Second Sunday in February Norway
February 2 Greece. Corresponds to the Eastern Orthodox feast day of the Presentation of Jesus at the Temple. Since the Theotokos (The Mother of God) appears prominently in this feast as the one who brought Christ to the Temple at Jerusalem, this feast is associated with mothers. However, today many Greeks are beginning to observe Mother's Day as rendered by the West.
