California Admission Day

California Admission Day is celebrated annually on September 9. In 2026, this date falls on a Wednesday. This state holiday commemorates the day California officially became the 31st state of the United States in 1850, marking a pivotal moment in American expansion and the state's rich cultural heritage.

History of California Admission Day

The path to statehood began with the Mexican-American War, which started in May 1846. Following the war, the Treaty of Guadalupe Hidalgo was signed in 1848, ceding a vast portion of Mexico's northern territory—including present-day California—to the United States. At the time, California's population was sparse and did not meet the 60,000-inhabitant benchmark typically required for a territory to achieve statehood. Despite this, the discovery of gold in 1848 spurred a massive influx of settlers, and by 1849, Californians were demanding statehood. Leaders from across the region drafted California's first constitution, which was approved on November 13, 1849, by a vote of 12,064 to 811.

On September 9, 1850, as part of the Compromise of 1850, California was admitted to the Union as the 31st state. It became one of the few states to achieve statehood without first being an organized territory. The day has been observed particularly in the Sonoma area since 1850. In 1924, California's "Bear Flag" flew over the White House to honor the date. In 1984, Governor George Deukmejian signed legislation changing its observance to a personal option, though governors have continued to make public proclamations inviting residents to observe the day.

Why is California Admission Day important?

California Admission Day celebrates the state's cultural diversity, historical significance, and contributions to the nation. California embodies the spirit of innovation and progress as a state with a rich mix of cultures and a history tied to its indigenous roots and its role in U.S. expansion. The day serves as a reminder of the long struggle for California's recognition as a sovereign state and its unique path to statehood.

This observance highlights California's role as a leader in many areas. The state has been at the forefront of social progress, granting women the right to vote in 1911, nine years before the 19th Amendment. California also became the first state with a non-white majority, illustrating its diverse cultural heritage. The day encourages reflection on the state's contributions to the nation's economy, technology, and culture.
