Days
Live countdown to any future date, minute, hour or event.
This countdown timer takes any future date and time you choose, names it, and then ticks down live in days, hours, minutes and seconds until that moment arrives. It's the same idea as the big countdown clocks you see for product launches, conferences or New Year's Eve, but you can point it at literally any date and it runs entirely inside your browser tab.
Rather than simply decrementing a number every second, the timer recalculates the remaining time from scratch on every tick by comparing your target date and time to the current system clock. That means the countdown is always exactly correct even if your laptop goes to sleep, the browser tab is backgrounded for a while, or the page has been open for hours — there's no drift from repeatedly subtracting one second at a time.
Teams use countdowns to keep everyone aligned on a launch date or deadline, event organizers use them to build anticipation on a landing page, and individuals use them for anything from a wedding date to the start of a vacation. Because you can label the event yourself, the same tool works whether you're counting down to a conference keynote, a college application deadline, or a rocket launch window.
Once the target moment passes, the timer stops updating the day/hour/minute/second grid and instead shows a simple message that the event has arrived. If you want to count down to a different moment afterward, just change the date and time and submit the form again — the previous countdown clears immediately.
A countdown feels different from a static 'days remaining' number because it's visibly alive — the seconds ticking over reinforce that the event is real and approaching, which is part of why countdowns are so often used for big public moments as well as personal ones. Keeping the tab open in the background costs nothing, since the display recalculates from the real clock every second rather than relying on the tab staying continuously active.
Yes. Because the remaining time is recalculated from the current clock on every tick rather than just being decremented, it stays accurate even after the tab has been inactive for a while.
You can enter any date and time, but if it's already in the past the countdown will immediately show that the event has already happened, since there's no remaining time to count down.
It uses your device's local timezone, both for entering the target date/time and for the running clock, so the countdown always reflects your own local time.
This page runs one countdown at a time. If you need to track several events, open the tool in separate browser tabs, one per event.
No practical limit — you can set a target decades away and the timer will simply show a large number of days remaining.
