5. The states of Arizona and Oregon both joined the United States on Valentine’s Day
The people of Arizona and Oregon don’t just celebrate love and romance on 14 February. Some extra-patriotic citizens also celebrate their states’ admission to the United States. Arizona became the 48th member of the United States when it joined on Valentine’s Day in 1912. This meant it was the last of the contiguous states to join, with only Alaska and Hawaii coming after. Oregon joined the union way back on Valentine’s Day of 1859.
