Since we don't differentiate between years, months, and days, we don't know. It depends on how one's culture orders the digits in a date. It could be 2003 January 2. The military and Europeans give the day first. If so it could be 2003 February 1.
Many computers use year, month, and day order.
If so the notation represents 2001 February 3. This would cause considerable confusion, since these dates can differ from each other by years. We have lived with part of this problem for centuries. The day and month can be confused with each other. We have had this regardless of the year, but we have ignored it because we always represent our dates as month followed by day, as in April 7, except the military which wants it the other way, as in 4 July.
