Celebrate These 10 Literary Holidays!!

I read an article on the Mental Floss website this morning titled 10 Literary Holidays by Hannah Keyser. I was aware of two of the ten literary holidays mentioned in Keyser's article... I now look forward to learning about and perhaps even celebrating the rest of the literary holidays mentioned. 

I was a bit surprised to see that World Book Night didn't make the list of literary holidays. Were you surprised by what was on the list of literary holidays and which holidays were not??
