Spreadsheet Day

Spreadsheet Day is a holiday observed annually on October 17th, celebrating spreadsheets and their value to businesses worldwide.

Although the concept of a spreadsheet program for computers has been around since the 1960s, it wasn’t widely used until the late 1970s when the VisiCalc program was written for the Apple II computer.

Since then, spreadsheet software has become an essential part of any organization that needs to keep track of its finances. It is for this reason alone that this holiday should be given a place on any professional’s calendar of events.

The History of Spreadsheet Day

The first spreadsheet program, VisiCalc, was released in October 1979 for the Apple II computer. This marked the Apple II computer’s transition from being merely a toy for electronic enthusiasts into a powerful computing tool for business.

With the release of this program, homeowners and small business owners could have the same powerful software accounting power that multinational corporations had. In 1979, the holiday Spreadsheet Day was created to celebrate the power of spreadsheet programs and the effect they have had on businesses small and large all over the world.
