I don't mean that the U.S. Constitution was thought of today for the first time, nor that it was framed today, but that today, July 2, in 1788, was the day the Congress of the Confederation (our initial government acted under the Articles of Confederation of independent states) learned that the New Hampshire ratifying committee had reconvened and had ratified the Constitution. Thus, nine states had then ratified the Constitution and that was all that was needed to make it the law of the land. It was adopted as such on this day in 1788. Of course, other states ratified it later, but it had become the law of the land as of this date, July 2, 1788. The Congress of the Confederation then started a committee to implement the new Constitutional Government. Our Constitution is the oldest working actual constitution in the histroy of the world.
All the best,
