Fast and Prayer Day is observed in Liberia every second Friday of April and has been celebrated since 1883. This public holiday is a day of religious devotion focused on collective reflection and self-discipline, where Liberians, primarily Christians who make up about 85% of the population, engage in prayer and fasting. While the holiday officially lasts for one day, some individuals extend their observance to an entire week, participating in special church services. The holiday is not celebrated by Liberian Muslims, who dedicate the month of Ramadan to fasting and prayer, and it has historically caused tensions between the two religious groups. In addition to the annual observance, churches in Liberia may also declare special fast and prayer periods for specific occasions.
