Countdown Timer
Count down to any date and time, live. Runs entirely in your browser. Nothing you type is ever uploaded.
What can you do?
DaysUntil counts down live to any date and time you pick. A birthday, a deadline, a launch, a holiday. With a running days/hours/minutes/seconds breakdown that updates every second while the page is open.
Ever notice a countdown "jump" when you switch back to its tab? Read How Browsers Keep a Countdown Accurate in a Background Tab.
How it works
The countdown runs directly in your browser against your device's own clock. Nothing is sent to a server, so it works even offline once the page has loaded.
Frequently asked questions
Is this free to use?
Yes. There's no sign-up and no limit on how many countdowns you set.
Do you store what I type?
No. The countdown runs entirely client-side using your device's clock, and nothing you enter is uploaded or stored. See the privacy policy for details.
What timezone does the countdown use?
Your device's local timezone. The target date and time you pick is treated as local time, and the countdown updates live against your device's own clock.
Does the countdown keep running if I close the tab?
No. It only runs while the page is open. Bookmark the page and reopen it any time to see the current countdown recalculated fresh.
