Holiday Calculator Sorry, but I guess I know less about Java than I thought I did. I was not able to figure out how to run the program. But it looks like a very capable app.

Wow! That was a lot of work. I am impressed. There are more holidays than I expected. You also included some that most people would not. There is a problem with Easter. It is not in the order by date that the other holidays are listed in. Otherwise, it is a good program.
