Free Custom Countdown Timer

What CountdownClock.net does

CountdownClock.net turns a date into a link. Type what you are counting down to, pick the moment it happens, and you get a URL that shows a live clock ticking toward it. Open that link on a phone, a laptop or a projector at the front of a room and the numbers agree, because the clock is calculated from the target time rather than from a session that begins when the page loads. Close the tab, come back a week later, and it is still counting.

There is no account, nothing to install and no cap on how many countdowns you create. The link is the product: text it, put it in an email, pin it in a group chat, or drop it into a page of your own as an embedded clock. Switch the direction and the same page counts up instead, measuring time elapsed since a date that has already passed — useful for sobriety dates, anniversaries, uptime, or anything else you would rather count forward from.

How to create one

The form above is the whole process. It takes about thirty seconds:

1. Name it. Whatever you type appears above the clock — "Launch day", "Grandma arrives", "Quiz ends in". Leave it blank and you get a bare clock.
2. Set the date and time. The picker uses your device’s local time zone, and the countdown is stored as an absolute moment, so somebody opening your link in another time zone sees the same amount of time remaining rather than a different clock.
3. Choose a direction. Count down to a future date, or count up from a past one.
4. Pick a theme. Five of them, from high-contrast black to a light theme for bright rooms. The preview below the form updates as you change it, so you are never guessing at what the finished clock looks like.
5. Create it, or copy the link. "Create" opens the clock full screen. "Copy link" puts the URL on your clipboard without leaving the page.

Who this is built for

• People counting down to a date that matters — a wedding, a due date, a move, a release, a retirement, the last day of school. This is the most-used part of the site and the reason the form sits at the top of this page.
• Sports fans — our NFL, college football, basketball and soccer pages carry a live countdown to each team’s next fixture, so you never have to look a kickoff time up and type it in yourself.
• Teachers — the classroom timer and the fixed-duration timers are built to be legible from the back of a room and to open full screen in one click.
• Site owners and organisers — every countdown can be embedded as an iframe, so an event page can carry a live clock without anyone writing timer code.

Countdowns already built for you

Some things get counted down to over and over, so we build those ahead of time rather than making everybody construct them by hand. Holiday countdowns recalculate themselves each year and roll forward to the next occurrence the moment one passes. Days Until answers the plain question for hundreds of events. Time Since counts up from historical moments — the moon landing, the end of the Second World War — which is where the history and science classroom traffic tends to land.

Every league page pulls its own fixtures and shows the next game for each team. Where each published date comes from is documented on our data sources page.
