How to date as tag

I want to use date tag as a reminder to see the whole topic one more time.

It can be by writing ##2022-08-03 - if the day exists in your knowledgebase it is referenced, if not, it can be added by !!.
If there is easier way, I’d like to know it as well.

You can also create a new daily document and insert a reference to it via !! , which will open a calendar picker - since everything is a rem, there’s no particular reason to use a tag over a reference unless you don’t want the reference’s text/want a transitive tag/will query for that tag. Of course, you can also always cloze any character of any rem via { to have it pop up in queue.
