Frequently asked questions
How do I use the countdown timer?
Choose a target date and time in the picker. The timer immediately shows the days, hours, minutes and seconds remaining and refreshes once per second.
Which time zone does the countdown use?
The target you pick is treated as your own local time, and the countdown runs against your device clock, so both sides use the same time zone.
What happens when the countdown reaches zero?
When the target arrives the timer stops at zero and shows a Time's up message instead of the digits.
How accurate is the timer?
It updates every second and reads your device clock directly, so accuracy depends on how well your system clock is set.
Does the countdown keep running if I switch tabs?
The display catches up the moment the page is active again because the remaining time is always recalculated from the current clock, not counted manually.
Is anything sent to a server?
No. The countdown runs entirely in your browser, so the date you enter never leaves your device.
