Nagy El-Khoury, Maronite and the director of the Alumni Association of Notre Dame de Jamhour College; and Sheikh Mohammad al-Nokkari, former executive director of Dar Al. Fatwa and the head of the Office of Sunni Mufti of the Lebanese Republic, are both activists for Christian-Muslim dialogue in Lebanon. In 2007, thanks to their efforts, 25th March – the Day of the Annunciation of the Blessed Virgin Mary – has become the day of regular meetings between Christians and Muslims in Lebanon and interreligious dialogue throughout a whole region. In 2010 the Day of the Annunciation of the B.V.M, described both in the Bible and in the Koran, was recognized by Lebanese authorities as the Christian-Muslim national holiday. During its celebrations on 25 March 2010, the former President of the Republic of Poland, Lech Wałęsa was its guest of honour.
