International Holocaust Remembrance Day was established by the UN in 2005 to mark January 27, 1945, when Soviet forces liberated Auschwitz-Birkenau — commemorating the six million Jewish people and millions of others murdered by the Nazi regime. National Chocolate Cake Day celebrates chocolate cake in all its forms — from dense German chocolate to Hungarian Dobos torte to the molten lava cake Jean-Georges Vongerichten popularized in 1987. National Geographic Day marks January 27, 1888, when the National Geographic Society was founded in Washington, D.C. — launching a magazine in October 1888 that has documented the world’s geography, peoples, and species ever since. Library Shelfie Day shifts to the last Wednesday of January in 2027, celebrating the library shelfie — the photograph of a personal or institutional book collection that library social media has elevated into an art form.
