President William Samoei Ruto has officially designated 27th August of every year as Katiba Day in commemoration of the promulgation of Kenya’s 2010 Constitution.
In a presidential proclamation issued on 25th August 2025, the Head of State noted that the adoption of the Constitution 15 years ago was a historic milestone that reshaped Kenya’s governance, strengthened devolution, entrenched constitutionalism, and guaranteed fundamental rights and freedoms.
“Katiba Day shall be observed throughout the territory of Kenya and in all our diplomatic missions abroad as a day dedicated to renewing our shared commitment to the ideals of our Constitution by fostering national dialogue on constitutionalism, governance, and the rule of law,” the proclamation reads in part.
However, the President clarified that Katiba Day will remain a working day, with government institutions, schools, and other public agencies required to organize civic activities aimed at enhancing constitutional awareness and civic engagement.
The proclamation comes as Kenya prepares to mark the 15th anniversary of the Constitution on 27th August 2025. President Ruto emphasized that the day should serve as a reminder of the collective duty of Kenyans to protect, preserve, and fully implement the supreme law of the land.
The Constitution of Kenya 2010, promulgated during President Mwai Kibaki’s administration, is widely regarded as one of the most transformative legal charters in Africa, having introduced devolution and far-reaching reforms in governance and justice.
