Thanks for the clarification on the Orthodox calendar. Very enlightening, and I actually think that we Latins could do well to "localize" our calendar a little better. Why the feasts of St. John Neumann, St. Katharine Drexel and the North American Martyrs are not major feast days in the U.S. is utterly beyond me.
What "drives" the names and ranks of saints on our calendars is mostly sustained local veneration. The reason that a given saint is on the local calendar is not so much that because he was a local as it was that he is venerated locally.
The Orthodox Typikon always gives great latitude to the parish rector in determining which of the saints falling on that day in the calendar will be commemorated in the services on that day.
