United Nations Day marks October 24, 1945, when the UN Charter entered into force — establishing the organization that now has 193 member states and coordinates global action on peace, human rights, development, and climate. Make a Difference Day is organized by Points of Light on the fourth Saturday of October as one of the largest national days of community service, with more than 1 million volunteers participating annually. National Food Day was established by the Center for Science in the Public Interest in 1975 and relaunched in 2011 to advocate for affordable, healthy food, fair food labor, and sustainable food systems — observed with educational events, cooking demonstrations, and food policy advocacy. National Bologna Day celebrates the cured pork sausage — originally from the Italian city of Bologna, where mortadella is the authentic version — whose American mass-produced form became a staple of school lunches.
