We’ve made our very own calendar to count down to Christmas.


Dec 1: Many Different Celebrations

December is here, and the countdown to Christmas has officially started! Did you know that Christmas is celebrated on different dates around the world?

Many people celebrate Christmas and open gifts on the morning of December 25, while other people, like Scandinavians, open their gifts on Christmas Eve.

For hundreds of years, people have been lighting up the darkest time of the year around the December solstice in the Northern Hemisphere—including the ancient celebration of Yule.

Some celebrations even move.

“We’ve started celebrating Christmas on December 25, since we switched from the Julian to the Revised Julian calendar. But we save the gifts for New Year’s Eve,” says our collegue Liuda Drobushenko from Ukraine, explaining that they used to celebrate Orthodox Christmas on January 7 for many years.

Dec 2: Weird Traditions

The holidays are full of traditions—some weirder than others.

For instance, on the evening of December 5, a hairy goat demon called Krampus can be seen in alpine villages throughout southern Germany, Austria, Czechia, Slovenia, and northern Italy.

Santa like we’re often used to seeing him.

In Italy, one of the highlights is a celebration led by the Catholic pope in Rome. He kneels in prayer and gives a floral wreath to Roman firefighters who then lay it at the base of the column with a statue of the Madonna at the Piazza Mignanelli.

Dec 9: Venus and Moon Say Hello

The Moon and Venus are cozying up together in the pre-dawn sky.

Technically known as a conjunction, it is when two astronomical objects appear close to each other in the sky. The celestial bodies involved can be the Sun, the Moon, a planet, or a star.

Although the objects appear to be close, this is an illusion caused by perspective. In reality, however, the two bodies are separated by vast distances. The image is a screenshot from our Interactive Night Sky Map over New York on December 9 at at around 5 am local time.

Our current Gregorian calendar and its predecessor, the Julian calendar, both have 12 months.

However, the month names we use today are derived from the Roman calendar, which initially had only 10 months. “Decem” means ten in Latin, so December was the 10th and last month in the Roman calendar.

Dec 12: A Good Night for Baking and Stargazing

Dec 13: Golden Buns and Garlands

Dec 24: Last Sunday of Advent

Today is the fourth Sunday of Advent and Christmas Eve, and in some cultures, like Scandinavia, this is THE night of celebration.

“My family eats crisp pork belly with red cabbage on Christmas Eve, but because I’m both Norwegian and Australian, we also have turkey on Christmas Day,” says our colleague Anne Buckle.

The fourth Sunday of Advent and Christmas Eve both fall on the same day. This only happens about every six or seven years.
