The Countdown & Days Until Calculator shows exactly how long until any date — with a live timer counting down the days, hours, minutes, and seconds. Pick a birthday, exam, wedding, festival, or deadline and watch the countdown tick in real time.
You can also enter a past date to see how long ago it was. Add an optional time for an exact-to-the-second countdown, or use a quick preset. Everything runs in your browser using your device’s clock.

Frequently Asked Questions
How many days until a specific date?
Enter the date and the calculator instantly shows the number of days remaining, along with a live countdown in days, hours, minutes, and seconds.
Does the countdown update in real time?
Yes. It refreshes every second using your device’s clock, so the hours, minutes, and seconds tick down live while the page is open.
Can I count down to a specific time of day?
Yes. Use the optional time field to set an exact time (for example an exam at 09:00), and the countdown will be accurate to the second.
Can I see how many days have passed since a date?
Yes. Choose a date in the past and the tool shows how long ago it was, in days, hours, minutes, and seconds.
Is it accurate across time zones?
The countdown uses your own device’s local time, so it matches the clock on your device. If you need the difference between two fixed calendar dates, use our Date Difference Calculator.
