Early Music Day is celebrated worldwide on March 21, featuring a series of concerts, workshops, conferences, and other events aimed at promoting early music, which includes European Medieval, Renaissance, and sometimes Baroque music. The holiday was launched in 2013 by the European Early Music Network (REMA) and is observed on this date to honor the birthday of Johann Sebastian Bach and to mark the beginning of astronomical spring in the Northern Hemisphere. Events take place simultaneously across Europe, Australia, Canada, Japan, Malaysia, Mexico, South Africa, the United States, and other countries, with many being streamed online for broader accessibility. The celebration has grown from its original focus on Europe, reflecting the universal nature of music. Support for Early Music Day comes from organizations such as the Ministry of Culture of France, the European Broadcasting Union, and the European Commission. Each year, a notable figure from the early music movement is invited to serve as the official ambassador, promoting the appreciation and performance of this historical genre.
