Days Since Sign
The workshop sign, as a web page: it has been this many days since whatever you put in the box. The count changes at local midnight, and the full-screen mode is white on black with nothing else on it.
The sign
Shown exactly as typed. It never leaves this tab

The count, spelled out
How the days are counted, which is the only decision here
Whole days are counted between calendar dates, in your own time
zone. The number goes up at local midnight, not at the hour the thing
happened, which is how a sign on a wall behaves: nobody changes it at
09:14. The exact elapsed time is printed underneath for anyone who wants
the other reading.
A day on which the clocks change is still one day. Counting in calendar dates rather than in 24-hour blocks is what makes that true; a count of hours divided by 24 would drift by an hour twice a year and eventually show the wrong day.
A date in the future counts down rather than up, and says so. It is not an error — a sign for something scheduled is a reasonable thing to want — but it is a different sentence, so it is written differently.
The time of day is optional and only affects the exact elapsed line. With no time given the page assumes midnight, which is the convention that makes “days since” agree with the calendar.
Nothing is stored. There is no database and no cookie: the date and the label live in the address bar, which is why copying the link is how you keep a sign. Anyone you send it to sees the same sign, counting in their own time zone.
The full-screen mode drops the query string and the tab title while it is open, because both otherwise name the tool and give away the settings in a screenshot.
