What happens when the countdown reaches zero?

It shows "Time’s up" instead of counting into negative numbers.

Does the countdown keep running if I switch tabs?

It updates once per second while this tab is open and active; browsers may pause timers in a fully backgrounded tab, which is normal browser behavior, not a bug in this tool.

Does this tool send my target date anywhere?

No — everything runs entirely in your browser.
