How the countdown works
We create September 19 at 00:00 in your local timezone for this year. If that moment has already passed, we roll to September 19 next year.
All calculations use your device clock and local timezone, so the countdown hits zero exactly when September 19 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 September 19 to next September 19 is 365 or 366 days as appropriate.
If today is after September 19, the timer counts toward next year’s September 19 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.
