National FreeBSD Day | June 19
(Last Updated On: November 8, 2022)


National FreeBSD Day on June 19th commemorates the launch date of an innovative technology that many of us use every day.


The open-source operating system called FreeBSD developed out of the University of California at Berkley in 1993. Billions of people around the globe use FreeBSD to teach operating system concepts in universities. Companies also develop products on FreeBSD, and universities use it as a research platform.

While you may not be familiar with FreeBSD, there’s a good chance you’re already using at least some code derived from it in your everyday life. For example, do you stream movies via Netflix? How about chat with friends on WhatsApp? Maybe you play the latest PlayStation 4 game sensation. If so, you’re already using FreeBSD.

As a pioneer in open-source technology, users can modify and redesign FreeBSD to meet their needs, free of charge within the guidelines of the license. Through a network of users, the software keeps pace with today’s technology and prepares us for what’s ahead.
