When the day or month is omitted from one of these patterns, the compiler assumes it has a value of 1.

If the day or month are not omitted but out of range, for example 00/38/11, a message is issued if the date involves a comparison. Exceptions to the rules are cases of patterns YYMM and YYMMDD with values of all zeros that will be converted to a Julian date of 1, that, is, the smallest valid date.
