Well, if you're from a Latin Rite background, you will notice that there are different Saint Days and Feast Days on the calendar in the Byzantine Rite. Now in the Ukrainian Church, you'll have even more feast days with the Saints and Martyrs from Kievan-Rus'. So even among those in the Eastern Rite, you'll have flavors of the Byzantine Church that will observe even more saints than in the others, or less, and just the basic saint feasts (by "basic" I'm talking saints days celebrated across the board in all Eastern Rite Churches).
