The Countdown Calculator ticks down to any target date and time, to the second, and breaks the total out into plain figures — total days, total hours, total minutes — because those are the numbers you quote when someone asks how long is left.
Set a target date and time and watch a live countdown tick down to the second. The total is also broken out into plain figures — total days, total hours, total minutes — because those are the numbers you actually quote when someone asks how long is left.
A working-days count sits alongside the calendar count, which is the more useful number for a project deadline: six weeks away is thirty working days, not forty-two, and planning against the wrong one is how deadlines get missed. Dates in the past count upwards instead, turning the tool into a time-since counter for anniversaries and milestones.
The countdown ticks in real time rather than showing a static figure.
Six weeks away is thirty working days, not forty-two, and planning against the wrong one is how deadlines get missed.
Total days, hours and minutes, which is what people actually ask for.
A past date turns the tool into a time-since counter for anniversaries and milestones.
Set a date and a time, not just a date, for launches that go live at a specific hour.
Choose a date and time, or use one of the presets.
The timer updates every second, showing days, hours, minutes and seconds remaining.
The working-day figure excludes weekends, which is usually the more realistic number for a deadline.
It recalculates from the current time whenever the page is visible, so it is always accurate when you look at it, even after the tab has been in the background.
The timer switches to counting up, showing how long it has been since the date rather than stopping at zero.
Your own, taken from your device clock. If you are counting down to an event elsewhere, convert the time first with the time zone calculator.
Because weekends are roughly two days in seven. Six weeks is 42 calendar days but only 30 working days, which is a substantial difference when planning delivery.
