Over 2,000 years ago, Julius Caesar promoted the use of the Julian calendar, a 365-day calendar that didn't account for leap years. Eventually, the calendar fell out of sync with the seasonal equinoxes, and holidays—like Easter—didn't land where they should. Finally, in 1582, Pope Gregory XIII mandated that Catholic nations switch to a new Gregorian calendar that solved the problem. But for many countries, including Russia, the switch from the Julian calendar to the Gregorian took centuries. As a result, in 1908, the Russians missed the first 12 days of the Olympics, which were hosted in London, because they were still using the Julian calendar. The country finally changed over in 1918 after the Bolsheviks took control. Fun bonus fact: Greece, the country where the Olympics were born, was the last nation to make the switch in 1923.
