Where the World Gathers to Celebrate Every Day

National Countdown Day - March 21


3…2…1…National Countdown Day on March 21 ticks down the minutes, seconds or days to events big and small.

3…2…1…July 16, 1969, Apollo 11 launches into the atmosphere carrying the crew for the first moon landing.

3…2…1…Y2K, everyone partied like it was 1999 until the new millennium arrived.

3…2…1…it’s 5 o’clock somewhere!

On National Countdown Day, 03/21, we can start a countdown to just about anything. Around the office, it’s a countdown to the next celebration every day! Consider past and present countdowns of significance.

Recently parts of the United States counted down to August 21, 2017, to a total solar eclipse. The event created road trip opportunities for those within driving distance and science party lessons on rooftops in the path of the eclipse. It was a memorable countdown, indeed.  Did you miss it? Start your countdown for April 8, 2024. This solar eclipse will cover parts of Mexico, Central and Northeastern United States and just a bit of Canada.


Countdowns to royal weddings draw a lot of attention. The fanfare and commitment to tradition remind us of storybook weddings. There are several royal weddings to recall; Prince Charles and Lady Diana Spencer on July 29, 1981; Prince William and Catherine Middleton, April 29, 2011; Prince Harry and Meghan Markle on May 19, 2018.

Another British countdown that keeps the world interested is the countdown to Brexit. Or is it not it?


Some favorite U.S. countdowns in the U.S. are countdowns to opening day – this could be the opening day of baseball, racing, the swimming pool or hunting season.  The countdown to tax day, election day, or even the closing bell can be a positive or ominous one. It all depends on the outcome and sometimes one depends on the results of the other countdowns!


Countdowns to summer break may be started as early as September 1 or as late as spring break.  Those who motor on two wheels like to countdown to Sturgis and sports enthusiasts have countdowns to March Madness, Gameday, and Olympic Opening Ceremonies.
