May strolls in like it’s got nowhere to be and all the time in the world. Flowers bloom, birds sing, and suddenly everyone remembers they own flip-flops. It’s the month where spring hits its stride and lawn mowers wake from hibernation with a roar. Holidays in May are all about moms, margaritas, and memorials—and sometimes all three at once if you're doing the weekend right. It’s the gentle nudge before summer’s full cannonball, and honestly, May deserves a round of applause just for making us forget how weird March was.
Singing out is one of those glorious acts of human expression that walks the fine line between brilliance and public disturbance. One minute you’re passionately belting out your favorite tune like you're headlining Madison Square Garden, and the next, your cat is hiding under the couch and your neighbor is googling noise-canceling headphones. But that’s the beauty of it—singing out isn’t about being good, it’s about being loud, proud, and just delusional enough to believe the world needs your rendition of “Total Eclipse of the Heart” at full volume on a Tuesday morning.

Celebrating Harry Potter is the only time it’s socially acceptable for grown adults to wave sticks around, shout Latin gibberish, and demand a letter from an owl. You start the day fully intending to keep things low-key—maybe just rewatch The Sorcerer’s Stone. But before you know it, you’re dressed in house robes, debating whether you could survive on pumpkin pasties alone, and dramatically whispering “Always” at anyone who will listen. And let’s not forget the Sorting Hat crisis—because no matter how many times you take the quiz, you still question if you’re truly a Ravenclaw or if the algorithm is just messing with you.

Without proper weights and measures, buying a pound of apples could mean anything from a generous bagful to a single, slightly judgmental Granny Smith—and don’t even get started on paying for gas by the "almost gallon." Accurate measurement isn't just about fairness; it's the thin line between a good deal and being swindled with a smile. And in the science lab? Well, let's just say that confusing grams with kilograms or inches with centimeters could turn a simple experiment into a fireworks display, a minor explosion, or, at the very least, a very stern conversation with the fire marshal. Precision matters—and not just because no one wants to accidentally invent a new crater in the parking lot.

Using sunscreen is the adult version of having your mom spit-wipe your face—mildly annoying but weirdly necessary. Sure, it might feel like you’re smearing mayo all over your body and end up looking shinier than a rotisserie chicken, but that’s the price of protecting yourself from turning into human beef jerky. Plus, skipping sunscreen in hopes of getting a tan faster is like skipping your seatbelt because you’re “only driving a few blocks”—technically possible, but also wildly unwise. So lather up, embrace the glow, and remember: lobster-red is not a summer fashion statement.

Cinco de Mayo: the one day of the year when Americans celebrate a Mexican military victory by wearing sombreros from party stores and washing down buckets of chips with questionable amounts of margaritas. Contrary to popular belief, it's not Mexican Independence Day—that’s in September—but don’t let that stop Chad from showing up in a poncho and shouting "¡Arriba!" at guacamole.

