Least to most imo. Month has the lowest number, then days, then years.
I disagree with that ordering, but okay.
Day-Month-Year is also organized by the importance of the information. When you look at the date, you're probably looking for the day. Most people know what month it is and everyone except time travelers and people who have just woken up from a coma know what year it is. The day is the most important piece of information, and therefore goes first.
