I made a thing.

It's in Dutch.
It counts down to the next year.
It should follow your browser timezone.
It's as accurate as your system time and framerate.
It's small and efficient: only a single HTML file and some GIFs.

Enjoy!

And yes, if you have a system with a framerate higher than 1000fps, then it's "only" accurate by the millisecond. Limitations of the format, unfortunately.
