Yes. See C-h i g (emacs)Regexps
However you need to put a backslash before the curly braces:
\{4]\} instead of {4}

"[0-9]\\{4\\}-[0-9]\\{2\\}-[0-9]\\{2\\}"
should do the trick. Note I used double backslashes (\\) within the
string. If your regex isn't in a string literal use single backslash
(\) .

hm... "[0-9]\\{4\\}" is fewer chars but "[0-9][0-9][0-9][0-9]" is
easier to read ...
