Countries around the world have different ways of writing a date like June 28, 2013 which is the American style. However, I think Japan has the best way of rendering the date, with the year, month, and day (2013年6月28日).
I find this especially true when I organize my digital photos. The file names of my photos follow the Japanese style. For example, 20130628-0001.jpg.
I also have my image folders named in the same fashion along with a title or key word(s) such as 20130628-UenoPark. It’s a lot easier to organize and find digital photos according to date. I don’t ever use iPhoto, etc., to organize photos.
