Questions
How accurate is the countdown?
The countdown updates every second and uses the system clock, so it is accurate to within one second.
What happens when the countdown reaches zero?
The timer stops and displays that the target date has been reached.
Can I set a countdown timer for a specific time and timezone?
Enter both the date and time for your target event. The countdown calculates against your local system time, so the result reflects your current timezone automatically.
Does the countdown timer keep running if I switch browser tabs?
Yes. The timer uses the system clock to calculate the remaining time on each tick, so it stays accurate even if the tab is in the background and updates are throttled.
Is the countdown timer private?
Yes. The target date and countdown run entirely in your browser. No data is stored on a server or shared with anyone.
