 * decadedigit is the single digit decade, e.g. 5 for the years 50-59 in the above century year.
 * centuryname is the equivalent name of that century, such as 19th for the period 1801-1900 (or 1800-1899 depending on your opinion as to whether year '0' is part of that century), 20th for 1900-1999 or 1901-2000, 21st for 2000-2099 or 2001-2100 etc.

So if one were to code   it would generate a text of Architecture completed in the 1430s plus a reference box referring to  category:15th century architecture and would generate links for 1400s architecture, 1410s etc. through 1490s architecture along with a category for 1430s architecture.
