About Mindanao Week of Peace

Mindanao Week of Peace is a recurring Philippine peace observance for Mindanao running from the last Thursday of November through the first Wednesday of December.

Its national proclamation history begins in 1999, when Proclamation No. 207 declared November 25 to December 1, 1999 and every year thereafter as Mindanao Week of Peace.

Why Mindanao Week of Peace matters

The observance is intended to encourage a culture of peace, unity and harmony among Mindanaoans regardless of status, religion or culture.

Government agencies, civil society and other groups in Mindanao are encouraged to hold relevant peace activities in coordination with peace-building partners.

History of Mindanao Week of Peace

On November 5, 1999, Philippine Proclamation No. 207 established Mindanao Week of Peace for November 25 to December 1, 1999 and every year thereafter.

On November 3, 2000, Proclamation No. 408 amended the recurring date to the last Thursday of November through the first Wednesday of December.

On November 26, 2001, Proclamation No. 127 retained that recurring rule, superseded Proclamation No. 408 and again directed coordination of peace activities in Mindanao.
