Patriot Day marks September 11, 2001, when coordinated terrorist attacks killed 2,977 people in New York, Virginia, and Pennsylvania — the deadliest terrorist attack in American history, which led to the Global War on Terror, the invasions of Afghanistan and Iraq, and the most significant restructuring of American national security since World War II. Stand Up To Cancer Day is the annual broadcast event and fundraising drive organized by the Entertainment Industry Foundation, which has raised more than $1 billion for cancer research since 2008. National 401(k) Day was established by the Plan Sponsor Council of America on the Friday following Labor Day to encourage employees to review and maximize their workplace retirement account contributions. National Make Your Bed Day was created to encourage the morning habit that research — including a Navy SEAL survey published as Make Your Bed by Admiral William McRaven — links to higher productivity and a sense of accomplishment.
