The story

National Countdown Day is observed on March 21 each year, 3/21, a date made for counting down: 3, 2, 1. On this day we can start a countdown to just about anything, from birthdays and weddings to vacations and big launches. It is also a day to consider past and present countdowns of significance.

Read the full story

Countdowns are part of some of history's biggest moments. NASA's launch countdowns made 'T-minus' famous, and the Times Square ball drop has counted down the New Year since 1907. Whether it's a rocket launch, a championship game, or the last seconds before a wedding, counting down builds excitement and brings people together.

On National Countdown Day, pick something worth the wait and start the clock. Make a paper chain, mark off a calendar, or set a daily reminder, the countdown itself is half the fun.

As the numbers tick down, the anticipation grows, and the celebration at zero is that much sweeter. National Countdown Day reminds us that looking forward to something is one of life's great joys. So pick your moment, start counting, and enjoy every second.
