Generally, formats support trailing parts, which are disregarded.

1. When the former of these formats overlaps with the latter, the
former is preferred
2. " ", ".", "-" and "/" are all supported as separator
3. Any sequence of non-alphanumerical characters are supported as
separator
4. This format is only assumed if the year is bigger than the month
5. This format doesn't support trailing parts
