Happy Pi Day!
Happy Pi Day!
They say the only constant in life is change. In mathematics, however, there are many constants, and today, we"re celebrating perhaps the most famous of them all: pi. This tasty-sounding constant is the ratio of a circle"s circumference to its diameter, approximately 3.14159. Every March 14, mathematics fans across the world get baking to mark Pi Day—a celebration of both the mathematical constant π and its delicious homophone, pie. It began in 1988, when physicist Larry Shaw connected the date (3/14) with the first three digits of this constant. Today, mathematicians and enthusiasts celebrate Pi Day with pie eating and pi reciting. Did you know that when your clock strikes 1:59 today, you will be three decimal places closer to the real value of pi? Pi is everywhere, even in nature. Pictured here is a bodhi tree in the shape of the pi symbol at Wat Phra Ngam, a temple in Ayutthaya, Thailand. Whether you"re a math geek or just in it for the treats, Pi Day is for everyone to enjoy!Desktop Version

Japan Castle Day
Japan Castle Day
From Strawberry Day to Cat Day and even Vegetable Day, Japan has a list of faux holidays, which are the clever results of "dajare" or word plays. Today"s date, April 6, makes up the Japanese word for castle, "shiro" from "shi" (4) and "ro" (6). Hence, the celebration of castles. What better opportunity than Castle Day, to learn about the country"s largest and most visited castle—Himeji Castle? Dating back to 1333, this UNESCO World Heritage Site boasts an advanced defensive design and five National Treasure structures. The castle has also withstood time and nature"s fury, surviving the bombings of World War II and the Great Hanshin earthquake in 1995. In addition, nearly 700 years of glory, local legends and ghost stories reverberate through the 83 rooms of this hilltop fortress. Would you care to explore?Desktop Version

The Great Wall of China
The Great Wall of China
Think the Great Wall of China is just a long wall? Think again. It is a combination of walls and steep trenches that have protected China for centuries. One of the longest manmade structures in the world, this wall stretches over 20,900 kilometres and dates back thousands of years. Back then, glutinous rice flour was used to bind the bricks of the wall. The ancient marvel depicted in today"s picture consists of a series of fortifications that span rugged mountains, valleys and deserts. Featuring watchtowers and garrison stations, some sections were designed to keep invaders at bay. This wall was designated a UNESCO World Heritage Site in 1987. Hiking offers a unique glimpse of this historical landmark. The experience ranges from well-preserved sections, like Mutianyu, to wild, unrestored parts such as Jiankou. Some steps are so high they feel more like climbing a ladder!Desktop Version

Berlin Cathedral and Museum Island, Berlin
Berlin Cathedral and Museum Island, Berlin
As the summer is fading away, we find ourselves reminiscing about vacations and long hours of lively evenings. But let"s not bury the picnic days just yet! There is plenty to look forward to, especially if you are in Berlin. The Long Night of Museums only happens once a year—on the last Saturday of August since 1997—but it shakes up Museum Island and the rest of the German capital. The event series is more than a peaceful appreciation of artefacts—quite the opposite—you can expect music, talks, workshops, cocktails, dance and more from 6 PM into the small hours of the morning. Featured in today"s image, Museum Island—embraced by the Spree River—is listed as a UNESCO World Heritage Site and it is home to a museum quintet: Altes, Bode, Pergamon, Neues Museums and Alte Nationalgalerie.Desktop Version

Canadian Tulip Festival
Canadian Tulip Festival
Ever spotted a field full of tulips and felt like you"d stepped into a painting? Well, you are not alone. Today, there are more than 3,000 registered varieties of tulips grown around the world. Originally found in the wild across Central Asia, tulips were cultivated by the Ottomans as early as the 10th century. These flowers made their way into Europe during the 16th century after being introduced through diplomatic and trade routes. By the 1630s, the Netherlands experienced tulip mania, one of the first recorded economic bubbles, where single bulbs could sell for more than a skilled worker"s annual salary.Desktop Version
Leap Day
Leap Day
Are you a "leapling?" No, not like this Eurasian red squirrel; rather, that"s the term for anyone born on leap day! A leap year is a calendar oddity that exists because Earth"s orbit and our usual year count are slightly out of sync. Earth takes 365 days, 5 hours, 48 minutes and 46 seconds, to revolve around the sun. To compensate for those extra 5 hours, February gets an extra day—leap day—every four years. The concept, dating back to the ancient Romans, was refined in the Gregorian calendar, introduced in 1582 by Pope Gregory XIII. While the purpose of the day is to keep our year aligned with the solar calendar, it can also serve as an extra day to prepare for spring! Cultures worldwide mark leap days and years with unique customs. In Ireland and Britain, women propose to men, in Greece, marrying during a leap year is said to bring misfortune, and in France, a satirical newspaper is published.Desktop Version
Przewalskis horses, Hustai National Park, Mongolia
Przewalskis horses, Hustai National Park, Mongolia
The Hustai National Park in Mongolia is home to a very special and rare breed of horse, the Przewalski"s horse. This equine species, which is regarded as the only truly pure wild horse today, is easily recognised by its pale yellowish-brown coat, a short, stiff mane, and short legs. The Przewalski"s horse, also called "takhi" in Mongolia, was once extinct in the wild but has been successfully reintroduced through conservation efforts in the 1990s. An interesting fact about these horses is that they have 66 chromosomes, compared to 64 in domestic horses. Remarkably, Przewalski"s horses can mate with domestic horses to produce hybrids. These hybrids have 65 chromosomes and can breed and have their own offspring.Desktop Version

Victoria Day
Victoria Day
Every May, Canadians roll out the red carpet and prep the fireworks for a queen who never set foot here. Victoria Day marks Queen Victoria"s birthday—24 May—and has been observed since 1845, celebrated on the Monday preceding that date. Officially recognised as a holiday in the mid-19th century, it"s a nod to the country"s colonial roots and a reminder of the queen"s lasting influence. It"s more than just a long weekend; for many, it marks the unofficial start of summer, with parades, picnics and festivities across the country, particularly in British Columbia.Desktop Version

Three Natural Bridges, Wulong National Park, China
Three Natural Bridges, Wulong National Park, China
Carved by nature over centuries, the Three Natural Bridges in Wulong Karst, China, is a geological wonder. These limestone bridges, towering over a deep gorge, are named after three dragons: Tianlong (Sky Dragon), Qinglong (Azure Dragon) and Heilong (Black Dragon). Tianlong, standing at 235 metres, has a bridge-pier with maze-like caves in it. The Qinglong Bridge, which is 281 metres high, offers breathtaking views when the sun is out. Heilong Bridge is the widest of the three bridges at 193 metres and reaches a height of 223 metres. Visitors can explore the Wulong Karst National Geology Park and visit places like the Furong Cave, a 2,846-metre cave with huge limestone stalactites, which are mineral formations that hang from the ceiling. Standing beneath these magnificent natural bridges, you can"t help but be humbled by the sheer power of time and nature.Desktop Version
