Frequently asked questions
How does the Countdown Calculator work?
Choose the date and time you are waiting for and the tool counts down live — days, hours, minutes and seconds — using your device's clock.
Can I count down to a time, not just a date?
Yes. The picker includes the time of day, so you can count down to an exact moment like the start of an exam or a flight.
What happens when the countdown reaches zero?
The display stops at zero and tells you the moment has arrived. Past dates show a message instead of a negative countdown.
Is it free?
Yes — completely free, no sign-up, and it keeps working even if you leave the tab open in the background.
