Constitution Day is observed in the Federated States of Micronesia every May 10. This public holiday commemorates the ratification of the constitution in 1979, marking the transition of Micronesia from a trusteeship under the USA to independence. The Federated States of Micronesia consists of four states: Yap, Pohnpei, Kosrae, and Chuuk, each with its own constitution and independent governance. The day celebrates the establishment of a democratic system where each state elects a senator to serve a four-year term, and the Congress, elected by popular vote, chooses the President and Vice President. The observance highlights the significance of self-governance and the historical journey of Micronesia towards autonomy.
