Samsung's stock Clock app has this function.

Oh the horror.

Nice jingoism.

I've never once had a problem managing my alarm clock for my days off (though it's a neat idea).

Your whole "Americans don't sleep" nonsense is just that, ignorant nonsense. Maybe take this political bullshit somewhere else, not this post.

Instead, perhaps, email the dev and do the legwork to get this feature, that only you seem to want, added. I do this all the time. Funny, it takes effort on my part to get features, instead of complaining and condemning people.

MANY devs aren't American, so you're insulting them.
