Days Until Calculator
See exactly how many days and hours remain until any future date.
Pick a target date to see how long is left.
The remaining time updates live from your device’s clock. With no time set, the count runs to the start of the target day in your local timezone; once the moment passes, it shows how long ago it was. Nothing is uploaded.
How to count the days until a date
Pick a target date — and optionally a time. The number of days and hours remaining appears immediately and keeps ticking down on its own. Change the target at any point to count toward something else.
What to count down to
A holiday, a birthday, an exam, a product launch, a wedding or the end of a trial. Because it updates live, you can leave the tab open as a small running countdown.
Questions
Does the count update on its own?
Yes. The remaining days and hours refresh live from your device's clock, so the figure stays current the whole time the page is open without you reloading.
What happens once the target date passes?
When the target moment has gone by, the tool flips to show how long ago it was instead of a negative number, so you always see a clear, readable result.
Is the target counted to midnight or to a time?
If you set only a date, the countdown runs to the start of that day in your local time. You can pick a specific time too for an exact to-the-hour count.
