Guru Purnima (Hindu)
Guru Purnima is a traditional Hindu, Buddhist, and Jain festival celebrating teachers and spiritual mentors ("gurus"), observed on the full moon day (Purnima) in the month of Ashadha (June–July). It honors the "remover of darkness" (guru), marking the birth anniversary of Veda Vyasa and, in yogic tradition, the day Shiva became the first guru.
