Armistice Day is a holiday celebrated annually on 29 May in the United Empire of Earth (UEE). It was established in SEY 2792 to recognize the 2789 signing of the the Akari-Kr.ē Treaty, which brought about an unofficial resolution to the Xi'an-Human Cold War and contributed to the events that ended the Messer Era. Many businesses in the UEE close during Armistice Day. The holiday is especially popular on Terra (Terra III), the home of Senator Terrence Akari, who authored the treaty in secret with a then-young Emperor T.uēng se Kr.ē.