On September 14, 1814, lawyer Francis Scott Key was inspired to write the poem that eventually became the lyrics of the United States national anthem, “The Star-Spangled Banner.” During the War of 1812, British forces had captured Washington, D.C., and burned several major public buildings before turning their attention toward Baltimore. Key became involved after his friend, physician William Beanes, was taken prisoner by the British. He helped negotiate Beanes' release, but because the Americans had learned details of the planned attack, they were required to remain with the British fleet until the assault on Baltimore was completed.
From aboard a vessel in the Patapsco River, Key watched as British ships bombarded Fort McHenry through the night of September 13 and into the morning of September 14. When daylight came, the enormous American flag flying above the fort was still visible, showing that the defenders had held their position and the British attack had failed. Moved by the sight, Key began writing verses that became a four-stanza poem titled “Defence of Fort M'Henry.” It was soon published and sung to the melody of “To Anacreon in Heaven,” a British song composed by John Stafford Smith. Over time, Key's poem became better known by the title of its opening imagery, “The Star-Spangled Banner.”
Key, born August 1, 1779, in Maryland, was a prominent lawyer who later served as U.S. attorney for the District of Columbia. His song became increasingly associated with patriotic and official occasions, and President Woodrow Wilson directed that it be played at appropriate military and naval ceremonies in 1916. Congress formally designated “The Star-Spangled Banner” as the national anthem, with President Herbert Hoover signing the measure into law on March 3, 1931. Key did not live to see what became of his composition; he died on January 11, 1843, decades before his hastily written verses became the official musical symbol of the United States.
On September 14, 1964, Kellogg's introduced the toaster pastry that would become Pop-Tarts, although the company was not the first to announce the idea. Rival Post had already publicized plans for a shelf-stable, fruit-filled pastry called Country Squares but revealed the concept before the product was ready for widespread sale. Kellogg's recognized the opportunity and moved quickly, turning to William “Bill” Post, then working at the Hekman Biscuit Company in Michigan, to help develop a pastry that could survive both the supermarket shelf and a trip through the family toaster. Post and his team experimented with dough, fillings and production methods, with his children reportedly serving as enthusiastic taste testers along the way.
Kellogg's initially considered calling its creation Fruit Scones before settling on the far more memorable Pop-Tarts, a name that played nicely with the popularity of Pop Art during the 1960s. The original unfrosted pastries appeared in four flavors—strawberry, blueberry, brown sugar cinnamon and apple currant—and the early test market was enormously successful. Demand quickly outran supply, forcing Kellogg's to publish advertisements apologizing to customers because it had run out. Frosting arrived a few years later after the company developed a version capable of surviving toaster temperatures without melting into a sugary disaster, followed by sprinkles, additional flavors and Milton the Toaster, an animated mascot who helped promote the increasingly popular breakfast treat.
What began as a hurried response to a competitor became one of Kellogg's most recognizable products. William Post is frequently described as the inventor of Pop-Tarts, although he always emphasized that their creation was a team effort, and Kellogg's has also credited company executive William “Doc” Thompson and the people involved in developing the product. Over the following decades, Pop-Tarts expanded far beyond those original four flavors and became as much a snack as a breakfast food. Billions are now sold annually—a remarkable outcome for something that began with a few people looking at two pieces of dough with filling between them and essentially asking, “Do you reckon we can put this in a toaster?”
On September 14, 1974, Eric Clapton reached No. 1 on the Billboard Hot 100 with “I Shot the Sheriff,” a song written and recorded the previous year by Bob Marley and the Wailers for their album Burnin'. It became the only No. 1 single of Clapton's career in the United States, but the man singing it had been surprisingly uncomfortable about releasing it. Clapton admired Marley's original and understood reggae well enough to worry that his own recording didn't capture what made the music special. He later recalled thinking that his version shouldn't even be included on his album 461 Ocean Boulevard, much less released as a single, because he felt it wasn't fair to Marley and that his interpretation had given the song too much of a white rock feel. His American bandmates were considerably more enthusiastic, and eventually Clapton allowed himself to be persuaded.
His concern became even more understandable when the record took off. Marley's version had already been released, but Clapton's recording suddenly carried the song onto mainstream American radio and all the way to the top of the chart. Clapton subsequently spoke with Marley and was relieved to discover that the songwriter appeared pleased with what he had done. Marley later recalled that Clapton had asked him about the meaning of the song, while Clapton remembered struggling to understand parts of Marley's explanation. Whatever uncertainty remained about the interpretation, there seemed to be no lasting uncertainty about Marley's acceptance of the cover.
