MANILA - Malacañang is expected to declare July 6 a national holiday in observance of Eid’l Fitr or the Feast of Ramadan.

In a radio interview, Communications Secretary Martin Andanar said an official announcement may be issued on Monday or Tuesday.

"Napag-usapan namin iyan ni Executive Secretary (Salvador) Medialdea at ito po ay sa July 6. Pero hintayin na lang po natin 'yung opisyal na announcement ngayong darating na Lunes or Martes po," he told state-run dzRB.

Eid’l Fitr, which is celebrated for three days, marks the end of the holy month of fasting for Muslims.

Republic Act No. 9177, signed into law in November 2002 during the Arroyo presidency, declares the first day of Shawwal, the 10th month of the Islamic calendar, a national holiday for the observance of Eidul Fitr.

However, this day is dependent on the Islamic calendar.

According to RA 9177, "the approximate date of these Islamic holidays may be determined in accordance with the Islamic calendar (Hijra) or the lunar calendar, or upon Islamic astronomical calculations, whichever is possible or convenient."

Islam is the second most popular religion in the predominantly Catholic Philippines, with over five percent of the 94 million population practicing the Muslim faith.

Peaceful coexistence between Christians and Muslims has been marred by a decades-old war in Mindanao between Islamic separatist groups and the Philippines government.

The Duterte administration is bent pursuing peace talks with communist and Muslim rebels in the south.
