Today - 24 May is celebrated the Day of the Slavic script and Bulgarian education and culture. This is one of the largest and brightest holidays, respected by all Bulgarians.

Old saints' lives and Old Bulgarian manuscripts show that the day of the holy brothers has been observed as a church feast since XI century. Both of them are canonized as saints during the IX century for the translation and promotion of the Holy Scripture and of liturgical books in Slavic language. In 1851 for the first time in Bulgaria, in the southern city of Plovdiv, Day of Cyril and Methodius was celebrated, initially as a school and later as a popular holiday of Bulgarian education and culture, informed BNR.

The two brothers created a new Literary Language based on the southwestern Bulgarian dialects, and it turned into the third Literary Language in Europe, along with Latin and Greek. For the creator of the first Slavic alphabet - Glagolitsa is considered the younger of the two brothers Constantine - Cyril The Philosopher. It was created in 855 AC. Later in 863 AC at the request of Prince Rostislav both brothers started teachers activity and distributed the new script and translated by them literature in the land of Velikomoraviya. There, their activity, however, was rebuffed by the German clergy and they were recalled from Velikomoraviya. In 869 AC they headed for Rome where they defended before Pope Adrian II the right to sermonize Jesus Christ' teaching in Slavic language.

After the death of the two equal to the Apostles brothers, their work was continued and completed by their students. However, cruel repression had been taken against them by the German clergy and some of them were killed, others captured, and some of them were forced to flee and seek salvation. Clement, Naum, Sava, Gorazd and Angelariy found good reception on behalf of the Bulgarian ruler Prince Boris I, who provided them conditions to continue their work of teachers. Thanks to the active work of these students of Cyril and Methodius in Bulgaria, our country became the first Slavic cultural center in the Middle Ages, from where the Slavic literacy and literature spread among other Slavic peoples.

Nowadays Cyrillic script is used not only by us, Bulgarians, but also by many other Slavic nations, a total of over 200 million people. Peoples of Iranian, Turk, Caucasian and Mongolian origin also use the Cyrillic alphabet as a basis for their script. Until IXX century it had been used also in Romania. With the admission of Bulgaria into the EU on January 1, 2007, the Cyrillic alphabet, among Latin and Greek alphabet, became the third official script of the European Community. Following the future introduction of the euro as national currency of the country, the on the newly printed euros the word "euro" will be printed in Cyrillic along with Latin and Greek letters.
