Programmer’s Day is observed in China every October 24, a date chosen for its representation of the binary prefix "Ki" (kibi), corresponding to 1024 (2 to the tenth power). This holiday has been celebrated since at least 2010 and acknowledges the contributions of programmers, who are essential in the software industry. On this day, various events such as exhibitions, technology conferences, workshops, coding competitions, and awards ceremonies are organized by Chinese IT companies and international firms with offices in China. These activities provide opportunities for programmers to exchange ideas and showcase their work. While the more widely recognized Programmer’s Day is celebrated on September 12 or 13, the Chinese version emphasizes the significance of the number 1024 in computing.
