Dragan,

I don't need days for Easter, I need an info on American Holidays. Couple of them have fixed dates and few float, like Columbus Day, for example. I just haven't got used to all these definitions yet...

>I saw the algorithm for calculating the Serbian Orthodox Church Easter (they still use Gregorian calendar internally), but it's based on actual phases of the moon and is not sure to fire right each year, because the priests use their own sideric tables, which were not updated for centuries, and are probably few days in error, compared with the actual moon phases. Thus the actual date of Easter simply has to depend on whatever they print in their calendar. They do include moon phases with the days when they come, but I haven't really checked whether they have it right or not. Easter is on a Sunday, anyway, so it won't hurt your calendar either way.
