Liberia's Fast and Prayer Day, observed on the second Friday of April, invites citizens to unite in fasting and prayer for national wellbeing.
Established by government decree, Liberia’s Fast and Prayer Day is a public holiday dedicated to national reflection and spiritual solidarity. Celebrated on the second Friday in April—sometimes as early as April 8—it closes schools, businesses, and government offices. Communities gather in churches, mosques, and open-air venues to fast, pray, and offer thanks for peace and prosperity. The observance encourages citizens of all faiths to petition for the nation’s future and communal harmony. Through collective fasting and worship, the day fosters unity, moral renewal, and hope for generations to come.
