The Glagolitic and Cyrillic alphabets are the oldest known Slavic languages created by two brothers, Cyril and Methodius, in order to translate the Bible and other texts. The brothers became known as the "Apostles of the Slavs" and are still highly regarded by both Roman Catholic and Orthodox Christians.
Several dates are celebrated for the brothers, such as February 14th in the Roman Catholic Church for Saint Cyril's death, and May 24th in the Eastern Orthodox religion in honor of the first recorded celebration in the Bulgarian town of Plovid in 1851. Some also celebrate on July 7th in accordance with the old sanctoral calendar that existed before the revisions of the Second Vatican Council. Monuments and statues of the brothers can be found throughout countries of the former Soviet Union and beyond.
While "Slavonic Literature and Culture Day" is not a public holiday in Russia (as it is in Bulgaria, Slovakia, the Republic of Macedonia, and the Czech Republic), Russians celebrate these saints and the birth of the Cyrillic alphabet with special church services and festivals. Nearly 40,000 people are expected to participate in the procession from the Cathedral of Christ the Savior to Red Square. First celebrated in 1991, this is the only holiday in Russia with both religious and secular meanings.
