I've correctly solved each puzzle and have a combination for the pieces that satisfies every rule, but it didn't work. In past years' calendars, there seemed to be only one unique final solution, but this year there seem to be multiple options. Are we allowed to order more than one part from the same company?


Also, I think the clues on the 19th and 20th are breaking my brain. How do I know that I can trust anything that is said on December 20th?

@Katharine: I only had one combo that worked. Once you wrap your head around the 19th and 20th, things should sort themselves out.

For 19th and 20th, yeah they warped my brain for a while too. The way I thought about it was this: if the 19th is true, can the 20th be true or false or is it a broken? (Remembering how "and" statements work with true/false: both have to be true for the full statement to be true.) And if the 19th is false, can the 20th be true or false or is it broken?
