World Theatre Day, observed on March 27, is an annual international event dedicated to raising awareness about the art of theatre and its role in cultural and social exchange. This observance was first designated in the Gregorian calendar in 1962, following a decision by the International Theatre Institute, affiliated with UNESCO, to provide a platform for dialogue and cooperation among theatre artists worldwide and to highlight the importance of theatre in cultural and social development. In its inaugural year, the World Theatre Day message was written by Jean Cocteau, a French writer and artist, and this tradition continues today. Each year, a prominent artist from around the world is invited to write a special message for the day, which is read at events worldwide. These messages typically address the significance of theatre in society, the role of artists, and the impact of performing arts on people's lives. In Iran, World Theatre Day is observed with performances, educational workshops, and professional gatherings organized by theatre groups and artistic associations. The day provides an opportunity to focus on the concerns and aspirations of theatre artists and to promote the status of this art form in society. In many countries, theatres hold special events for the public on this day to introduce more people to the world of theatre. This observance was added to the Gregorian calendar as a result of the International Theatre Institute's decision in 1961 and the first celebration held on March 27, 1962, with the aim of honoring and promoting the art of theatre.
