Regex Editor & Tester

This regular expression identifies Norwegian dates written with a digit immediately followed by a non-period character and a Norwegian month name (like "1 januar" instead of "1. januar"). It checks for any digit followed by any character except a dot, and then matches one of the twelve months in Norwegian, ensuring the month ends with a space, newline, or end of string. It is primarily used to find formatting errors in dates where the required period after the day number is missing.
