How can an article have comments from a year before posting?

Chops et al-Thank you. .

Hi! This article is re-rerun. We re-run articles we think have timely importance/usefulness. Like one of the commenters below pointed out, the bottom of the article says, "This aritcle originally appeared on September 17, 2015. We're re-running because Thanksgiving is coming (and lots of pie and baked goods)!" Every article we re-run has this disclaimer, as to avoid confusion!

At the end of the rticle, in italics, it states, "This aritcle originally appeared on September 17, 2015. We're re-running because Thanksgiving is coming (and lots of pie and baked goods)! "

Maybe it was also posted a year ago and then refreshed and reposted.

I've noticed the editors reprint articles of perennial (sp?) interest, sometimes with full info on previous appearance, sometimes without.
