Orthodox religious commemorations and feast days

Various Orthodox Christian religious observances and historical commemorations are noted for late September.

In Greece, significant attention is given to the Panagia Myrtidiotissa, the patron saint of Kythera. Tradition holds that her miraculous icon was discovered in a myrtle bush by a shepherd in the 14th century. Celebrations include liturgical services and processions, particularly in Kythera and Pylos.

Other notable commemorations include Saint Thecla, recognized as the first female martyr and an 'equal-to-the-apostles' for her devotion following the teachings of Saint Paul. Additionally, the memory of Saint Euphrosyne is honored, noting her life of asceticism and her decision to live as a monk named Smaragdos to serve the poor.

In Romania, services are held to honor Saint Siluan the Athonite at the Muntele Rece Monastery, emphasizing themes of spiritual peace and humility.
