A procession was held in the capital, Abuja, with girls taking part to represent missing girl, BBC reported on Tuesday.
Schoolgirls were kidnapped by militant organisation Boko Haram on April 14 last year. The incident evoked global outrage. US and China even promised help to rescue them.
Nobel Peace Laureate Malala Yousafzai has criticised Nigerian and world leaders for not doing enough to save the girls. In an open letter to the girls, Malala writes: "In my opinion, Nigerian leaders and the international community have not done enough to help you."
Launched in 2002, Boko Haram - which in the local Hausa language means "Western education is forbidden", a reference to the initial focus of its Islamist agenda - became a force to be reckoned with in 2009 when it raided police stations and government buildings in Maiduguri, and other northern cities.
US State Department added Boko Haram in terrorist organisation in November 2013.
