designating June 14 as Flag Day.
