The state of Rhode Island does not officially recognize or observe Patriots' Day as a public holiday. This observance, which commemorates the anniversary of the Battles of Lexington and Concord, is a legal holiday in the neighboring states of Massachusetts and Maine, where it is held on the third Monday in April.
Instead of Patriots' Day, Rhode Island has its own distinct holiday celebrating its role in the American Revolution. The state observes Rhode Island Independence Day annually on May 4th. This date commemorates the day in 1776 when the Colony of Rhode Island and Providence Plantations became the first of the Thirteen Colonies to formally renounce its allegiance to King George III of Great Britain.
Therefore, for official purposes such as state office and school closures, there is no observance on the third Monday of April. The relevant state-specific historical holiday is Rhode Island Independence Day on May 4th, though it is often observed with local ceremonies rather than widespread business closures.
