This is a simple New Year Countdown that works for any year! It has fireworks effects (when the countdown reaches 0) and a smooth number slider (you have to see it, I used NumberFlow for it).

From a developer perspective, it is performant (I used Next.js), responsive, and simple.

The code is open source here:
