Thanks, did you test it?
I am asking because for me 

#+LANGUAGE: 
#+EXPORT_FILE_NAME: /home/oub/Desktop/testdate.html
#+OPTIONS: toc:nil  
#+HTML_HEAD_EXTRA: <style> body {font-size:150%}</style>
#+MACRO: IDATE @@html:<span style="color: red">$1</span>@@

* Title {{{<2023-02-11>}}}
{{{(<2023-02-11>)}}}


Does not work when exporting to html, and I have recent developer org
version installed
