About the Countdown Timer
The Countdown Timer shows a live, ticking count of the days, hours, minutes and seconds remaining until any date and time you choose. Use it to build anticipation for a birthday, wedding, product launch, exam, holiday or New Year — the numbers update every second while the page is open.
How to use it
Enter an optional event name, pick a target date and time, then press Start countdown. The timer immediately begins counting down in real time using your device's local clock and time zone. When it reaches zero, a celebratory message appears.
Countdown vs days-until
A countdown timer ticks second-by-second and is best for a live page or a near-term event. If you only need the whole-day figure — "how many days until" — the Days Until Calculator gives a cleaner summary in days, weeks and months.
Frequently Asked Questions
Does the countdown keep running if I close the tab? The display pauses when the tab is closed, but it recalculates from the real clock the moment you reopen it — so it is always accurate.
What time zone does it use? Your device's local time zone. Two people in different zones counting to the same local time will see different remaining times.
Can I count down to midnight? Yes — set the time to 00:00 on the target day for a classic midnight countdown.
