When you type it out and hit enter, should it convert the tag to a proper date? Otherwise the problem is that the >today part is dynamic and the date would always keep moving forward one day.
Eduard Metzger: I’d want it to convert to a proper date. Just a way to quickly calculate the desired due date
Eduard Metzger: maybe >now would be today/ongoing? And >today would be the date?
Scott Bates: Building on your idea, how about having it >now would make it everlasting every day until completion. That's a neat way to have something floating around if you need to :-) But other than that, I agree that if you type it out like >today+21d should just replace that with the actual date.
Fantastical Style for the win! (such good natural language parsing)
I'd like to tag on a request to be able to use natural language, ie: >nextmonday
one possibility is to use a typinator shortcut to type > followed by the "date 3 weeks from now" for this, eg. shortcut dw3 expanding to >20xx-xx-xx with >{{dayDelta=+21}}{YYYY}-{MM}-{DD}. It doesn't reschedule the task to that day but the task appears in the references and can be dragged into the daily note. Once dragged, it disappears from the old daily note.
