Programmer's Day is a professional holiday for programmers, celebrated on the 256th day of the year. The number 256 (28) was chosen because it is the number of distinct values that can be represented using an eight-bit byte. It is also the largest integer power of 2 that is less than 365 (the number of days in a year).
