Observed on April 20, is the UN Chinese Language Day. The exact date comes in tribute to Cangjie, the legendary figure credited with having invented Chinese characters. The theme of this year's UN Chinese Language Day is "Highlighting Pictographs," as pictographs are the origin of Chinese characters.
In 2010, the UN Department of Global Communications instituted language days for each of the organization's six official languages. The goal was two-fold: to cel-ebrate multilingualism and cultural diversity as well as to promote the equal use of all six tongues.
