Mar 13, 2022Daylight saving time

Just like the European hare, we get a little more hop in our steps this time of year—and a bit more daylight as well. It"s the second Sunday of March, when most Americans and Canadians "spring forward," setting their clocks ahead one hour in observance of daylight saving time (DST). Then on the first Sunday of November, we"ll "fall back" by turning our clocks back an hour.Desktop Version

Mar 14, 2022Pi Day

Did Neolithic humans build this structure to celebrate Pi Day? Not likely. Pi Day is a relatively recent phenomenon—invented by a physicist in 1988 and designated by Congress a national holiday in 2009. But it"s already almost certainly the most popular holiday celebrating a mathematical constant. While Pi Day is a young tradition, the number π (pi) itself has been a fascination since antiquity, when it was first calculated as the ratio of a circle"s circumference to its diameter.Desktop Version

Mar 15, 2022Beware the Ides of March

We"re at the Roman Forum for the Ides of March, a date made famous as the time of Julius Caesar"s assassination. According to the ancient historian Plutarch, Caesar had been warned by a seer that his life would be in danger no later than the Ides of March, something that William Shakespeare dramatizes in his famous tragedy of Caesar’s life and assassination. While historical fact and fiction can diverge, we do know that before March 15, 44 BCE was over, a group of senators had intercepted Caesar here in the Forum as Caesar was on his way to the Senate House. They stabbed him 23 times, killing him. Afterward, Rome descended into civil war, ending the Roman Republic, and leading to the rise of the Roman Empire.Desktop Version

Mar 16, 2022Panda Day

There"s just something comforting about giant pandas. They"re stoic but look cuddly, and their unusual black and white markings make them distinctive. Pandas are one of the animals we recognize from an early age. But while we may take them for granted, they"ve been under threat from shrinking habitats and food supply as people harvest bamboo and build roads and train tracks through their forests. National Panda Day on March 16 spreads awareness about these beloved bears and encourages us to safeguard their future.Desktop Version

Mar 17, 2022St. Patrick s Day

Ireland has been called the land of "40 shades of green," but this green leprechaun"s-eye view comes from the feet of California"s coastal redwoods. Today we celebrate St. Patrick, the patron saint of Ireland, who famously never traveled to California. St. Patrick is often depicted holding a shamrock, which he purportedly used to explain Christianity in Ireland by saying the leaves illustrated the Father, Son, and Holy Spirit of the Holy Trinity. Never mind that Celtic druids had revered the sacred shamrock and its three leaves long before Patrick"s arrival. Coins depicting St. Patrick with a shamrock date back as far as 1675.Desktop Version

Mar 18, 2022Holi festival

The ancient Hindu festival of Holi will find revelers caked in these colorful powders by the day"s end. Also referred to as the Festival of Spring, the Festival of Love, and the Festival of Colors, Holi is celebrated during the full moon in the Hindu calendar month of Phalguna, which falls around the middle of March in the Gregorian calendar. This year it"s March 18. Holi symbolizes the triumph of good over evil and celebrates the beginning of spring, the end of winter, and the blossoming of love in all forms. It"s a time for affirming friendships, burying old grievances, and letting romance bloom.Desktop Version

Mar 19, 2022Chicagohenge

During the fall and spring equinox, the celestial phenomenon known as Chicagohenge occurs when the sun rises or sets directly between the buildings lining Chicago"s east- and west-facing streets. The city"s almost perfectly aligned grid is responsible for the event.Desktop Version

Mar 20, 2022World Frog Day

World Frog Day is celebrated every year on March 20, a chance to consider the world"s most famous tailless amphibian. The star of fairy tales, cartoons, films, and TV shows, the charismatic and clearly photogenic frog accounts for almost all amphibian species. Frogs have been around for more than 200 million years, and although they live in both warm and cold places, most reside in tropical rainforests.Desktop Version

Mar 21, 2022World Poetry Day

"How like a winter hath my absence been / From thee, the pleasure of the fleeting year! / What freezings have I felt, what dark days seen! / What old December"s bareness everywhere!"Desktop Version

