Sure you can tell. You just hire an investigator to find out who wrote the memo, and find where in the world they grew up, in what culture.

If the answer comes back very US, then it's middle endian US format. Else it's DMY.

Note that the article is wrong to just say "dd.mm.yy" is used in "Europe". Some countries use yyyy-mm-dd and others dd/mm/yy.

The US format is the only one that's retarded, though.
