How the countdown works
We create December 17 at 00:00 in your local timezone for this year. If that moment has already passed, we roll to December 17 next year.
All calculations use your device clock and local timezone, so the countdown hits zero exactly when December 17 starts where you are.
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 17 to next December 17 is 365 or 366 days as appropriate.
If today is after December 17, the timer counts toward next year’s December 17 and shows how many days ago the last one occurred.
The timer is scoped to this component, accessible, and works on mobile without external libraries.
