From Memorial Day and Labor Day to Thanksgiving, Americans have always been willing to move the dates of major holidays around to accommodate three-day weekends and Black Friday shopping blowouts.

But the country shows no such independent streak when it comes to Independence Day. The Fourth of July falls on, well, July 4th. And everything from fireworks shows to the AJC Peachtree Road Race patriotically follows suit.

But why is that? And why did the Founding Fathers -- who managed to agree on the not-so-minor issue of splitting off from England, after all  -- not initially all agree on when Independence Day should be celebrated?

Independence Day celebrates the adoption of the Declaration of Independence in 1776.
