Antarctica Day is an international holiday recognizing the anniversary of the signing of the Antarctic Treaty in 1959. It is celebrated on December 1 each year. Dedicating Antarctica as a “natural reserve, devoted to peace and science” the Antarctic Treaty is important to the preservation of the continent.
.
Antarctica Day was established by the Foundation for the Good Governance of International Spaces in 2010 as a way to highlight the international cooperation that makes governance of the continent possible and to encourage educators to incorporate Antarctica in their curriculum. 
Antarctica Day was created following the Antarctic Treaty Summit in 2009 on the 50th anniversary of the Antarctic Treaty.
