Frequently Asked Questions

How do I count down to an event?

Pick the target date and time in the date-time box — the display ticks live in days, hours, minutes, and seconds. Weddings, launches, exams, and deadlines all work the same way.

Does it handle timezones?

No — the target uses your browser's local time with no timezone picker. Enter the event time in your own zone; travelers should re-enter it after changing zones.

Will it keep running if I close the tab?

No — closing the tab stops the countdown and nothing persists. Reopen the page and press Start Countdown again; it recomputes from the entered date.

Can I share the countdown?

No — there is no shareable link; the target lives only in your open tab. Recipients must enter the same date on their own devices.

When using Countdown Timer, is anything uploaded?

No. Everything runs locally in your browser. Nothing leaves your device.
