Created page with "--[[ For a given 3- or 4-digit year or decade, find the most specific portal which actually exists. Takes one parameter, which must be either a year (e.g. "1879", "1123") or a decade (e.g. "1940s", "790s"). If a portal is found, return its name without the namespace prefix (e.g. for "Portal:1980s" return "1980s"); otherwise return an empty string. If the parameter is missing, empty, or does not fit the required format, an empty string is returned"..."
