Programmer's Day

September 13, Saturday

Programmer's Day (Day of the Programmer) is celebrated on the 256th day of each year. Usually, this is September 13, and in a leap year — September 12. The number 256 was chosen intentionally: it is the maximum number of values that can be represented with one byte (2⁸), and it holds special significance in programming.

Significance of the holiday
This day is dedicated to people who create software, develop algorithms, and maintain modern digital technologies. Programmers play a key role in the development of the information society and ensure the functioning of almost all spheres of life — from business and medicine to entertainment and science.

Celebration traditions
In different countries and communities, programmers celebrate this day in their own way:

* Holding contests and hackathons
* Corporate parties and themed events
* Joking congratulations, memes, and pranks
* Giving commemorative gifts and awards to programmers
