The Day of Remembrance (DOR, Japanese: 追憶の日, Tsuioku no Hi) is a day of observance for the internment of Japanese Americans during World War II. Events in numerous U.S. states, especially in the West Coast, are held on or near February 19, the day in 1942 that Executive Order 9066 was signed by President Franklin D. Roosevelt, requiring internment of all Americans of Japanese ancestry.
