A day honoring various Christian saints in Western and Eastern traditions, paired with Finland's playful National Sleepy Head Day.
Every July 27, Christians celebrate the feast days of saints like Arethas in Western churches and commemorate Aurelius and Natalia of Córdoba, Maurus, Pantalemon, Sergius, Pantaleon, and the Seven Sleepers of Ephesus per the Roman Martyrology.
The Eastern Orthodox liturgics also observe the date with special services honoring local and wider church figures.
Additionally, Finland observes National Sleepy Head Day, a lighthearted tradition where the last person in the household to wake is playfully doused with water or tossed into a lake.
The day also pays homage to Theobald of Marly and Blessed Titus Brandsma, whose contributions to Carmelite spirituality and resistance during turmoil are celebrated.
Communities hold masses, processions, and communal gatherings, blending solemn remembrance of martyrdom with playful customs that foster unity.
