Countdown to Date

A free live countdown to any date or event, with days, hours, minutes and seconds, a fullscreen mode, and a shareable link. Runs in your browser.

🌐 Español

New Year

123days
23hours
18minutes
58seconds

The share link encodes your date, time and title right in the URL — anyone who opens it sees the exact same countdown, with nothing sent to any server.

🔒 Private by design: everything runs locally in your browser and never uploaded to any server.

Two fields, and the defaults the page opens on

There is no file to upload and no settings panel here, just a text box labeled Event or holiday name and a native picker labeled Date & time. Before you touch either, the page has already picked something for you: the next 1 January at local midnight, titled New Year. That default exists because the most searched version of this question is a holiday, and an empty countdown is a useless first impression.

The picker works in your own local time, which is the right choice for a field you are typing into directly. The share link, as you will see below, does the opposite.

Underneath, four numbers tick over once a second. Days are printed as they come, while hours, minutes and seconds are padded to two digits, so 7 days, 04 hours, 08 minutes and 33 seconds holds a steady width instead of shuffling sideways every time a number drops below ten.

Setting a countdown up and putting it on a screen

  1. Type into Event or holiday name. A birthday, a launch, a deadline, a wedding, anything you would otherwise be counting on your fingers.
  2. Set Date & time with the picker. Both the date and the time of day matter, since the countdown resolves down to the second.
  3. Watch the four numbers. They recompute from the current clock on every tick rather than counting down an internal number, so they cannot drift, and a tab that has been asleep in the background snaps straight back to the correct value when you return to it.
  4. Click Fullscreen to fill the screen with the countdown, which is what you want on a projector, a spare monitor or a stream overlay. The same button then reads Exit fullscreen.
  5. Click Copy share link to put the whole countdown on your clipboard as a URL. The button confirms with Link copied! when it worked.

If your browser refuses clipboard access, the tool says so and points you at the address bar instead, which is a real fallback rather than a dead end.

This site is static, so there is no database in which to park a shared countdown, and it turns out none is needed. The date and the title travel inside the URL itself. Paste that link into a group chat or an event page and everyone who opens it lands on the same live countdown, with no account, no short-link service and nothing kept on any server.

The target is encoded as a UTC timestamp on purpose. The picker you typed into is local, but the person opening your link may not share your time zone, and an absolute instant is the only version of “8pm on Friday” that survives the trip. The event name rides along as a second parameter, left out entirely when you have not set one.

Elapsed time, not calendar squares

The countdown is pure millisecond arithmetic, which is worth understanding before you argue with it. Ask Days Between Dates Calculator how far away a date is and you get whole calendar days between two dates, with a business-day count if you want one. Ask this page and you get how much time is actually left, which is a different quantity across a daylight-saving boundary. From midday on 1 August 2026 to midnight at the start of Christmas Day that same year, this tool shows 145 days and 13 hours in a zone that ends summer time in between, and 145 days and 12 hours in one that has no such change.

At zero, the display stops rather than going negative

When the target passes, the four numbers are replaced by a short “it’s here” message, and that is all that happens. There is no alarm sound, no browser notification and no confetti. A countdown that keeps ticking into negative numbers is confusing rather than useful, so it stops, and the tool does not pretend to still be running.

That also means this is the wrong page for anything you need to be woken up by. Online Timer and Stopwatch counts down a duration you set rather than a date on the calendar and does have a sound alarm, and it keeps a stopwatch and Pomodoro presets alongside it. If the event belongs in a calendar rather than a browser tab, ICS File and Add to Calendar Link Generator builds a proper .ics file plus Google and Outlook links, so the reminder comes from the calendar app that is already going to nag you.

Where the countdown lives between visits

Every edit to the name or the date is written to your browser’s local storage, so coming back to the page later picks up where you left off instead of resetting to New Year. A share link always beats that saved copy on load, and then replaces it. Nothing is synchronized anywhere, so a countdown you set on a laptop will not appear on your phone unless you send yourself the link.

If you are announcing the date somewhere else as well, Discord Timestamp Generator turns the same moment into the codes Discord renders in each reader’s own time zone, which pairs neatly with a shared countdown. The other live widgets on this site are collected under testers and walked through in our guide to the hardware testers and widgets here.

Frequently asked questions

Can I keep an eye on the countdown while I work in another tab?

Yes, because the browser tab's own title is rewritten on every tick. It shows an hourglass, the remaining time in a compact days/hours/minutes/seconds form, and then your event name, so a glance at the tab strip is enough. Once the moment arrives the title switches to a short "is here" message with your event name in it. Navigating away from the page puts the original title back.

What exactly is stored inside the share link?

Two query parameters and nothing else. The target moment is written as a full ISO timestamp in UTC, which is what makes the link safe to send to somebody in another time zone, and your event name is written as a second parameter that is left out entirely if you cleared the field. The link is built from the page address without any query string it already had, so forwarding a shared link never stacks parameters on top of each other.

A friend opened my link on a machine that already had a countdown saved. Which one wins?

The link. On load the page reads the address bar first and only falls back to the saved copy when there is no usable target parameter there, which is the only sensible order for something meant to be shared. Opening the link then overwrites what was saved, so the visitor keeps your event rather than theirs. A malformed or truncated link is ignored rather than throwing an error.

Why does the day count sometimes disagree with what I get by counting squares on a calendar?

Because this counts elapsed time rather than calendar dates. The gap is measured in milliseconds and then divided into days, hours, minutes and seconds, so a stretch that crosses the end of daylight saving genuinely contains an extra hour of real time. Counting from midday on 1 August 2026 to Christmas Day gives 145 days and 13 hours in a zone that puts its clocks back, and 145 days and 12 hours in one that does not. Neither number is wrong; they measure different things.

Where does my saved event live, and how do I get rid of it?

In your browser's local storage under a key belonging to this page, written again every time you edit the name or the date. It is per browser and per device, so it does not follow you to your phone, and clearing your site data removes it. If storage is unavailable, which is common in private browsing, the write is skipped silently and the countdown still runs normally for the session.

What shows up if I leave the event name blank?

The heading above the digits falls back to New Year, which is also the default event the page starts on, together with the next 1 January at local midnight. The tab title behaves slightly differently and falls back to the name of this tool instead. The field itself accepts up to 80 characters, which is enough for a sentence but not a paragraph.
