Fun Christmas Facts for Kids
Start here with preschoolers and early readers. These facts are short enough to read aloud in one breath, and most of them lead to a good follow-up question, like “Why would a reindeer need wide feet?” or “Would you want to live in a town called North Pole?” If your child loves animal facts, our fun facts about animals for kids keep the conversation going after the holidays.
1. The word Christmas comes from the Old English “Cristes maesse,” which means “Christ’s mass.”
2. Reindeer are the only deer in which both the males and the females grow antlers. In other deer, only the males do.

4. Reindeer have the widest feet of any deer. Their big hooves work a bit like snowshoes, and in winter, hair even grows between their toes.
5. When a reindeer walks, you can hear a clicking sound. It comes from tendons in the feet sliding over the bones, not from the knees.
6. A baby reindeer, called a calf, can walk within an hour of being born.

12. In Mexico, children break open a piñata filled with candy and toys as part of the Christmas season.
Christmas History Facts
The history of Christmas is older and messier than most of us learned. The Gospel accounts of Jesus’s birth do not give a date, so the December 25 date came later, and different churches settled on different days. These facts stick to what the historical record shows, and they are stated neutrally so families of any background can share them.

15. An ancient Roman almanac shows that Christmas was celebrated on December 25 in Rome as early as AD 336.

19. Many Eastern Orthodox churches celebrate Christmas on January 7.
20. In 1223, Saint Francis of Assisi reportedly set up a stable scene with real people and animals in a church in Greccio, Italy. Manger scenes began in southern Europe.

24. Christmas became a federal holiday in the United States in 1870, during the presidency of Ulysses S. Grant.

How to Use These Christmas Facts With Kids
A list of facts is more fun when it becomes a ritual. A few ideas that work for families with young children:
A fact a day in December: pick 24 facts and read one each morning in December, or tuck one into each pocket of an advent calendar. Our advent calendar ideas include easy formats you can fill with paper slips.
Dinner table round: each person reads one fact and the table guesses whether it is true before hearing the source. For question-and-answer play, try our Christmas trivia page.
Map night: read the around-the-world facts with a globe or a printed map and put a sticker on each country.
Party game: turn a handful of the weird facts into a quick guessing round alongside our Christmas games.
Keep it age-right: toddlers enjoy the reindeer and snow facts with pictures. Save the history and dates for school-age kids, and the authorship mysteries for teens.
Kids who catch the fact bug in December can keep going all year with our fun facts for kids.
Keeping Bedtime Calm in a Busy December
Late parties, travel and excitement about Santa can push bedtimes later night after night. A few habits help little ones keep their sleep on track through the holidays:
Read your nightly Christmas fact during the bath or in pajamas, as part of the usual toddler bedtime routine, rather than as a reason to stay up.
On big days, protect at least one nap, and get back to your normal schedule as soon as you are home.
If your baby sleeps somewhere new, such as a relative’s house, safe sleep rules still apply: alone, on their back, on a firm, flat, bare surface, with no pillows, blankets or bumpers.
Christmas has deep roots, and the most interesting facts are often the true stories behind familiar traditions: a feast date fixed centuries after the event, a tree custom carried from Germany, a Santa Claus pieced together from a saint, a poem and a cartoonist, and a misdialed phone call that turned into a worldwide tradition. Pick a handful that suit your kids’ ages, share them at breakfast or bedtime, and let them ask questions. The best fact is the one that starts a conversation.
Frequently Asked Questions
What are some fun Christmas facts for kids?
Kids love animal and place facts. Both male and female reindeer grow antlers, and the clicking sound reindeer make comes from tendons in their feet. Santa Claus, Indiana, and North Pole, Alaska, are real towns. In Australia and South America, Christmas comes in summer, and in Italy, Befana brings gifts on January 5.
Why is Christmas celebrated on December 25?
The Gospels give no date for Jesus’s birth. The earliest known reference to December 25 is from the year 221, and a Roman almanac shows Christmas celebrated in Rome on that date by AD 336. Some early Christians tied the date to a belief that Jesus was conceived on March 25, nine months earlier.
When did Christmas become a federal holiday in the United States?
Christmas became a federal holiday in 1870, during the presidency of Ulysses S. Grant, according to the Library of Congress. By then, Christmas trees had already become common in the United States, a change the Library of Congress dates to the 1840s. NORAD Santa tracking came much later, in 1955.
Who was the real Santa Claus?
Santa Claus is based on Saint Nicholas, born around the 3rd century in what is now Turkey. His feast day is December 6. Washington Irving wrote about Sinter Klaas in 1809, a poem first printed in 1823 described him dressed in fur, and cartoonist Thomas Nast gave Santa a red coat and a North Pole workshop.
Where did the Christmas tree tradition come from?
The modern Christmas tree seems to have started in medieval Germany, where a decorated paradise tree and a wooden Christmas pyramid with candles merged by the 16th century. German settlers brought the custom to America, Prince Albert helped popularize it in England, and the first known White House tree went up in 1889.
How did NORAD start tracking Santa?
In 1955, a child who had seen a newspaper promotion accidentally dialed the unlisted number of the Continental Air Defense Command in Colorado Springs. Colonel Harry Shoup, on duty that night, assured the caller that Santa would travel safely. NORAD took over the tradition when it was formed in 1958 and now gets more than 130,000 calls a year.
