On Cinco de Mayo, 2023, people also celebrate Square Root Day, which originated when Ron Gordon first linked the day’s date with its square root in 1981. The Gordons enjoy creatively marking mathematically-themed days. For Square Root Day, they celebrate with square-shaped food like steak with root vegetables, embodying a blend of mathematical appreciation and family tradition. This year's Square Root Day is special because 2023 is also a perfect square, making it a unique occasion worth celebrating nine times each century.
"When it was 11-11-11 with all the ones, we called it 'Ones Upon a Day.' Each of these, it's just a little math, a little smile, and a little fun."
"It’s a good day to get things squared away, to try to fit a square peg into a round hole, go square dancing, or root for the underdog."
