Insert inactive date with elisp function including date arithmetic

Question

For a capture template I want to insert inactive dates for the upcoming week (without a prompt). In this format (no time component):

[2020-02-10 Mo]

I've figured out that I could do something like this
[%(org-read-date nil nil "Tue")] which yields [2020-02-11]. So it misses the weekday.

I also know about this method
(org-insert-time-stamp (org-read-date nil t "+1d")) but that timestamp is not inactive.

Answer 1

I was close with my last try.
Reading the documentation does help :)

%(org-insert-time-stamp (org-read-date nil t "+1d") nil t)
does the trick. And you can do any date arithmetic in the string part that you would do at the interactive prompt.
