Programmers' Day is celebrated around the world on the 256th day of each year, i. e. September 13 or September 12 in leap years. 256 was chosen as it is the number of distinct values that can be represented with an eight-bit byte.
If you're friends with a programmer and want to make their programmers day, check out these gift ideas, including posters, mugs, t-shirts and more, that you can buy from Amazon, Redbubble or Zazzle.
