There’s no easy way. You can create a whole bunch of format strings for every exact format you expect, and then try to parse the input using each one in turn (tip: the order you test the formats in is important); or you can write a custom parser (hopefully using a parser generator like ANTLR.) Or you could search around to see if there are any open-source libraries that do this … I just checked the About box of Fantastical (which has a really good date parser) but didn’t see anything relevant. Good luck!
