World Computer Day

The Theme for World Computer Day 2025- The Burroughs Corporation of Paoli, Pennsylvania

World Computer Day is an annual celebration of computing and the people who make IT happen.

Each year has a new theme, new events, new resources, and new friends to be made!

Like "Earth Day", this is a distributed event with people celebrating all over the world in their own location.

There's much to celebrate this year for World Computer Day, but nothing more important than the celebration of the wizards who brought us next generation computing technologies right after the launch of the ENIAC.

Last year, 2024 the theme was "The Big Three Computing Advances"

Storage, Tubes-To-Transistors, Whole Computing

Prior year February 15th, 2023 the theme was the Eckert-Mauchly Computer Corporation, the worlds first company set up to develop commercial, all-electronic computing devices.

Prior year, February 15, 2022 the theme included a deep dive into the revolutionary 6502 chip; the chip that changed the world, created in Valley Forge, Pennsylvania!

Prior to that, on February 15, 2021, we celebrated the ENIAC on World Computer Day; the 75th anniversary of the world's first all-electronic, programmable computer, the ENIAC at www.ENIACDay.org web site.

Take your time, look around, and learn all there is to know about the World Computer Day celebrations on February 15th, each year.

We hope you enjoy the celebration!

Philadelphia and the Birth of the Computer Age

Philadelphia and the Birth of the Computer Age, an article by Paul Ceruzzi

We take the date for World Computer Day from the date in which the ENIAC was started back in 1946. This first "all electronic, programmable" computer set the stage for an explosion of all-electronic computing on into the next century. The ENIAC was big. The initial proposal, for a device containing about 5,000 vacuum tubes, grew to a final count of around 18,000 tubes.
