California Admission Day
California Admission Day is a legal holiday in the state of California in the United States. It is celebrated as a day of observance annually on September 9 to commemorate the anniversary of the 1850 admission of California into the Union as the thirty-first state.
California was admitted to the Union as part of the Compromise of 1850 as a free state after being ceded to the United States by Mexico at the end of the Mexican–American War in 1848. California directly became a state, it was never required to spend a period of time as a territory.
