A holiday sure to appeal to some people more than others, Spreadsheet Day commemorates the date that VisiCalc, the first spreadsheet program for personal computers, was released – October 17th, 1979. Since its beginnings, Spreadsheet Day has grown to become a day for celebrating both the advantages and the aggravations of working with spreadsheet software.

The celebration of Spreadsheet Day, like the holiday itself, is enjoyed more by certain types of people. It consists mainly of learning about spreadsheets, reading about spreadsheets, posting or downloading new spreadsheet templates and applications, and wishing a happy spreadsheet day to other celebrants. Some accounting and software companies acknowledge the holiday on their websites. Some suggest using it as a reason to leave work early – perhaps the most popular way to celebrate Spreadsheet Day may be best celebrated by learning some useful computer skills while enjoying a piece of cake.
