I do know it is easier to validate input data in real-time. Once you have the month you know how many days the day will be maximum with the exception of leap years when you need to know the year as well. If you enter day then month you could enter a valid day like 31 and then if you enter 11 for November you then have an invalid date. Either way it is somewhat perplexing and now we have better data entry with the month in words as a drop down in many walks of apps which negate this possible nightmare of 10/11/13 being 10th of Novemeber 2013 or 11th of October 2013. I'm sure many of you have nightmare stories over this date format without even going into the nighmare known as TimeZones.
