Thanks Tony1 for your comment on my talk page about overlinking on the article (https://en.wikipedia.org/w/index.php?title=Cascavel&diff;=next&oldid;=586154280).  I see what you're saying about overlinking to dates.  I had been translating the document from the Brazilian Portuguese version to English and simply copied the original article's linking pattern.  It seems they may have different standards on the Portuguese version.  So in the future when I translate over a document from PT>EN, I'll strip out those extraneous links.  Cheers!
