Recognized annually, Wikipedia Day is a celebration held in honor of the foundation of Wikipedia, the free, global, and online encyclopedia that was established on the 15th of January, 2001.

This day is observed by those who utilize, contribute to, and support the platform. The aim is to acknowledge the significant roles Wikipedia plays in the global spread of information and knowledge. The day also serves to honor the multitude of volunteers from different backgrounds who tirelessly contribute content in various languages to the platform.

History of Wikipedia Day

The idea of creating Wikipedia was first proposed by Larry Sanger and Jimmy Wales in 2000. Their vision was to establish an internet-based encyclopedia that anyone could edit and access for free. So, on January 15, 2001, the inaugural version of Wikipedia was launched. Initially, it began as an encyclopedia in English, but it wasn’t long before editions in other languages began to emerge.

In the early days, there were many skeptics who doubted the viability of an open-source encyclopedia platform. Concerns were raised over the issue of accuracy due to the potential for vandalism and misuse. However, Wikipedia proved these skeptics wrong over time, emerging as both a trusted and valuable resource. The community of Wikipedia volunteers grew exponentially, with individuals from all corners of the globe adding and contributing to the collection of articles on a myriad of topics.

Fast forward to 2003 and the formation of the non-profit organization, the Wikimedia Foundation. This organization took on the responsibility of managing Wikipedia and its associated projects. By 2023, Wikipedia boasts more than 6.7 million English articles and operates in over 300 different languages.

The festivities surrounding Wikipedia Day have varied throughout the years. Some years, the Wikimedia Foundation hosted celebrations at its San Francisco headquarters. Other years, local Wikipedians would organize meetups in their respective cities. These celebrations often feature cake, speeches, and discussions about the future trajectory of Wikipedia. In addition, individuals around the globe celebrate online by creating new articles or enhancing existing ones.
