When I moved to the States it took me a while to get used to everything being non-metric, as well as dates being reversed. Today – in America – it’s Pi day, since it’s March 14, or 3/14. On May the 4th is Star Wars day. Meanwhile, the rest of the world probably looks upon these date celebrations with bemused eyes, as they write dates with day and then the month. For them, today is 14/3, which is nowhere near pi.