The irony was that the recording Clapton worried might unfairly overshadow Bob Marley ultimately helped bring enormous attention to him. Island Records founder Chris Blackwell later described Clapton's cover as a major breakthrough for Marley, because one of rock's biggest stars had effectively pointed his enormous audience toward the Jamaican songwriter whose work he admired. The official Bob Marley history similarly credits Clapton's recording with significantly increasing Marley's international profile. So while September 14, 1974, marks Eric Clapton reaching No. 1, the longer story belongs to both musicians: Clapton received the biggest American single of his career from a Bob Marley song, while millions of listeners who heard Clapton's version were given a reason to discover the man who had written it in the first place.
On September 14, 1982, Princess Grace of Monaco died at the age of 52, one day after suffering serious injuries when the car she was driving left a steep mountain road above Monaco. Her youngest daughter, Princess Stéphanie, was traveling with her and survived. Before becoming European royalty, Princess Grace had been Grace Kelly of Philadelphia, one of Hollywood's most celebrated stars of the 1950s. In a remarkably brief film career, she became known for an elegant screen presence that made her particularly memorable in Alfred Hitchcock's Dial M for Murder, Rear Window and To Catch a Thief. She also starred opposite Gary Cooper in High Noon and won the Academy Award for Best Actress for her performance alongside Bing Crosby in The Country Girl.
Born in Philadelphia on November 12, 1929, Kelly studied acting at the American Academy of Dramatic Arts in New York and supported herself through modeling and television work while pursuing stage roles. After appearing on Broadway and making her way into motion pictures, her rise was extraordinarily rapid. By the middle of the 1950s she was one of Hollywood's leading actresses, working with stars including James Stewart, Cary Grant, Clark Gable, Ava Gardner and Frank Sinatra. Yet at the height of that success, Kelly walked away from Hollywood. After meeting Prince Rainier III of Monaco in 1955, she married him in an elaborate ceremony the following April and became Princess Grace. Her final feature film, the musical High Society, was released in 1956, bringing an acting career of only a few years to a close.
Princess Grace and Prince Rainier had three children—Caroline, Albert and Stéphanie—and she spent the remainder of her life carrying out royal and charitable duties in Monaco. On September 13, 1982, while driving home with Stéphanie, Grace lost control of her Rover on the winding road near Monaco and the vehicle plunged down a steep slope. Early reports attributed the crash to a stroke suffered while she was driving, although the precise circumstances surrounding the accident have remained the subject of discussion. Stéphanie escaped with injuries, but Grace suffered devastating trauma and died the following day. Her death prompted mourning far beyond the tiny principality she had made her home, closing an extraordinary life that had taken her from Philadelphia to Broadway, from Hollywood stardom and an Academy Award to becoming one of the world's most recognizable princesses.
On September 14, 1994, Major League Baseball officially canceled the remainder of its season, including the postseason and World Series, after a players' strike that had begun on August 12 showed no sign of ending. It was an extraordinary moment for America's pastime: for the first time since 1904, there would be no World Series, and for the first time since the championship series began in 1903, its cancellation resulted from a labor dispute. At the center of the conflict were long-running disagreements between team owners and the Major League Baseball Players Association over salaries, revenue sharing, free agency and the owners' desire for a salary cap. Acting commissioner Bud Selig finally called off the remainder of the season with hundreds of regular-season games already lost.
The cancellation was particularly painful because the 1994 season had been producing some remarkable baseball. The Montreal Expos owned the best record in the majors at 74–40 and appeared capable of making the deepest postseason run in franchise history, while the New York Yankees led the American League East at 70–43. Individual achievements disappeared with the schedule as well. San Francisco's Matt Williams had already hit 43 home runs and Seattle's Ken Griffey Jr. had 40, giving both a chance to challenge Roger Maris' then-record of 61 in a season. Perhaps the most tantalizing unfinished story belonged to San Diego Padres great Tony Gwynn, who was batting .394 when play stopped and pursuing something no major leaguer had accomplished since Ted Williams hit .406 in 1941.
The dispute continued through the winter and into the following spring, with replacement players even appearing during 1995 spring training before a federal court injunction helped bring the strike to an end on April 2. Regular major-league players returned and the 1995 season eventually began, but the damage was considerable. Attendance suffered, fans expressed anger at both players and owners, and many people within baseball later described the canceled World Series as a lasting scar on the sport. There was no champion, no postseason heroics and no opportunity to discover whether Montreal could complete its remarkable season, whether Gwynn could reach .400, or whether Williams or Griffey could catch Maris. The 1994 season simply stopped—and baseball was left forever wondering how one of its most promising years might have ended.
