The entire month falls within the liturgical season of Ordinary Time, which is represented by the liturgical color green.
This symbol of hope is the color of the sprouting seed and arouses in the faithful the hope of reaping the eternal harvest of heaven, especially the hope of a glorious resurrection. It is used in the offices and Masses of Ordinary Time.
The last portion of the liturgical year represents the time of our pilgrimage to heaven during which we hope for reward.
My heart hath rejoiced in God my Savior, because He that is mighty hath done great things for me.
