February 24: Holidays, Historical Events, Famous Birthdays & Zodiac Sign
Pope Gregory XIII used February 24 to announce a new calendar that would eventually replace the Julian system used since Roman times — reshaping how the world measures time itself.
About February 24
February 24 carries an unusual concentration of beginnings. In 1582, Pope Gregory XIII issued the bull Inter gravissimas, introducing the calendar that most of humanity uses today. Nearly three centuries earlier, in 1304, the great Moroccan wanderer Ibn Battuta was born — a man whose journeys across the medieval world would cover more ground than any explorer of his era. And in 1607, Claudio Monteverdi's L'Orfeo had its première in Mantua, earning recognition as one of the earliest true operas.
The day also carries profound political weight. Estonia declared its independence from the Russian Empire on this date in 1918, an act Estonians regard as the founding of their modern state — the subsequent Soviet annexation is considered illegal under Estonian law. Mexico's Flag Day falls on February 24 as well, honoring the national banner adopted during the country's struggle for sovereignty. And in 1803, the U.S. Supreme Court decided Marbury v. Madison, establishing the principle of judicial review that remains a cornerstone of American constitutional law.
Modern milestones continue the pattern. Steve Jobs, born on this day in 1955, would go on to co-found Apple and transform personal computing. Space Shuttle Discovery launched on its final mission, STS-133, on February 24, 2011. And in 2008, Fidel Castro stepped down as President of Cuba after thirty-two years in power, closing one of the longest chapters of Cold War-era leadership.
