Free Online Countdown Timer to Any Date

Whether you're counting down to a wedding, an exam, a holiday, a product launch, or the new year — our countdown timer shows you exactly how much time is left in days, hours, minutes and seconds. It updates every second in real time, right in your browser. No app to install, no account needed.

How to Use the Countdown Timer

Select your target date and time using the date picker, optionally give it a name (like "My Birthday" or "Project Deadline"), and click Start. The countdown begins immediately and continues ticking even if you leave the tab open. When the time reaches zero, a "Time's Up!" alert appears.

Frequently Asked Questions

Does the countdown timer keep running if I close the tab?
No. The timer runs in your browser and resets if you close or refresh the page. If you need a persistent reminder, we recommend setting a calendar event alongside using this timer for a visual display.
Can I count down to a specific time today?
Yes. The date-and-time picker lets you select both a date and a specific time — down to the minute. So you can count down to 3:30 PM today, for example.
How accurate is the countdown?
The countdown uses your device's system clock and updates every second. It is accurate to within one second. For critical timing (like lab experiments), always use a dedicated hardware timer.
Is this countdown timer free to use?
Yes, completely free. No sign-up, no ads shown inside the tool, and no limits on usage.
