Template:CenturyNav

next up is how to get the thing to work for centuries with 1 digit and 3 digits. Probably will use some kind of #switch. Something like #switch:{{#pos:{{PAGENAME}}|c. Then if the position of c is 5 it's a 1 digit century. if it's 7 it's a 3 digit century. and therefore the sub will have to take either the first, or the first 3 digits.
