The date is in the link itself, so it works for anyone who opens it.
Pick a moment and watch it approach: days, hours, minutes and seconds, ticking live. Past dates count up instead, so the same page answers "how long since" as well as "how long until".
Alongside the clock are the totals people usually want next: the whole thing in days, weeks, hours and minutes, and the number of working days left, counting Monday to Friday from tomorrow up to and including the target. For a deadline, that last figure is the one that matters.
The share link carries the date inside it, after the #. Anyone who
opens it sees the same countdown running against their own clock, with no account
and nothing stored anywhere.
For a few minutes rather than a few months, the stopwatch and timer counts down from a duration you set and rings at zero. This page is for the date in the calendar.
How to use it
- Choose a date and time, or press one of the preset buttons.
- Give it a name if you want the heading and the shared link to say what it is.
- Copy the link to send the countdown to someone else.
Questions
How are working days counted?
Monday to Friday, from tomorrow up to and including the target date. Today is left out because it is already under way, and the deadline day is included because it is still a day you have. Public holidays are not deducted, because they differ by country and by year.
What happens when it reaches zero?
It keeps going, counting up instead. The heading switches to how long ago it was, which is what you want for an anniversary or a launch date that has passed.
Does the shared link store my countdown anywhere?
No. The date and name are in the link itself, after the #, the part browsers never send to a server. There is no database here, so the link cannot expire and nobody can see what you are counting down to.
Which time zone does it use?
Yours. The date you enter is read in your own local time, and someone opening your shared link sees it counted against theirs. For a moment that must be identical everywhere, say so in the name, or use the world clock to check what your time means elsewhere.
Why does the number of days not match my calendar?
A countdown measures elapsed time, not calendar dates: from Monday 18:00 to Wednesday 09:00 is one whole day and fifteen hours, so it shows 1 day, even though the calendar has turned twice.
