Yule - Day of Winter Solstice


Yule is observed on the day of the Winter Solstice.

Also known as Jul, Yule predates the Christmas holiday by thousands of years. There is some debate as to the origin of the word Yule. Some linguists suggest the word is derived from “Iul”, the Anglo-Saxon word for wheel. This makes a connection to a Celtic calendar, the Wheel of the Year. In the Norse culture, “Jul” refers to the god, Odin. Odin was celebrated during Yule as well.

Yule celebrations included bonfires, decorating with holly, mistletoe and the boughs of evergreen trees, ritual sacrifices, feasts and gift giving.

Do you recognize any Christmas traditions borrowed from Yule?

  • The Yule midwinter feast usually lasted 12 days.
  • Vikings would decorate evergreen trees with gifts such as food, carvings, and food for the tree spirits to encourage them to return in the spring.
  • Mistletoe combined with a mother’s tears resurrected her son, the God of Light and Goodness, in a Viking myth. The Celts believe Mistletoe possessed healing powers as well and would ward off evil spirits.
  • In Norse tradition, Old Man Winter visited homes to join the festivities. The Viking god, Odin was described as a wanderer with a long white beard and is considered the first Father Christmas.
  • Viking children would leave their shoes out by the hearth on the eve of the winter solstice with sugar and hay for Odin’s eight-legged horse, Sleipnir.
  • Children would traipse from house to house with gifts of apples and oranges spiked with cloves and resting in baskets lined with evergreen boughs.
  • The Yule log was a whole tree meant to be burned for 12 days in the hearth. The Celts believed the sun stood still during the winter solstice. They thought by keeping the Yule log burning for these 12 days encouraged the sun to move, making the days longer. The largest end would be fed into the hearth, wine poured over it, and it would be lit with the remains of the previous year’s Yule log. Everyone would take turns feeding the length of timber into the fire as it burned. Letting it burn out would bring bad luck.

While the winter solstice is observed around the world, Yule was celebrated primarily by Germanic cultures of northern and western Europe. The midpoint of winter was a time to celebrate the rebirth of the sun and the light it would bring to the earth.

WINTER SOLSTICE – Day Between December 20 and 23


The winter solstice is the shortest day and longest night of the year in the Northern Hemisphere. It occurs annually between December 20 and December 23.

The winter solstice is marked by the point at which the North Pole is at its farthest from the sun during its yearly orbit around the sun. It will be approximately 23 degrees away from the sun.  Despite the temperature outside, the winter solstice is considered the astronomical beginning of winter.  Meteorological winter begins December 1 and lasts until the end of February and is marked by the coldest average temperatures during the year.

Depending on how far north a person is in the Northern Hemisphere during the winter solstice, their day can range from 9.5 hours to absolutely no sunrise at all.  On the bright side, the days will gradually become longer in the Northern Hemisphere until the summer solstice in June.  In the Southern Hemisphere, this same day marks the summer solstice and the Southern Hemisphere’s longest day of the year.

The vernal equinox and the autumnal equinox conventionally mark the beginning of spring and fall respectively and occur when night and day are approximately equal in length.

Around the world since ancient times to modern day, celebrations, festivals, rituals and holidays recognizing the winter solstice have varied from culture to culture.

Since the marking of time and the earliest calendars, this day marked the hardest time of the year for early people.  Survival was paramount when food and heat are not reliable.  In all corners of the Earth, there are ancient remains that seem to have been built around marking the winter solstice.

  • Probably the most famous of these is Stonehenge, England. Every year when the sun sets on the winter solstice, the sun’s rays align with two of the giant stones known as the central Altar and the Slaughter stone.
  • As the sun rises the day of the winter solstice, its rays illuminate the main chambers of the monument dating back to 3200 B.C. at Newgrange, Ireland.
  • In Tulum, Mexico an ancient Mayan city stands deserted. At the top of one of these buildings, a small hole casts a starburst when the sun rises on the winter and summer solstices.

Crossword Puzzle Day - December 21


December 21 commemorates the birth of a challenging word game enjoyed by millions around the world.  It’s Crossword Puzzle Day!

The first crossword puzzles were published in England in children’s books and other publications. They were simple word games derived from the word squares where letters were arranged in a square so that the words read the same across and down.

