I meant to ask whether you have single digit month and day as birth month and date. For example 4th February would be 02/04 in mm/dd format and 13th February would be 02/13. In the 2nd scenario, it is very easy to figure out which two of the four digits are for the month and which two are for the day. First example of 02/04 can be confusing, since the first or the last two can be both be a month and day.
Since you used month/day/year format, I just wanted to double check with you and find out if you have single digit month and day (like 2nd Feb, 1 May etc) as birth month and date.
