September 11 is a special non-working holiday in the province of Ilocos Norte. The day is observed annually to commemorate the birth anniversary of Ferdinand E. Marcos, the 10th President of the Philippines, who was a native of the province.
The legal foundation for this observance is Republic Act No. 11043, which officially declares September 11 of every year as "President Ferdinand E. Marcos Day" in Ilocos Norte. As a special non-working holiday, its rules differ from those of a regular holiday. While work is suspended, employees required to report for duty are entitled to premium pay, typically an additional 30% of their daily basic wage for the first eight hours of work.
The practical application of this law means that on this date, local government offices, public and private schools, and most businesses within Ilocos Norte are closed. This allows the residents of the province to participate in ceremonies and activities organized to celebrate the occasion. The holiday is strictly provincial and is not recognized or observed in other parts of the Philippines.
