How Many Days Since?
I looked online. I found a few sites that did what I wanted. None of them worked well on mobile.
I wanted to know how many days it had been since a given date... so here it is: How Many Days Since?. It's not fancy. It only has one page. But it does what I needed on all my devices... including using pushState to make the URL bookmarkable.
Sometimes a need is simply something a first semester web student can do. But I wanted one with a little bit of style, so with just a quick CodePen and a push to my server I now have one that suits my exact need... and maybe yours, too.
