The observance fosters dialogue about secularism and freedom of thought.
National Chia Day
National Chia Day honors this nutrient-packed superfood revered by the Aztecs and Maya for its energy-boosting properties. Chia seeds are rich in omega-3 fatty acids, fiber, protein, and antioxidants. Mamma Chia founded the day in 2016 to promote the seed’s popularity in modern diets.
National Chip and Dip Day
National Chip and Dip Day honors the satisfying combination of chips and dip. From guacamole and salsa to hummus and sour cream, the pairing has earned a permanent spot at parties and kitchen tables alike. The practice of dipping food is nothing new. Early hummus-like recipes appear in cookbooks dating back to the 13th century.
🥨 Just a few days earlier, on March 14, we celebrate National Potato Chip Day, making today the perfect excuse to grab your favorite dip and snack away.
National Melba Toast Day
National Melba Toast Day honors the dry, crispy, thinly sliced toast named after Dame Nellie Melba, a celebrated Australian opera singer. French chef Auguste Escoffier created both Melba Toast and Peach Melba (that has its own national day on January 13) in her honor. The toast remains a popular companion to soups, salads, and spreads.
National Near Miss Day
National Near Miss Day marks the date in 1989 when asteroid 4581 Asclepius passed within 500,000 miles of Earth. Scientists did not discover the asteroid until nine days after its closest approach. Had it struck, the impact would have released energy equivalent to a 600-megaton atomic bomb. The day underscores the importance of asteroid detection and planetary defense.
National Puppy Day
National Puppy Day celebrates puppies and advocates for adoption and responsible pet ownership. Founded in 2006 by pet lifestyle expert and animal behaviorist Colleen Paige, the day encourages people to consider adopting from shelters rather than buying from breeders or pet stores. Paige also founded National Dog Day and National Cat Day.
National Tamale Day
National Tamale Day pays tribute to a dish with roots stretching back thousands of years in Mesoamerica. Made from masa and filled with meats, vegetables, or cheeses, tamales are wrapped in corn husks or banana leaves and steamed. Richard Lambert, owner of Tamales-To-Go, founded the day in 2015.
OK Day
OK Day marks the anniversary of the word’s first appearance in print. On March 23, 1839, the Boston Morning Post used o.k. as a humorous abbreviation for oll korrect (all correct). What started as a newsroom joke became the most widely recognized word on the planet. Linguist Allan Metcalf created OK Day in 2011 to honor its unlikely journey.
🤩 Not to be confused with R U OK? Day* (Second Thursday in September), which focuses on mental health awareness.
