In Indonesia, the popular name for Eid al-Fitr at Ramadan’s end is Lebaran. The official or formal expression is commonly Hari Raya Idul Fitri or Idulfitri, while “Lebaran” is the familiar national term used for the celebration and its surrounding holiday period.
Lebaran is associated with returning to one’s hometown, a mass homecoming known as mudik, and with family visits, forgiveness, communal meals, and charitable giving. Indonesian Muslims often practice halal bihalal, a tradition of visiting relatives, elders, neighbors, and colleagues to ask forgiveness and restore harmonious relationships. Festive foods frequently include ketupat, a rice cake wrapped in woven palm leaves, along with dishes such as rendang and opor ayam.
The word’s etymology is debated. It may relate to Javanese lebar, meaning finished or completed, referring to the completion of the Ramadan fast; other proposed links involve abundance, broadness, or overflowing crowds. Technically, Lebaran can also refer more broadly to Eid al-Adha in Indonesia, but in this question’s Ramadan context it conventionally means Eid al-Fitr.
