Since 1959 the UN has designated International years in order to draw attention to major issues and to encourage international action to address concerns which have global importance and ramifications.
There is a concerted effort not to designate every year - for fiscal reasons and to avoid any process of trivialization. The following is the chronological list of years designated to date:
