Countdown Timer to Any Date
Count down to a launch, a wedding, a deadline or a holiday. Watch the days, hours, minutes and seconds fall in real time, then copy a clean widget to drop the countdown onto your own site.
Pick a target date and time to start a live countdown and generate an embeddable widget.
How the countdown works
Pick any future date and time and the timer works out the exact gap to that moment, updating once a second so the seconds visibly tick down. When the moment arrives the display flips to counting up, which keeps event pages sensible after the deadline has passed.
The embed is where the countdown becomes portable. When you set a target, the tool builds an iframe snippet pointing at a lightweight widget page with the target moment baked into the link. Paste that snippet anywhere HTML is allowed and the live counter travels with it, no scripts and no setup.
Time zones done right
The target instant is converted to UTC before it goes into the embed link. That means the countdown is anchored to a single point in time, so a viewer in Tokyo and a viewer in New York both see the counter reach zero at the same real-world moment, even though their local clocks read differently.
Good uses for an embeddable countdown
A live countdown is a natural fit for product launch pages, sale deadlines, conference and webinar sign-ups, wedding and event sites, and community goals. Because the widget is a plain iframe, it works on static sites, blog platforms and most content management systems without any extra plugins.
What a daylight saving change does to a countdown
A countdown to a moment and a countdown to a date are not the same thing, and the difference shows up whenever the clocks change between now and the target. This tool counts down to an instant, so the day figure is the number of whole 24-hour blocks remaining, not the number of calendar days.
| Situation | What happens |
|---|---|
| Clocks go forward between now and the target | One day in that stretch is 23 hours long, so the countdown reaches zero an hour earlier by the wall clock than a plain day count would suggest. |
| Clocks go back between now and the target | One day is 25 hours, so there is an extra hour to run. |
| Your visitor is in another time zone | The target is read against their local clock, so a countdown to "1 January, midnight" ends at their midnight, not yours. That is usually what people want from a New Year counter and almost never what they want from a product launch. |
| You need one shared moment worldwide | Set an explicit time and say which zone you mean in the label, for example "Launch, 15:00 UTC". A countdown alone cannot carry that information. |
The holiday pages in the countdown directory work the other way round on purpose: a holiday is a calendar date rather than an instant, so those counters resolve against each visitor's own midnight. Christmas is 25 December wherever you are.
Frequently asked questions
How do I add a countdown timer to my website?
Set a target date and time above, then copy the iframe snippet that appears and paste it into your page's HTML. The widget is self-contained and starts ticking down immediately for every visitor.
Does the embedded countdown work across time zones?
Yes. The target moment is stored in UTC inside the embed link, so everyone who views the widget counts down to the exact same instant, no matter where they are.
Is the countdown accurate to the second?
Yes. Both the on-page timer and the embedded widget update once per second, showing days, hours, minutes and seconds remaining until the target.
What happens when the countdown reaches zero?
The timer switches to counting up from the target and shows a reached label, so a launch or event page keeps making sense after the moment passes.
Do I need an account to use the countdown?
No. There is no sign-up and nothing to install. The tool runs in your browser and the embed is a plain iframe with no scripts to add to your site.
Ready to put this on your own site? The embed page has a live builder, three sizes and the code to copy. Counting to a holiday instead? Every one in the directory already has a page, with its dating rule and the next ten years.
