That’s actually why I think it so important to resist the trend of the world to celebrate the holiday before the holiday, so that when the Day comes, it comes, not as joy, but merely as relief that the particular strains and demands we perceive it to place on us will soon end. (Or why observing the fast that precedes it as best you can is so good for attuning us to the joy of the Holiday, so that it is fresh and new.)
It’s also understandable that you wouldn't want to celebrate the same holiday twice on both calendars. (There’s a line from Lewis’s “Perelandra” about it being really possible (as Fallen beings) to have too much of a good thing.) it’s hard enough on someone like me, caught between cultures, and trying to continue to bask in and be part of my native culture, and share it, at least as much as I can, with my children, who are now mostly at an age when they want to resist and rebel against any good guidance from Dad, when the competing culture (Russian) absorbs most of their time and attention.
