Why is there such a discrepancy? In the English-speaking part of North America, it would appear that it is much more common to go with the month, then the day whereas in Francophone North America and (a good part of) Europe, among other places, usage favors the reverse. If I’m not mistaken, official documents like treaties and the like specify the day and then the month (DONE, this____ day of____1999). In addition, if you asked someone today what day it is, odds are that he or she would answer: “the 26th”, and not “June 26th”. How did the habit of putting the month first come about?
As for standardization, isn’t it long overdue? Even in English-speaking North America, you can find both variations (i.e. 06-26 and 26-06), which doesn’t pose a real problem in this case. But what about 03-04, for instance: March 4th, April 3rd?
Finally, the “electronic mode” doesn’t seem to have caught on much, beyond the computer world. although it is interesting to note that, in this format, the month again comes first, so to speak. What are the odds that it will spread?
