Uwe, I suggest you to create a feature request at https://debbugs.gnu.org for emacs to add a function similar to strptime that can parse date-time string accordingly to given format, see info "(libc) Low-Level Time String Parsing" https://www.gnu.org/software/libc/manual/html_node/Low_002dLevel-Time-String-Parsing.html Actually, I suppose, you need a function that parses date accordingly to current locale. It can be added to the feature request as well (and Eli will say that since Emacs is a multilingual editor, there is no well defined "current locale").

Not sure what this is trying to do. If it's going from <2021-12-31> to
31.12.2021, you shouldn't escape the < or >, you are not matching the -, and
there are only 2 number matches. Maybe you want
<\\([0-9]+\\)-\\([0-9]+\\)-\\([0-9]+\\)>
to
\\3.\\2.\\1
?

Thanks the \{4\} surprise me. I tried
(query-replace-regexp "\\(\\<[0-9]*\\)\\([\\.]\\)\\([0-9]*\\>\\)" "\\3\\2\\1")
And that did not work.

This is Emacs, of course, so you could use query-replace-regexp (M-%)
with, for instance
\([0-9][0-9]\)\.\([0-9][0-9]\)\.\([0-9]\{4\}\)
as the pattern to search for and
<\3-\2-\1>
as the replacement. The converse is left as an exercise for the
reader. ;-)

Hi Does anybody know about a function that would convert between date format like 31.12.2021 to <2020-12-31> and back? Thanks Uwe Brauer
