I hate the fucking US date system - outside of US-land
It's also wrong. There are several countries outside of the US (or North America, or even the Western hemisphere) that do MM DD YYYY. There's also a rather large number that do YYYY MM DD (Japan and others) or YYYY DD MM (which is just plain fucked up IMO).
And, of course, any programmer worth their salt will tell you YYYYMMDD is the only one that makes any damn sense. It's sortable.
Yes, to be clear you should always spell out the month, but that doesn't have the "punch" they were looking for.
Honestly, I've long ago learned to figure out what format sites were using for their dates (generally DD/MM/YYYY or MM/DD/YYYY) and compensate appropriately.
