Frequently Asked Questions
Can I save a countdown for future reference?
Share the countdown URL — it encodes your target date and title in the URL parameters so anyone with the link sees the same countdown. Bookmark the page to return to your countdown later.
What happens when the countdown reaches zero?
The timer displays "Time's up!" with a visual alert. An audio chime plays if your browser has notification permissions granted. The timer switches to count up from zero after the target time passes.
Can I create a countdown for a time in a different time zone?
Enter the event's local time and the tool converts it relative to your browser's current time zone. If the event is in a different time zone, convert the time first using the Time Zone Converter tool.
Can I use this as a presentation timer?
Yes. Enter a time X minutes from now as your target, or use the optional "Count down from duration" mode to set a timer for a specific number of minutes directly (like a kitchen timer or presentation slot).
Does the timer continue counting if I close the tab?
The timer is re-synced with the system clock each time you open the page. Closing and reopening the tab shows the correct remaining time based on the current date vs your target date — it doesn't "stop" while the tab is closed.

Yes, the Countdown Timer on Allio Tools is completely free with no sign-up or registration required. It works directly in your browser.
