About this helper

This countdown calculator runs in your browser and counts the time between now and a target local date and time. It updates every second, shows the total days and live hours, minutes, and seconds, and can copy a short event summary without uploading the date you enter.

Is my event date uploaded?

No. The countdown runs locally in your browser and the event date is not sent to Heavens Help servers.

Does the countdown use my timezone?

Yes. The date and time input uses your browser's local timezone.

Can I count past events?

Yes. If the target date is in the past, the tool shows how long ago it happened.
