Flags are flying in Oregon and Arizona on Valentine’s Day 2018?
It’s statehood day in both of those states.
Legally, nothing stops a resident from flying the U.S. flag following protocol on any day. Yes, you may fly your U.S. flag on Valentine’s Day.
The Flag Code urges flying the flag on the day a state achieved statehood, too.
For Oregon and Arizona, there is an expectation that residents will fly their flags. Oregon came into the union on February 14, 1859; Arizona joined the Republic as a state in 1912.
President William Howard Taft signed the papers accepting Arizona into statehood, on February 14, 1912. He still finished third behind Democrat Woodrow Wilson and Bullmoose Party’s Teddy Roosevelt in that fall’s elections.

Arizona’s state flag waves in the blue – From TripSavvy: On February 14, 1912, Taft signed the proclamation making Arizona the 48th state, and the last of the contiguous states to be admitted to the union. It was the last of the 48 contiguous states to be admitted to the union.
