Times 28287 – two kinds of firsts.

My first time blogging for the new site then copied here, as opposed to last week’s when that process was reversed. As it happened, I found this puzzle an easy one and set a new PB by completing it in 10 minutes and a few seconds. Afterwards I looked up 17a on Wikipedia, it was a word I’d heard of in a calendar context but didn’t know what or when it was. Not much else to add about this one.