The object of a crossword puzzle is to fill in the white spaces of a grid with the correct words from the hints provided alongside the grid. The black spaces separate individual words. The clues to more challenging puzzles are more like riddles, making the game more complex.

Many tout the benefits of crossword puzzles. Not only are they fun, but challenging crossword puzzles may help delay the effects of dementia or sharpen the brain for problem-solving. They can also increase vocabulary and even relieve the mind from the stress of the day by focusing on something other than worldly problems.


Buy a crossword book or find one online. Enjoy some popcorn while you puzzle your way through your favorite crossword! Use #CrosswordPuzzleDay to post on social media.

Educators, check out Week 15 of the National Day Calendar Classroom for a lesson designed for you. 


Journalist Arthur Wynne from Liverpool is credited as the inventor of word game we know today.  He created what is considered the first known published crossword puzzle.  The puzzle appeared in the December 21, 1913, edition of the New York World newspaper.

National Underdog Day


Underdog Day is observed annually on the third Friday in December.

America loves underdogs.  In sports, people tend to rally around the person or team that is not favored to win.

An underdog is a person or team in competition most likely expected to lose.  This expectation can be based on statistical data, opinion or overall standings. When the underdog wins, it’s called an upset.  

The first recorded uses of the term occurred in the second half of the nineteenth century; its initial meaning was “the beaten dog in a fight.”

Also known as a Cinderella story, the underdog has long piqued Americans’ interest.  Whether in a sporting event, business, education or arts, when success is a long shot and a struggle as well, Americans root and cheer for the underdog.

National Underdog Day was first observed in 1976.

National Flashlight Day - Day of Winter Solstice


National Flashlight Day is on the same day as Winter Solstice, the shortest day of the year.

It was around 1899 that the invention of the dry cell and miniature incandescent electric light bulbs made the first battery-powered flashlights possible.

Today the flashlights that we use, are mostly incandescent lamps or light-emitting diodes and run on disposable or rechargeable batteries.  Some are powered by the user turning a crank or shaking the lamp and some have solar panels to recharge a battery.

In addition to the well known, general-purpose hand-held flashlight, other forms have been adapted for special uses.  Head or helmet-mounted flashlights designed for miners and campers leave the hands free.  There are special flashlights that can be used underwater or in flammable atmospheres.

January 10, 1899 – British Inventor David Misell obtained U.S. Patent No. 617,592, assigned to American Electrical Novelty and Manufacturing Company.  This electric device designed by Misell was powered by “D” batteries laid front to back in a paper tube with the light bulb and a rough brass reflector at the end.  The company donated some of these devices to the New York City police, who responded well to them.

National French Fried Shrimp Day - December 21


National French Fried Shrimp Day is observed annually on December 21

Americans eat more shrimp than any other seafood.

The word prawn is used loosely to describe any large shrimp, sometimes known as jumbo shrimp.   Some countries use the word prawn exclusively for all shrimp.

Preparing the shrimp for consumption usually involves the removal of the head, shell, tail and sand vein.  There are many ways to cook shrimp. Common methods of preparation include baking, boiling, broiling, sauteing, frying and grilling.

Cooking time is delicate for shrimp and they are at their best when not over cooked.

A healthy food, shrimp is low in calories and high in levels of omega-3s, calcium, iodine, and protein.  Shrimp is also known to be considered good for the circulatory system.   *The preparation of the shrimp does impact the caloric count.

National Maine Day - December 21


On December 21, National Maine Day recognizes the 23rd state to join the union and the most eastern one, too!

Populated by Wabanaki tribes when European explorers first arrived, Maine would later be colonized by French and English settlers, leaving Maine’s possession in constant debate. Fast forward to 1820; the state was carved out of Massachusetts as part of the Missouri Compromise.

Today, with her rocky shores and idyllic New England backdrop, Maine allows a moment to experience the light and sounds at a pace that’s more natural. Lobster, once so abundant it was served to prisoners and servants, is now a delicacy and just one of Maine’s many ocean delights.

Artists flourish in Maine. From fiction to landscapes, the state has inspired poets, writers, painters and more for centuries. From the Acadia to Kennebunk, from the highlands to the valleys, Maine is open all year round.
