Ok I checked in a version where you should be able to search by the standard Q date format.

e.g.

"nov 11 2019"

"nov 11"

"NOV 11"

"nov 4"

"nov 04"

But note if you use the single digit date format it'll kinda bunk up your free text search (ctrl-f), cuz the site formats single digit dates with a zero prefix.

I may make the default version of the site load the current day delta as the default to cut bandwidth a bit. But I think for new users the first Q posts are a lot of fun to start with...
