How many days until National Countdown Day?


We often count down before New Year's Eve, before the transition between the old year and the New Year. At that time, the sounds of the night backwards 3...2...1...will be chanted by everyone in unison so that the time will be transferred. And the word Countdown is often used to refer to events, programs, and festivals that count down in important moments. Because of that, National Countdown Day is held annually on March 21 every year, aiming to help us start counting down anything around our daily lives. National Countdown Day is also an opportunity for us to consider the meaning of countdown past as well as present.

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

3… 2… 1. On January 19, 2013, Marlo Anderson quietly launched a website called National Day Calendar.

Everything can count down on this day.
