Legend has it that Archimedes, born in the year 287 B.C., made his discovery while sitting in the bathtub and celebrated the revelation by running through the streets proclaiming, "Eureka, eureka!"
The mathematician's discovery was said to have occurred one week before the start of summer, the date known today as June 14.
The National Day Calendar said the holiday is meant to spark bath time creativity in children and adults alike.
Other holidays and observances for June 14, 2022, include Call Your Doctor Day, Family History Day, Flag Day, Magic Circles Day, National Bourbon Day, National Strawberry Shortcake Day, Own Your Share of America Day, Pause for the Pledge Day, Pop Goes the Weasel Day, Ryan Moran Day, World Blood Donor Day and World Pet Memorial Day.
