The Women's International Democratic Federation (WIDF) is an international women's rights organization. Established in 1945, it was most active during the Cold War when, according to historian Francisca de Haan, it was "the largest and probably most influential international women's organization of the post-1945 era". Following the dissolution of the Soviet Union in 1991, its headquarters were moved from Berlin to Paris. In 2002, with the election of Márcia Campos as president, the office relocated to Brasília. Subsequently, in 2007 the WIDF secretariat was located in São Paulo. Since 2016, the president has been Lorena Peña of El Salvador. The WIDF's magazine, Women of the Whole World, was published in six languages: Arabic, English, French, German, Russian, and Spanish.

Children's Day is a commemorative date celebrated annually in honor of children, whose date of observance varies by country. In 1925, International Children's Day was first proclaimed in Geneva during the World Conference on Child Welfare. Since 1950, it is celebrated on June 1 in many Second World countries. World Children's Day is celebrated on 20 November to commemorate the Declaration of the Rights of the Child by the UN General Assembly on 20 November 1959. In some countries, it is Children's Week and not Children's Day. The Sikhs celebrate Children Day on 20 December to 27 December. In the U.S., Children's Day is celebrated on the second Sunday of June.
