December 1 is Mathematics Day in Russia: history, traditions, congratulations

Every year on December 1, Russia celebrates Mathematician's Day, a professional holiday for specialists who have devoted their lives to studying the "queen of all sciences." In 2025, it falls on a Monday. Izvestia tells about the history of the celebration and shares congratulations for mathematicians.

Mathematicians' Day in 2025 — the history of the holiday

Mathematician's Day gained official status quite recently — in 2024. Before that, for more than three decades, it was celebrated informally at the suggestion of students and teachers of Novosibirsk University of the Humanities. In the 1990s, they decided to organize a celebration aimed at popularizing mathematics. April Fool's Day was chosen as the date for it. Thus, the organizers wanted to emphasize that science can be fun and exciting.

In 2023, Viktor Sadovnichy, Rector of Moscow State University (MSU), speaking at the All-Russian Congress of Teachers and Teachers of Mathematics, proposed the establishment of an official Mathematics Day. The congress participants unanimously supported this idea and sent an appeal to the Russian government. Already in July, a new date appeared on the list of professional holidays — the corresponding decree was signed by the head of the Ministry of Education Sergey Kravtsov.

The holiday was timed to coincide with the birthday of Nikolai Lobachevsky, an outstanding Russian mathematician and one of the discoverers of non—Euclidean geometry, on December 1, 1792. His pioneering work has gained worldwide recognition and laid the foundations for many discoveries of the Russian mathematical school. Lobachevsky's theories are still used in aviation, rocket science, cosmonautics, nuclear physics and high-tech medicine.

Traditions of Mathematics Day on December 1st

Despite its "youth", Mathematician's Day has already acquired traditions. On December 1, many educational institutions and scientific organizations hold special lectures and performances dedicated to mathematics.

Various Olympiads, contests, lectures and intellectual games are organized for students and schoolchildren. Many of them take place on the basis of the country's leading universities and schools. Puzzles and quests are particularly popular, which test not only the knowledge, but also the creativity of the participants. These activities contribute to the development of logical thinking and the ability to solve non-standard tasks.

The holiday also provides an opportunity to implement projects and research in various fields of mathematics. The organizers hold exhibitions and festivals featuring interactive exhibits, models, and presentations.

Congratulations on the Day of Mathematics in Russia

On Mathematics Day, congratulations are accepted by all those who have connected their lives with this science: scientists, university professors, school teachers and students. As a rule, they wish them new discoveries, a clear mind, inspiration and strength for new research. Here are some examples of wishes:

"Dear mathematicians! Please accept my most sincere congratulations on your professional holiday! Your work, which requires precision, patience and inspiration, is a real magic that turns numbers into great discoveries. We wish that your equations always converge, and that in life there are beautiful and simple solutions for any problem. I wish you good health, inexhaustible interest in new things and harmony in everything!"

"Happy mathematics Day, virtuoso of numbers and theorems! Let your hypotheses find brilliant evidence, and let your professional successes inspire you to new achievements. I wish you a bright mind, family well-being and great discoveries that will make our world even better and clearer!"

"Congratulations on Mathematician's Day from the bottom of our hearts! Your science is the language spoken by the universe itself, and you are its main translators. May every solved task bring joy, and may inspiration never run out. We wish you good health, personal happiness, and grateful students who will continue the great work of serving this wonderful and accurate science!"

"Please accept my warmest congratulations on your holiday! Mathematics is the poetry of logic, the music of numbers. We wish your life to be like an ideal equation where all variables lead to happiness and well-being. May luck accompany you in every endeavor, and the love and support of your loved ones are always waiting for you at home!"

"I sincerely congratulate you on the Day of Mathematics! Your mind, capable of finding elegant solutions to the most difficult problems, is a real treasure. Let your professional path be as straight as a ray, and in life there will be a place not only for rigorous evidence, but also for pleasant surprises. I wish you bright ideas, loyal friends and confidence in the future!"

Interesting facts about mathematics

In honor of the holiday, Izvestia collected some interesting facts about mathematics.

• The number of possible combinations in a 52-card deck is 52! (factorial). If you write down this whole number, you get an eight with 75 zeros. Therefore, each time the cards are shuffled, there is a high probability that a unique combination will be obtained, which has never been in the universe.
• The world's first female professor of mathematics, Sofya Kovalevskaya, became acquainted with the exact sciences by chance. When she was little, there was not enough wallpaper for her room and the walls were covered with sheets of lectures by mathematician Mikhail Ostrogradsky. At the age of 15, Kovalevskaya began studying differential calculus, and it turned out that many formulas were already familiar to her, because the girl had been looking at them for many years in her bedroom.
• The ability to comprehend "zero" and place it in a numerical series is inherent not only to humans. Scientists have found that the concept of "nothing" is also understood by Rhesus monkeys, chimpanzees and parrots. However, the researchers went further and found out that bees are also capable of this. The insects were taught the concepts of "more" and "less" using sugar syrup and bitter quinine. The bees, having learned to distinguish the numbers from 1 to 4, successfully transferred their knowledge to the numbers 0 and 5. They demonstrated a firm understanding that 0 is less than 1.
• A standard Rubik's Cube can be assembled from any position in no more than 20 moves. The mathematical justification of this principle is called the "God algorithm", and the maximum number of moves is called the "God number". Similar calculations exist for other puzzles — for example, "tag" can be solved in 80 moves.
