Recently I learned why the flag is folded 13 times and what the 21 gun salute means. Sorry to say, I didn't know all of this.
The 21-gun salute at funerals stands for the sum of the numbers in the year 1776.
Folding the Flag: Summarized by me
1st fold: Symbol of life.
2nd fold: Symbol of belief in eternal life.
3rd fold: In honor and remembrance of veterans departing the ranks who gave a portion of their lives for defense of our country to attain world peace.
4th fold: Need to turn to our trust in God, in times of peace or war, for His divine guidance.
5th fold: Tribute to the country--"it is still our country right or wrong." (Stephen Decatur--Stephen Decatur Jr. was a United States naval officer and commodore. He was born on the eastern shore of Maryland in Worcester County, the son of a U.S. naval officer who served during the American Revolution.) Wikipedia
6th fold: Where people's heart lie. It is with their heart that they pledge allegiance to the flag of the United States of America, and the Republic for which it stands, one Nation under God, indivisible, with Liberty and Justice for all.
7th fold: A tribute to the Armed Forces protecting country and flag against all her enemies
8th fold: A tribute to the one who entered into the valley of the shadow of death, that we might see the light of day.
9th fold: a tribute to womanhood, and Mothers.
10th fold: A tribute to the father.
11th fold: the lower portion of the seal of King David and King Solomon and glorifies in the Hebrews eyes, the God of Abraham, Isaac and Jacob.
12th fold: Represents an emblem of eternity and glorifies, in the Christians' eyes, God the Father, the Son and Holy Spirit.
13th fold: Completely folded. The stars are uppermost reminding them of their Nations motto--In God We Trust.
After the flag is completely folded and tucked in, it has the appearance of a cocked hat, ever reminding us of the soldiers who served under Gen. George Washington and the sailors and Marines who served under Capt. John Paul Jones and were followed by their comrades and shipmates in the U.S. Armed Forces, preserving for us the rights, privileges and freedoms we enjoy today.
