Specifically, I'd like to sort a column in a table in org-mode. However, the column only has year and month information, like 2016-02 or May 2016. It can't sort for now as it's not recognised as timestamp. How can I make it to work properly?
org-mode timestamp must have a day. However if you give the months in the form "2016-02" then time sorting and alphabetical sorting are the same (so long as you're careful to keep everything padded to the same length).
