This is something that I find very annoying, and have noticed it getting worse year after year. The holiday to be celebrated this week is not the “4th of July” holiday, it is INDEPENDENCE DAY! We celebrate INDEPENDENCE DAY on the 4th of July. Only two signers actually signed the Declaration of Independence on July 4th. INDEPENDENCE DAY is celebrated on July 4 because that is the day when the Continental Congress adopted the final draft of the Declaration of Independence. The significance is not the date, but the Declaration of Independence itself.
The official name of the holiday is INDEPENDENCE DAY, and it is so written on the US Office of Personnel Management website: http://www.opm.gov/Operating_Status_Schedules/fedhol/2008.asp where all official federal holidays are listed.
P.S. please don’t bring up Cinco de Mayo. Most Mexicans and many people in the Southwestern states celebrate it. When you ask them what it means, most will say Mexican Independence Day. Follow up with a question, “Independence from what?” Bet you that 95% can’t tell you. It is only an excuse to party and not even an official Federal Holiday in Mexico.
