National Eat What You Want Day was created to give people a guilt-free break from dieting, calorie counting, and food restriction — one day where the only nutrition rule is that there are none. National Technology Day is observed in India to mark May 11, 1998, when India successfully conducted its first nuclear weapons tests under Operation Shakti at Pokhran — a date that signaled India’s emergence as a nuclear power. Twilight Zone Day celebrates Rod Serling’s genre-defining anthology series, which premiered October 2, 1959, and redefined science fiction television by using fantasy to examine Cold War fears, prejudice, and the human condition. Hostess CupCake Day celebrates the chocolate snack cake introduced by Hostess in 1919, one of the longest-running commercially baked goods in American history. Guilt-free eating, a mushroom cloud, a fifth dimension, and a chocolate swirl.
