California Admission Day is observed on September 9 each year. It commemorates the day California was admitted into the Union as the 31st state in 1850 after it was ceded to the United States by Mexico in 1848. California became one of the few states to become a state without first being an organized territory. California Admission Day is not a federal holiday. Rather, it’s a local observance in the state, which implies that businesses, schools, and government offices remain open. In times gone by it was celebrated with great pomp and ceremony with parades and pageantry. Though low-key now, the day still marks an important part of Californian history.
