“Now therefore, I, William Samoei Ruto, President and Commander-in-Chief of the Kenya Defence Forces, by the authority vested in me by the Constitution, do hereby proclaim that 27th August, 2025, and every 27th Day in the Month of August forever thereafter shall be observed as “Katiba Day” in commemoration of the promulgation of the Constitution of Kenya 2010,” read the presidential proclamation in part.

President Ruto noted that Katiba Day will be observed across the Kenyan territory and in all the Kenyan Diplomatic missions abroad.
“Katiba Day shall be observed throughout the territory of Kenya and 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,” he stated.
Further, President Ruto mentioned that Katiba Day will remain a working day in the country.
He directed all government institutions in the three arms of government and the two levels of governance, including schools, to organize, hold, and participate in solemn civic activities on August 27 to foster constitutional awareness and civic engagement.
The constitution was promulgated on August 27, 2010, during the late President Mwai Kibaki’s administration.
This was after it was subjected to a referendum on August 4, 2010, and was approved by 67% of Kenyan voters.
The 2010 constitution created 47 county governments, each with its own governor, assembly, and executive.
It also created a bicameral parliament; the National Assembly and Senate, with the National Assembly representing constituencies and special interests, while the Senate protects devolution.
