Mesrop Mashtots Day is celebrated on February 15 each year in Armenia to honor the contributions of Mesrop Mashtots, an Armenian linguist and ecclesiastical leader. He is best known for creating the Armenian alphabet in the early 5th century, which played a crucial role in the development of Armenian literature and culture. The day is marked by various cultural events, including educational programs and discussions about the importance of the Armenian language. It serves as a reminder of the significance of preserving and promoting the Armenian heritage, as well as the impact of Mashtots's work on the Armenian identity.
