St. Cyril's and St. Methodius' day

St. Cyril's and St. Methodius' Day celebrates the lives of Saints Cyril and Methodius, two brothers who were 9th-century Byzantine missionaries. They are renowned for developing the Glagolitic alphabet, the first script used to write Slavic languages, helping spread Christianity and literacy among Slavic peoples. Their work laid the foundation for the Cyrillic alphabet, which is still used today in many Slavic nations. The day honors their contributions to language, culture, and religion, recognizing their role in fostering communication and education across Eastern Europe.
