Programmers Day – September 13, 2024

Programmers Day is celebrated on September 13, or the 256th day of the year. The day honors programmers and innovators who make our lives easier by innovating and designing programs. The day is also known as International Programmers Day, and its celebration is actually based on the binary code! Every programmer knows that 256 is a special number. It is represented by an eight-bit byte 256 equals 2 to the eighth power. This digit makes it the highest power of two that is less than 365. When translated to binary code, the day reads 1 0000 0000. How cool is that!

History of Programmers Day

In 2002, Russian programmers Valentin Balt and Michael Cherviakov of Parallel Technologies got people together and gathered signatures to urge the Russian government to declare Day of the Programmers. But it wasn’t until 2009 that the Ministry of Mass Media and Communications of Russia recognized Programmers Day as an official holiday. The bill in honor of computer programmers was signed by President Dmitry Medvedev on September 11, 2009. The day is also celebrated on different days in different countries. In China, Programmers Day is October 24, which has been in existence for a long time now. The date was chosen because it can also be written as 1024, which is equal to 210. In real life, 1024 is usually being treated as 1000, as an interface between binary codes and the decimal world. The day remains consistent regardless of leap years. Before September 13, people unofficially celebrated Programmers Day on January 7. The January 7 celebrations have now become rare.

Programmers Day honors programmers around the world. There is hardly anyone in the modern world who does not benefit from the services of a programmer. Be it transportation or medicine, finance or education, programming is essential to the smooth functioning of every service. Almost all major businesses require programmers to maintain their IT infrastructure. Telecommunications is also heavily reliant on programmers. The automobile industry needs programmers for the smooth functioning of the assembly lines. Programmers also help with maintaining security, society, and entertainment. We need programmers for the latest in protection, design, and innovation.
