Saturday is Constitution Day, which commemorates the date of Sept. 17, 1787 when America's founders signed the document that created the government of the United States of America.
The 39 delegates to the Constitutional Convention in Philadelphia met for the last time to sign the document they created.
Federal law requires public schools to observe Sept. 17. Since the anniversary falls on a Saturday this year, the holiday is observed on Friday, Sept. 16.
However, a group known as Wallbuilders says studies show most schools ignore the law.
The group is reminding schools and families to take the time to learn more about the U.S. Constitution.
Wallbuilders points out the Constitution is full of religious principles, and the founders who wrote it specifically acknowledged God in its creation.
When the Constitution was signed, it gave the power of government to the people, which was not too common an idea in the 18th century's time of kings and nobles.
As the document states in the preamble:
"We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America."
