Sources: La Patria and Bolivia public holidays. The Bolivian legislative assembly (Cámara de Diputados) is getting ready to analyze a bill which would make create a new annual public holiday, on June 21, to mark the Indigenous People's New Year (Año Nuevo Indígena), also know as Inti Raymi (celebrated as such as a regional public holiday in Peru). According to the last census (2002), 63% of Bolivians consider themselves to be "indigenous".
Analysis: It is not clear yet, if this holiday would be observed in 2007, or only beginning in 2008. We are monitoring the situation and will report on any decision.
Update: See our follow-up post of June 6.
