Countdown Timer

How to use this countdown timer

Pick any future date and time, optionally give it a title, and the timer instantly starts counting down in days, hours, minutes, and seconds updating live as you watch. Keep the tab open to track it in real time, or check back any time to see how much time is left.

What a countdown timer is for

A countdown timer counts down to a specific date and time you choose a product launch, a wedding, a conference talk, an exam start, a livestream, or a holiday. Unlike a simple minute timer, this one lets you target an exact calendar date and time months or even years out, and it recalculates the days, hours, minutes, and seconds remaining continuously as you watch.

Countdown timer vs. stopwatch vs. pomodoro timer

These three tools solve different problems. A countdown timer counts down to a fixed future date and time, like this page. A stopwatch counts up from zero with no set end point, for open-ended timing. A Pomodoro timer counts down in short, fixed work/break intervals designed for focus sessions. If you know the exact date and time you're counting down to, this is the right tool.

How the remaining time is calculated

The countdown compares the current moment to the target date and time you entered and breaks the difference into days, hours, minutes, and seconds, updating once per second. Because it recalculates from the actual clock rather than just ticking a number down, closing and reopening the page or leaving it running for days never introduces drift; the display is always exactly correct for wherever "now" is at that instant.

Common uses

Event organizers use it to build anticipation on a landing page before a launch or sale. Teachers and test proctors use it to display remaining exam time on a projector. Students and professionals use it to track how much runway is left before a deadline. Because you can give it a title, it also works well as a simple "time until X" display for a presentation slide or waiting room screen.

FAQ

Does the countdown keep running if I close the tab?
No the countdown only runs while the page is open. Reopening the page will recalculate the time remaining based on the date you entered, as long as you keep the same date selected.

Can I count down to a date in the past?
If the selected date has already passed, the timer will show that the countdown has ended.

How is this different from a stopwatch?
A stopwatch counts up from zero and has no target end time you start it and watch time accumulate. This timer does the opposite: you set a target date and time, and it counts down to that exact moment.

Can I give the countdown a name?
Yes the optional event title field displays above the countdown, which is useful if you're projecting it during a presentation or sharing a screenshot.

Does it show seconds, or just minutes?
It shows days, hours, minutes, and seconds, all updating live once per second, so you can watch the exact moment it reaches zero.

Can I use this for multiple events at once?
This tool tracks one countdown per browser tab. To track more than one event at a time, open the page in additional tabs, each with its own date and title.
