A street vendor plugs in decorations for Ramadan in Amman, Jordan, Thursday, July 19, 2012. Religious authorities in Jordan declared that Friday will be the start of the holy month of Ramadan, a period devoted to dawn-to-dusk fasting, prayers and spiritual introspection. Ramadan begins around 11 days earlier each year. Its start is calculated based on the sighting of the new moon, which marks the beginning of the Muslim lunar month that varies between 29 or 30 days.
