Specifying Today in filter criteria

Specifying Today in filter criteria

In looking at custom views, I can't find a way to specify "today" (or now or whatever) as part of the filter criteria. My initial look suggests I can only hardcode a date.

I found a post here that asked for this 6 years ago but nothing indicating this was ever added.

It seems such an obvious option, I am hoping search has let me down and there is a way to specify @today (or something like that).

Indeed, I would expect to be able to include filters of the form "today + 14 days" and the like.

Can someone point me in the right direction?
