Spreadsheet Day - October 17

Spreadsheet Day

October 17 is Spreadsheet Day. On this day, people share the pros and cons of software designed to create spreadsheets. With their help, the budget and expenses are controlled, shopping lists are compiled and dates of interest are marked. The holiday is associated with spreadsheets: people read about them, write about them, publish designs for spreadsheets.


In 1979, on October 17, the first spreadsheet program VisiCalc appeared. This software has made it easier to manage large amounts of data. VisiCalc was created by Software Arts developer Dan Bricklin, later marking the transformation of the Apple II from a conventional computer to an affordable business tool. The program gained popularity due to the ability to run on a PC, which led to its falling into the hands of small business owners. The modern world is hard to imagine without spreadsheets. They are used for budget management, data sorting, names, number of employees, and so much more.

Interesting facts