Mar 22, 2022World Water Day

You can almost hear the crash and feel the spray of this cluster of pristine waterfalls in southern Idaho. Could there be a better place to celebrate World Water Day? Since 1993, the UN has dedicated March 22 to advocate for sustainable management of freshwater resources and bring attention to topics relevant to clean water, sanitation, and hygiene. Each year a different aspect of this critical resource has been emphasized, with themes like "Valuing Water," "Water and Climate Change," "Water and Jobs," and "Why Waste Water?" This year"s theme is "Groundwater—Making the Invisible Visible."Desktop Version

Mar 23, 2022World Meteorological Day

Did you check the weather forecast today? Does it look like rain? Will it turn colder? What"s the outlook for the weekend? These questions may seem commonplace, even mundane, but the answers can be of crucial importance. Given our reliance on weather prediction, let"s tip the rain hat to the world"s weather experts on World Meteorological Day, celebrated each March 23 by the United Nation"s World Meteorological Organization (WMO).Desktop Version

Mar 24, 2022Red squirrel

Shhh, it"s sleeping. But don"t confuse that with hibernating. A tree squirrel, like this red squirrel in Scotland, doesn"t hibernate during the winter. Hibernating is more of a ground squirrel trait. But the red squirrel is particular about where it sleeps, mostly building its nest, or drey, high above the ground in the cavity of an evergreen tree. Nests are often lined with soft materials such as leaves, moss, and grass. This little sleeper is using its bushy tail to keep warm, with the help of some lichen and pine needles.Desktop Version

Mar 25, 2022Tolkien Reading Day

For Tolkien Reading Day, we"re visiting the Lauterbrunnen Valley in the Swiss Alps, which is believed to have inspired the Elven sanctuary of Rivendell in J.R.R. Tolkien"s novels "The Lord of the Rings" and "The Hobbit." Like Tolkien"s mythical Elf settlement, Lauterbrunnen Valley has a bit of storybook appeal, with an unusually narrow valley floor hemmed in by steep Alpine cliffs and dotted with numerous waterfalls. Lauterbrunnen became popular among mountain climbers and hikers beginning in the late 19th century, and Tolkien hiked through the valley in 1911. The valley remains a popular tourist destination.Desktop Version

Mar 26, 2022Spring awakens

No flower better signals the start of spring than crocuses, early bloomers that come in Easter egg colors such as purple, lavender, orange, pink, and yellow. Crocuses are perennial, flowering bulbs that are built for toughness. As you can see, the plants are able to endure frost and even snow because their flowers and leaves are protected by a waxy cuticle. That"s why the first blooms you see in spring are often crocuses. They can grow in a variety of environments, even in the high elevations of the alpine tundra above the tree line.Desktop Version

Mar 27, 2022World Theatre Day

What better place to celebrate World Theatre Day than the ancient theater of Taormina, Sicily, an amphitheater built in the Hellenistic style of the Greeks in the third century BCE. The venue was later expanded by the Romans and is one of the signature sights in Taormina. And if you look in the upper-right corner of the photo, that"s Mount Etna giving a performance of its own, spewing a little ash and smoke.Desktop Version

Mar 28, 2022Kawachi Fuji Garden

Today we"re taking a trip to a Japanese purple paradise. This photo captures just one of over 22 different varieties of wisteria planted at the Kawachi Fuji Garden in Kitakyushu, Japan. Hundreds of wisteria plants were meticulously cultivated to form tunnels that bloom with shades of blue, white, purple, and pink. The walkable tunnels open into large domes of wisteria vines for visitors to sit under and bask in the fragrant flowers. An overlook gives visitors an impressive view of not only the flowers but also the surrounding valley and its bamboo groves.Desktop Version

Mar 29, 2022Northern coast of Colombia

Colombia is the only country in South America that has coastline on both the Caribbean Sea and the Pacific Ocean. Seen here is a stretch of beach near Parque Nacional Natural Tayrona and the small town of Buritaca, on the Caribbean coast along Colombia’s north shore. This region boasts some of the most beautiful beaches in the country. It"s also among Colombia"s most ecologically diverse areas, with jungle, desert, and one of the highest coastal mountain ranges in the world, the Sierra Nevada de Santa Marta.Desktop Version

