Philippine presidential inauguration

The inauguration of the president of the Republic of the Philippines is a ceremony marking the commencement of the six-year term of a president of the Philippines, who is both head of state and head of government. The inauguration is performed on June 30, as mandated by the 1987 Constitution. Under the older 1935 Constitution, the date was December 30, which is also Rizal Day; the last inauguration held on the older date was Ferdinand Marcos' second one on December 30, 1969. The most recent public presidential inauguration ceremony was that of President Bongbong Marcos, who began his six-year term in office on Thursday, June 30, 2022.

The only inauguration element mandated by the Constitution is that the president-elect takes the oath, or makes an affirmation, before that person can "enter on the execution" of the office of the presidency. Over the years, various unofficial traditions have arisen that have expanded the inauguration from a simple oath-taking ceremony to a day-long event, including parades, speeches, and balls.

When a new president takes over mid-term due to the death, resignation, or deposition of another president, the oath of office is administered as soon as possible, and due to the sudden nature of such an event, formal public celebrations are not held.
