Patriots Day is not observed as a public holiday in California. This civic holiday, originating in New England, primarily commemorates the Battles of Lexington and Concord, which marked the beginning of the American Revolutionary War on April 19, 1775.
Unlike Massachusetts and Maine, where it is a legally recognized state holiday celebrated on the third Monday of April, California does not designate Patriots Day as a public holiday. Its observance is localized to a few specific states, and it is not recognized as a federal holiday across the United States, meaning federal offices and banks nationwide do not close for this occasion. The historical significance of the date is therefore acknowledged differently across various jurisdictions.
Consequently, for residents and businesses in California, Patriots Day is a regular business day, without any statewide closures of government offices, schools, or financial institutions. While the historical events it commemorates are part of national history, the official observance and public holiday status remain jurisdiction-specific to certain New England states, rather than being a national or Californian observance.
