Programmers' Day

Computers, technology and software makes the modern world go around – but for every piece of clever software, there’s a programmer (and often teams of programmers) behind the scenes, solving problems with clever code, cloud security solutions, and intense development projects. Spare a thought for these digital pioneers on Programmers’ Day!
Programmers’ Day is celebrated on the 256th day of the year - chosen because this is the number of distinct values that can be represented with an eight-bit byte, and the highest power of two which is less than 365.

Programmers' Day is an international professional holiday, recognized in many technology companies and programming firms, that is celebrated on the 256th (hexadecimal 100th, or the 28th) day of each year (September 13 during common years and on September 12 in leap years). It is also officially recognized in Russia and observed in several other countries, including Israel, Bangladesh, Chile, Brazil, Mexico, Austria, Germany, Canada, China, Croatia, France, Guatemala, India, Belgium, Australia, New Zealand, Poland, Slovenia, the United Kingdom, the United States and Uruguay.
