A calendar is a collection of days and dates humans use to guide their daily activities. The Ethiopian calendar system is significant in the socio-cultural lives of the Ethiopian people, who aspire to live peaceful lives. They believe the universe will be harmonious when people can coexist peacefully with God, one another, and the universe in a balanced way.
