Is this timed so that everyone in the US will have a view on the evening of July the 4th or is it in the morning ?

If NASA screwed up the miles and km then it could happen in the middle of the daytime. The only viewers then will be on the other side of the planet!

Yes. The next stage for NASA is to make sure there are no clouds over America that night.
