according Wayback Machine, the site still says NO even on Christmas. --valepert (talk) 21:56, 2 December 2019 (UTC)

Hmmm, maybe it will be fixed this year. I imagine everybody spammed the guy on twitter when it didnt work last year. 22:06, 2 December 2019 (UTC)
It checks your system time
It uses the new Date() constructor to check whether it is Christmas, which uses your system time. Thus, the Wayback won't get anything, but changing your system time will. Kay? That's right, Jacky720 just signed this (talk | contribs) 22:14, 2 December 2019 (UTC)

Okay so looking at, there's a comment at the top of the page saying to look at the console, but I don't see anything in there, anyone know what that might be about? Also at the bottom of the html file, the bottommost <script> tag looks like it might contain code for a chat client? I don't know JS so I'm unsure, but I tried changing all the related "false" values to "true" that looked relevant and nothing happened, so idk. Maybe someone else can figure it out. 22:03, 2 December 2019 (UTC)

Well, one way to put it is that the overall probability of a false negative is 0.27%, which doesn't seem too bad, but the conditional probability of a false negative given that it's Christmas is 100%, which is horrid. --IByte (talk) 22:37, 2 December 2019 (UTC)
