In Romania, and elsewhere, the 30th of November is the Feast of St. Andrew
. This Apostle's feast is the name day for those called Andrew or Andrea.
From the article:
This Orthodox holiday commemorates Andrew, one of Jesus’ 12 Apostles, the one Jesus called first in their Apostolic endeavor. He was also the first of the Apostles to reach the Dobrogea region of today’s Romania and spread the new religion to this area, creating the first Christian communities here. For this he is seen as Romania’s spiritual patron.
