Satu Suro

Satu Suro (Javanese: , ) is the first day of the Javanese calendar year in the month of Suro (also transcribed "Sura"), corresponding with the first Islamic month of Muharram. It is mainly celebrated in Java, Indonesia, and by Javanese people living elsewhere.
"Satu Suro" has numerous associations in Javanese folk tales and superstitions in Java that vary considerably through regional variation in cultural practices. The prevalent theme of most "Satu Suro" superstitions is the danger of going out from home, similar to the Balinese holiday of silence, "Nyepi".
An Indonesian film, "Malam Satu Suro", explores the dangers and superstitions about leaving home on the night of "Satu Suro".
