A live countdown of days, hours, and minutes to any custom date.
Enter a target date and time to start the countdown.
This is a general-purpose countdown to any custom date and time you choose -- a wedding, a launch, a vacation, a deadline -- updating automatically as time passes rather than requiring a page refresh.
Enter a target date and time. The result shows days, hours, and minutes remaining, refreshing on its own roughly once a minute.
Remaining time = target timestamp - current timestamp, in milliseconds, then decomposed into whole days, hours, and minutes. Once the target time passes, the countdown reports the event has occurred rather than showing a negative countdown.
A target 2 days and 5 hours away shows 2d 5h remaining, updating live as time passes.
For a countdown specifically to a recurring event's next occurrence, see the Next Occurrence Calculator. For an appointment-specific reminder time, use the Appointment Reminder Calculator.
Suppose it is currently Monday at 9:00 a.m. and you set a target of Thursday at 3:30 p.m. The difference is 3 days, 6 hours and 30 minutes, which the tool shows as days, hours and minutes. As the minutes tick by the display refreshes about once a minute, so it can lag the true time by up to a minute, and it does not show seconds.
The target is read in your browser's local time zone. If you are counting down to something that happens in another city, such as a webinar in another region, convert the start time to your own time first, or the countdown will be off by the difference between the zones. Also confirm AM versus PM and the date, since a wrong choice on either shifts the result by half a day or more.
The math is done on actual elapsed milliseconds between now and the target. If a daylight saving change occurs between now and the target, the countdown reflects real elapsed time, so the result might differ by an hour from what you get by counting wall-clock days. For instance, a target at 9:00 a.m. exactly 7 calendar days away could be 167 or 169 real hours out if the clocks change in between. That is correct behavior, but it can be surprising.
When the target time arrives, the tool stops counting down and shows that the event has passed instead of a negative figure. If you enter a target that is already in the past, you will see the passed state immediately. Reload the page or choose a new target to start again.
A countdown is helpful for personal deadlines, such as an application closing time, a lease end date, or a shipping cutoff. When the deadline is measured in business days rather than exact moments, a business-day tool is a better fit, because a countdown counts every calendar hour including weekends and nights.
Because the countdown runs in an open browser tab, a sleeping device or a background tab can delay updates until the page becomes active again. When it does, the value catches up to the real time immediately, since it is calculated from the current clock rather than counted down from a stored number. For anything with legal or financial consequences, such as a filing deadline, confirm the exact deadline and time zone with the official source instead of relying on a browser countdown.
Yes -- it refreshes roughly once a minute without needing a manual page reload.
The tool shows that the event has passed instead of a confusing negative countdown.
The target time is read in your browser's local time zone -- make sure to enter the target in your own local time, or convert it first with the Time Zone Converter.
The tool reports days, hours and minutes and refreshes about once a minute, so seconds are not displayed.
No. The value is computed from the current clock each time it refreshes, so it corrects itself when the page becomes active again.
Convert the event's start time to your local time first and enter that, because the target is interpreted in your browser's time zone.
