I'm having trouble finding how to correlate XKCD numbers with dates, but I think this might be over a decade old.
ETA: In fact I'm sure it is, because Time (1190) is a decade old this year. Relevant XKCDs: https://xkcd.com/1624/, https://xkcd.com/891/, https://xkcd.com/1686/, etc.
Even better is just looking at the HTML and searching for the name or the number of the comic instead of playing games with mouseovers and popup text.
