To an extent, I suppose. There is also something to be said for just wanting to get outside. Summers in the pacific northwest are also a lot of really long days.

Just writing that, though, makes me realize that most of the northern sections of the US are inline with what we call western Europe? Would be neat to see this broken down by latitude as a crude cohort check.

Most of the northern sections of the USA are on the same latitude as Southern Europe, reaching at most into South France. Germany, the UK are further north than the 45th parallel.

A lot of Europe experiences longer days than PNW during spring to summer.
