Where the World Gathers to Celebrate Every Day

DAY OF THE PROGRAMMER – 256th Day of the Year

Day of the Programmer 256th Day of the Year


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.


Pay tribute to programmers and Post on social media using #DayoftheProgrammer to show your appreciation.


In 2002, Russian programmers Valentin Balt and Michael Cherviakov of Parallel Technologies gathered signatures in the hope the Russian government would declare Day of the Programmers.  It wasn’t until 2009 that the Ministry of Mass Media and Communications of Russia announced the official holiday in honor of computer programmers.  The bill was signed on September 11, 2009, by President Dmitry Medvedev of Russia.

There are over 1,200 national days. Don’t miss a single one. Celebrate Every Day with National Day Calendar!
