Each year, Day of the Programmer is observed on the 256th day of the year.
Also known as International Programmers Day, this day is celebrated based on binary code. The number 256 is distinct to programmers. Represented by an eight-bit byte 256 equals 2 to the eighth power. This makes it the highest power of two that is less than 365. Translated to binary code, the day reads 1 0000 0000.
