National Teachers' Day is observed in Indonesia every November 25, commemorating the anniversary of the establishment of the Indonesian Teachers Association (Persatuan Guru Republik Indonesia, PGRI). This day was established by the President of Indonesia in 1994 and later confirmed by a governmental act in 2005. Although it is not a public holiday, schools across Indonesia typically hold special memorial ceremonies attended by teachers, principals, and school supervisors. These ceremonies emphasize the vital role of teachers in the nation's development, recognizing them as unsung heroes. Students are encouraged to prepare special shows or present treats to express their gratitude for their teachers' hard work.
