International Mother Language Day
In the context of foreign languages and cultures promotion, we would like to inform you that the International Mother Language Day will be celebrated on February 21. This special day was announced in November 1999 by UNESCO and aims to promote and preserve the practice of all languages used around the world and to encourage everyone to multilingualism. The count of all languages spoken in the world is very difficult to achieve, however it is estimated that more than 6000 languages are used!
