additional data point: the first article we see Yuuri reading before Celestino says not to read the news, at the top is 12月13日 後6時32分, which, I can read approximately no Japanese but that looked date-format enough that I poked Google Translate and sure enough that article is timestamped December 13 at 6:32 PM
which means either the December 10–13 on the wall includes officially scheduled competitions and practices only, with the banquet and (one hopes) the exhibition gala on the 14th, or the banquet was later that same night (what exhibition gala? or that was still the 14th even if the banquet was the 13th), or (imo likeliest, but this is still a data point so I may as well mention it as soon as I notice it) the people animating these frames should have put 12月12日
(kudos to the people animating these frames, though, this is also the first I noticed that Yuuri's phone browser has a loading-progress bar)
