Inspired by 2024's Reading Glasses Challenge, here's a whole list of holiday-based prompts, separated by month. So, in the spirit of the original challenge item, read a holiday book on that holiday! Or, if you can't find any books that fit, fill prompts based on that holiday instead.
This list is based on observed US holidays and also based on Mallory's criteria of "there should be a celebration of that holiday" but please feel free to let me know about a holiday that should be added or even one that I should take off because it isn't actually celebrated in your culture.
