🇺🇸How does United States mark Cross-border Q&A?

Everyday topic

When you ask about everyday life in the United States, the commonest mistake is assuming a national standard exists. School years are set by districts, marriage by states, addresses need no registration, and most religious observances are not federal holidays — there are in fact very few federal-level rules. So the correct answer to 'how does the United States do it' usually begins with a question back: which state, which district. What can be answered nationally often comes down to eleven federal holidays and a handful of constitutional amendments. If someone gives a single nationwide figure, it is usually a federal holiday or a constitutional-level rule; everything else has to be chased downward.
