A helper module to find the most specific chronology portal which actually exists for a given year or decade. Used to simplify linking to a chronology portal.
Takes one parameter, which must be either a year (e.g. "1879", "1123") or a decade (e.g. "1940s", "730s").
If the parameter is missing, empty, or does not fit the required format, an empty string is returned.
Output
If a portal is found, returns its name without the namespace prefix, e.g.
- for "Portal:1980s" return
1980s - for "Portal:19th century" return
19th century
If no portal is found, it returns an empty string.