Mar 30, 2022Belted Galloway cows

These cool cows are Belted Galloways, also known as "Oreo cows." (And if you like a glass of milk with your cookies…) The heritage breed originated in the southwest of Scotland, and it thrives on the region"s rough pastures and windswept slopes. Belted Galloways fight the elements with a double-layer coat: The long, coarse hair diverts rain, and beneath that, the cow has a soft undercoat to keep it warm and dry in the harsh Scottish winters.Desktop Version

Mar 31, 2022Happy Birthday, Eiffel Tower

Locally, it"s called "La dame de fer," which translates to English as "The Iron Lady." To the rest of the world, it"s the Eiffel Tower, a landmark nearly synonymous with all things Parisian. It"s one of the most recognizable structures in the world and the most visited monument with an entrance fee. The Eiffel Tower took 500 workers two years, two months, and five days to complete. Most of the structural work was finished by the end of March 1889 and to celebrate, the builders led a group of government officials and journalists to the top of the tower on March 31. It was, at the time, the highest man-made structure in the world. With the addition of a new radio antenna on March 15, 2022, the Eiffel Tower grew an additional 20 feet and is now 1,083 feet tall, just in time for its 133rd birthday.Desktop Version

Apr 1, 2022April Fools Day

In honor of April Fools" Day, take a moment to appreciate this trick of the eye created by the French street artist and photographer who goes by the name JR. He"s known for surreptitiously posting large black-and-white photographs in public locations, often in humorous contexts. This cheeky public-art piece from 2021 was installed in the desert sands of the Giza pyramid complex in Egypt. The installation makes it look as if the detached tip of the Pyramid of Khafre magically hovers above its base.Desktop Version

Apr 2, 2022Whangārei Falls in New Zealand

This lush, Eden-esque location on New Zealand"s North Island has been a popular spot to bring a blanket and picnic basket for generations of Kiwis. Whangārei Falls is part of the Hātea River. At the falls, the river drops 85 feet over a basalt lava flow. The surrounding park provides a loop trail ideal for a hike along the edge of the river.Desktop Version

Apr 3, 2022Lake Tai s cherry trees in bloom

The tranquil appearance of Lake Tai belies its location within Wuxi, China, a metropolis of 7.5 million people in southern Jiangsu province. A short distance to the east is the megacity of Shanghai. But city life feels a world away here at China"s third-largest freshwater lake. More than 20 miles across in places, Lake Tai provides a needed retreat from urban life, drawing locals and tourists to its picturesque shores.Desktop Version

Apr 4, 2022Norway s Kjeragbolten boulder

If you have nerves of steel, you"d enjoy the precarious, one-of-a-kind photo op that is the Kjeragbolten boulder. Visitors climb up Kjerag, a mountain on the southwest coast of Norway, for the chance to clamber onto the stranded rock and have their daredevil pic snapped for posterity. Indeed, Kjeragbolten is so popular that you might have to wait up to an hour for your turn—plenty of time for second thoughts and jitters.Desktop Version

Apr 5, 2022Goðafoss waterfall, Iceland

Goðafoss is one of the hundreds of show-stopping waterfalls Iceland is blessed with. And though it isn"t the island"s highest waterfall—that would be Morsarfoss at over 787 feet—or most powerful (the thundering Dettifoss), Goðafoss, has, within its swirling waters, its own story to tell.Desktop Version

Apr 6, 2022Crested caracaras

Crested caracaras are no strangers to spring fever. These members of the falcon family make their intentions loudly known, throwing their heads back with guttural calls and cackling cries to attract a partner. Couples are loyal to each other and to their home, mating for life and returning yearly to the same nesting site and even the same tree. This courting pair is in the grasslands of Texas, the northern extent of the crested caracara’s range. The striking birds can be found in pastures, farmland, deserts, and savannas from the southern United States all the way down to the southern tip of South America.Desktop Version
