Freedom Day, 18 March, was a Republic of the Sphere holiday commemorating Devlin Stone's escape from a Word of Blake reeducation camp on Kittery.
Shortly after the establishment of the Republic, calls for a holiday honoring Devlin Stone began. Senator Leslie Brahe spearheaded the effort, beginning in 3086 with a proposal for a holiday commemorating Stone's birthday - a proposal Stone rejected both out of opposition to a holiday and due to not having a known birthday. Undeterred by Stone's opposition to a holiday, Brahe organized a grassroots movement across the Republic to commemorate Stone's Kittery escape, and by 3100, all Republic worlds recognized Freedom Day in some form.
After Stone's retirement, his successor as Exarch, Damien Redburn, formally recognized Freedom Day on 18 March 3131. With recognition came standardization. Under Redburn, the official cross-Republic Freedom Day procedures included morning parades, afternoon speeches and tri-vid programs, and an evening fireworks and laser show accompanied by joyous music.
