In liturgies ancient and modern it is generally prescribed as the office hymn for Compline, especially during the Trinity season. Not unlike the later Lutheran practice of assigning a hymn of the day to each Sunday and feast day in the church year, the monastic office generally prescribed an office hymn for each hour of daily prayer, such as “Now That the Daylight Fills the Sky” (LSB 870), which is usually assigned to Prime, the prayer office for the beginning of the day. “Before the Ending of the Day” is a perfect fit for Compline, the service at the completorium or completion of the day. It is not difficult to picture a group of monks congregating to close the day in prayer with the following Latin chant:
