Day of Remembrance for All Victims of Chemical Warfare

This commemoration provides an opportunity to pay tribute to the victims of chemical warfare, as well as to reaffirm the commitment of the Organisation for the Prohibition of Chemical Weapons (OPCW) to the elimination of the threat of chemical weapons, thereby promoting the goals of peace, security, and multilateralism.

United Nations, Day of Remembrance for all Victims of Chemical Warfare

This day was originally celebrated on 29 April, because it was on that day in 1997 that the Chemical Weapons Convention came into force. The Conference of States Parties to the Convention (those countries that have ratified the Convention and are therefore bound by it) later decided to observe the day on 30 November or the first day of the regular session of the Conference. So the Day can move about from time to time. Find out more here.
