We create December 31 at 00:00 in your local timezone for this year. If that moment has already passed, we roll to December 31 next year.

Remaining milliseconds are converted to days, hours, minutes, and seconds. Values never go negative and update every second.

Leap years are handled automatically by the calendar — the interval from December 31 to next December 31 is 365 or 366 days as appropriate.
5. Already passed?
If today is after December 31, the timer counts toward next year’s December 31 and shows how many days ago the last one occurred.
6. Responsive & scoped
