In Advent, the Joyful Mysteries are a natural companion any day.

“This is my body which is given for you. Do this in memory of me.”Luke 22:19
At the Last Supper, on the night before He suffered, Jesus takes bread and wine and gives His Body and Blood to the apostles as food and drink, the new covenant in His Blood.
Fruit of the mystery: Adoration
“O Dayspring” — the O Antiphon for December 21
O Dayspring, splendor of eternal light and sun of justice: come, and enlighten those who sit in darkness and the shadow of death.
Roman Breviary, Magnificat antiphon (translated for this app)
