Hanging Stockings

While there’s no official record of why we hang socks for Santa, one of the most plausible explanations is that it’s a variation on the old tradition of leaving out shoes with hay inside them on December 5, the eve of St. Nicholas’s feast day. Lucky children would discover that the hay they left for St. Nick’s donkey had been replaced with treats or coins when they woke up the next morning. Another story says that St. Nicholas learned of a father who was unable to pay for his three daughters’ dowries, so St. Nick dropped gold balls down a chimney, which landed in stockings hung by the fire to dry. But this appears to be a modern telling—traditional versions of the story generally have the gold land at the father’s feet after being thrown through a window.

Regardless of what started the tradition, people seem to have realized the need to use a decorative stocking in place of an actual sock pretty early on. In 1883, The New York Times wrote:

“In the days of the unobtrusive white stocking, no one could pretend that the stocking itself was a graceful or attractive object when hanging limp and empty from the foot of the bedstead. Now, however, since the adoption of decorated stockings ... even the empty stocking may be a thing of beauty, and its owner can display it with confidence both at the Christmas season and on purely secular occasions.”

Caroling

Though it may seem like a centuries-old tradition, Time reports that showing up at people’s houses to serenade them with seasonal tunes only dates back to the 19th century. Before that, neighbors did visit each other to impart wishes of good luck and good cheer, but not necessarily in song. Christmas carols themselves go back hundreds of years, minus the door-to-door part. The mashup of the two ideas didn’t come together until Victorian England, when caroling was part of every holiday—even May Day festivals. As Christmas became more commercialized, caroling for the occasion became more popular.

Using Evergreens as Christmas Trees

Before Christianity was even conceived of, people used evergreen boughs to decorate their homes during the winter; the greenery reminded them that plants would return in abundance soon. As Christianity became more popular in Europe, and Germany in particular, the tradition was absorbed into it. Christians decorated evergreen trees with apples to represent the Garden of Eden, calling them “Paradise Trees” around the time of Adam and Eve’s name day—December 24. Gradually, the tradition was subsumed into Christmas celebrations.

The tradition spread as immigrants did, but the practice really took off when word got around that England’s Queen Victoria decorated a Christmas tree as a nod to her German husband’s heritage (German members of the British royal family had previously had Christmas trees, but they never caught on with the wider public). Her influence was felt worldwide, and by 1900, one in five American families had a Christmas tree. Today, upwards of 30 million real Christmas trees are sold in the U.S. every year.

The Colors Red and Green

As with many other old Christmas traditions, there’s no hard-and-fast event that deemed red and green the Official Colors of Christmas™. But there are theories—the green may have derived from the evergreen tradition that dates back to before Christianity, and the red may be from holly berries. While they’re winter-hardy, just like evergreens, they also have a religious implication: The red berries have been associated with the blood of Christ.

Ugly Christmas Sweaters

To celebrate this joyous season, many people gleefully don hideous knitwear adorned with ribbons, sequins, bows, and lights. In the past, the trend was embraced solely by grandmas, teachers, and fashion-challenged parents, but in the last decade or so, the ugly sweater has gone mainstream. We may have Canada to blame for that: According to the Ugly Christmas Sweater Party Book, the ugly sweater party trend can be traced to a 2001 gathering in Vancouver.

Leaving Milk and Cookies for Santa

When we plunk a few Oreos or chocolate chip cookies on a plate for St. Nick, accompanied by a cold glass of milk, we’re actually participating in a tradition that some scholars date back to ancient Norse mythology. According to legend, Odin had an eight-legged horse named Sleipnir. Kids would leave treats for Sleipnir, hoping that Odin would favor them with gifts in return. The practice became popular again in the U.S. during the Great Depression, when parents tried to impress upon kids the importance of being grateful for anything they were lucky enough to receive for Christmas.

The A Christmas Story Marathon on TBS

If one of the highlights of your holiday is tuning in for 24 hours of watching Ralphie Parker nearly shoot his eye out, you’re not alone—over the course of the day, millions of viewers flip to TBS. The marathon first aired on TNT in 1997, then switched to sister station TBS in 2004.

Yule Logs

Throwing a yule log on the fire is another tradition that is said to predate Christianity. As part of winter solstice celebrations, Gaels and Celts burned logs decorated with holly, ivy, and pinecones to cleanse themselves of the past year and welcome the next one. They also believed the ashes would help protect against lightning strikes and evil spirits. The practice was scaled down over time, and eventually, it morphed into a more delicious tradition—cake! Parisian bakers really popularized the practice of creating yule log-shaped desserts during the 19th century, with various bakeries competing to see who could come up with the most elaborately decorated yule log.

If you prefer a wood yule log to one covered in frosting, but find yourself sans fireplace, you can always tune in to Yule Log TV.

Advent Calendars

Technically, Advent, a religious event that has been celebrated since the 4th century, is a four-week period that starts on the Sunday closest to the November 30 feast day of St. Andrew the Apostle. Traditionally, it marked the period to prepare for Christmas as well as the Second Coming. These days, it’s mostly used as a countdown to Christmas for the religious and the non-religious alike.

The modern commercialized advent calendar, which marks the passage of December days with little doors containing candy or small gifts, are believed to have been introduced by Gerhard Lang in the early 1900s. He was inspired by a calendar that his mother made for him when he was a child that featured 24 colored pictures attached to a piece of cardboard. Today, advent calendars contain everything from candy to LEGOs.

Eggnog

It’s hard to imagine why anyone would be inspired to chug a raw egg-based drink, but historians agree that ’nog was probably inspired by a medieval drink called posset, a milky drink made with eggs, milk, and sometimes figs or sherry. These were all pricey ingredients, so the wealthy often used it for toasting.

Eggnog became a holiday drink when colonists brought it over from England, but they found a way to make it on the cheap, nixing the figs and substituting rum for sherry. And how about that weird nog name? No one knows for sure, but historians theorize that nog was short for noggin, which was slang for a wooden cup, or a play on the Norfolk variety of beer also called nog (which itself may be named after the cup).

Mistletoe

Mistletoe has been associated with fertility and vitality since ancient times, when Celtic Druids saw it as such because it blossomed even during the most frigid winters; the association stuck over the centuries.

It’s easy to see how fertility and kissing can be linked, but no one is quite sure how smooching under the shrub (actually, it’s a parasitic plant) became a common Christmas pastime. We do know the tradition was popular with English servants in the 18th century, then quickly spread to those they served. The archaic custom once allowed men to steal a kiss from any woman standing beneath; if she refused, they were doomed with bad luck.

Christmas Cards

Exchanging holiday greetings via mail is a surprisingly recent tradition, with the first formal card hitting shelves in 1843. Designed by an Englishman named J.C. Horsley, the cardboard greeting showed a happy group of people participating in a toast, along with the printed sentiment, “A Merry Christmas and a Happy New Year to you.” A thousand of them were printed that first year, and because it cost just a penny to mail a holiday hello to friends and family (the card itself was a shilling, or 12 times as much), the cards sold like hotcakes and a new custom was born. Today, Americans send around 2 billion cards every year.
