what format would you like us to use? dd month year, without any punctuation at all? (example: today is 17 August 2007)

the short date format, using two digits for month, day and year, is only ambiguous during the first 12 days of the month, when the order is not intuitively obvious (assuming a valid date). given that the average month is 365/12 or 30.42 days long, then ambiguity can only occur 39.5% of the time. Which is much greater precision than one gets in the form of specifications from an end user.
