Frequently Asked Questions

1 Is the countdown affected by my browser's time zone?
The countdown uses your device's local time zone automatically. This ensures accuracy for your location, but it also means the displayed time may differ for someone in another time zone viewing a shared link.
2 What happens when the countdown reaches zero?
When zero is reached, the timer displays a celebratory message. Afterward, it starts counting upward to show how much time has passed since the event. This is useful for tracking anniversaries or how long it's been since a launch.
3 Can I save my countdown for later viewing?
Yes! Use the shareable link feature to bookmark your countdown. The URL contains all your settings, so you can revisit it anytime. No registration or login required — it's completely ephemeral.
4 Does the tool support daylight saving time transitions?
Yes. Since the timer uses your device's system clock, it automatically accounts for DST changes. The countdown remains accurate through all time adjustments, ensuring you never miss a deadline due to time changes.
5 Is my countdown data stored on your servers?
No. All countdown data is stored in your browser's memory and the URL itself. We don't have any servers or databases storing your data. Close the tab, and your countdown is gone — unless you've bookmarked the shareable link.
