Vespers is the sunset evening prayer service in the Orthodox, Western and Eastern Catholic, Anglican, and Lutheran liturgies of the canonical hours. The word comes from the Greek ἑσπέρα ("hespera") and the Latin vesper, meaning "evening". It is also referred to in the Anglican tradition as evening prayer or evensong. The term is also used in some Protestant denominations (such as the Presbyterian Church and Seventh-day Adventists) to describe evening services.
