May 2 is Indonesian National Education Day or hari pendidikan nasional abbreviated as HARDIKNAS. It was initiated in remembrance of Ki Hajar Dwantara, the founder of the Taman Siswa education system. His educational philosophy Tut Wuri Handayani means that we can help others learn by coaching and mentoring.
