Beautifully done

Beautiful colors, many countries...

However this should be part of a calendar and task manager which you should develop. Look at Smartime+ calendar,todos,gtd for $10, with drag drop tasks (but add week and month views), and you will become VERY popular.

One Problem: once i initially select United States, next time i run the application, i want to look at other countries holidays, how do i do that, there is no control for that. There should be a drop-down list on the bottom to select country. Upon load the application loads up fast and into the current year calendar, but i want to look at other countries holidays too.
Also: there is a left/right button on top, it should also be a slider control to select next/previous year

Nice: when you click on a holiday it tells you at the bottom: "63 days left".. a nice touch (or also says 2947 days left for year 2017 :-) )
