Executive Secretary Salvador Medialdea signed the proclamation on behalf of President Rodrigo Duterte.

Marcos was born on September 11, 1917 in the Ilocano town of Sarrat.

Duterte, whose late father Vicente served in Marcos' Cabinet, last year authorized the late strongman's burial at the Libingan ng mga Bayani, saying there were no legal impediments to the interment.
