Executive TL;DR30s read

Today marks Programmer's Day, the 256th day of the year, symbolizing the importance of programming in the modern world.

Programmer's Day
The 256th day of the year is chosen for a reason: The date of the holiday is explained by the calculation: 2 (binary system) raised to the power of 8 (the number of bits in a byte). That is, 2^8 = 256. Therefore, in a common year, Programmer's Day is celebrated on September 13, and in a leap year — on September 12.

Happy holiday, colleagues! 😊
