Avoid matching 4 char years with regex meant for days given as ordinal numbers

Browse Source 
Original regex is probably meant to match dates like:
1st Jan 2012
but it also matches
127012025 21.01.2025
because the two chars following the first two can be any character including numbers.
This change excludes numbers there so dates following numbers are parsed correctly.
