4th of July for everyone, except for Americans

Our son came to me this morning, and asked me this:

Is it the 4th of July for everyone, or just in America?

Me: Well, everyone has the 4th of July. It’s just a bigger deal for people in the United States.

I checked my watch, and noticed that it was 06:49 (we’re UTC+3)

Me: Actually, it’s the 4th of July for everyone except people in the Americas. For them, it’s still 3 July for another 10 minutes or so. Time zones!
