Human Rights Shabbat is a T'ruah initiative to educate Jewish communities about the intersection of Jewish values and universal human rights. Last year, over 185 communities throughout North America, Europe, and Israel--including congregations, Hillels, hospitals, and chavgurot--participated.
Human Rights Shabbat is held on the weekends bookending December 10th, International Human Rights Day. In 2014, these are December 5-6 and 12-13. Communities should also feel free to observe Human Rights Shabbat on another date if those weeks aren't practical.
Materials for Human Rights Shabbat will be released in late October. For an idea of the range of materials provided, see this collection of past years' resources, many of which are timeless and still applicable.
