How the countdown works
1. Next occurrence
We create December 1 at 00:00 in your local timezone for this year. If that moment has already passed, we roll to December 1 next year.
2. Local time only
All calculations use your device clock and local timezone, so the countdown hits zero exactly when December 1 starts where you are.
3. Days → seconds
Remaining milliseconds are converted to days, hours, minutes, and seconds. Values never go negative and update every second.
4. Leap years
Leap years are handled automatically by the calendar — the interval from December 1 to next December 1 is 365 or 366 days as appropriate.
5. Already passed?
If today is after December 1, the timer counts toward next year’s December 1 and shows how many days ago the last one occurred.
6. Responsive & scoped
The timer is scoped to this component, accessible, and works on mobile without external libraries.
