Yes I do. A big part of this stemmed from marital break ups and blended families. For instance, those years my ex husband had my children for Christmas, I would celebrate The Solstice (Dec 21st) instead. My children are Ukrainian by way of their father and his family celebrate Easter on the traditional day which falls two weeks after our Calendar. They are grown now but have incorporated this into their own traditions thus, Easter with me on this calendar and Easter again with them on the slavic calendar. I celebrate Thanksgiving on different days too.
