How the countdown works
We create October 15 at 00:00 in your local timezone for this year. If that moment has already passed, we roll to October 15 next year.
All calculations use your device clock and local timezone, so the countdown hits zero exactly when October 15 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 October 15 to next October 15 is 365 or 366 days as appropriate.
If today is after October 15, the timer counts toward next year’s October 15 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.
