Runet Day is observed worldwide on April 7, celebrating the introduction of the country code top-level domain (ccTLD) .ru on April 7, 1994. The term "Runet," which refers to the Russian-language Internet, was coined in 1997 by Raffi Aslanbekov and has since become popular among Russian-speaking users. The day acknowledges the significance of the .ru domain and its evolution, including the introduction of the Cyrillic ccTLD .рф in 2009. While there are various definitions of Runet, the most common understanding encompasses all websites available to Russian-speaking users. As of January 2022, there were over 5.3 million domain names under .ru and over 900,000 under .рф, with the Coordination Center for TLD .RU/.РФ serving as the official administrator. This unofficial holiday highlights the cultural and technological impact of the Russian Internet.
