"A Perfect Day" (first line: "When you come to the end of a perfect day") is a parlor song written by Carrie Jacobs-Bond (1862–1946) in 1909 at the Mission Inn, Riverside, California.[1] Jacobs-Bond wrote the lyrics after watching the sun set over Mount Rubidoux from her 4th-floor room. She came up with the tune three months later while touring the Mojave Desert.[2] For many years the Mission Inn played "A Perfect Day" on its carillon at the end of each day.[3]
