In the United States, which weekday determines the date of the federal Labor Day holiday each year?

In the United States, the federal Labor Day holiday falls on the first Monday in September each year.

The date was fixed by federal law in 1968, when Congress amended the Uniform Monday Holiday Act to move several holidays to Mondays. Labor Day had already been a federal holiday since 1894, but the change created a predictable long weekend.

The holiday honors American workers and the contributions of the labor movement. It is often treated as the unofficial end of summer, although the astronomical season continues until September’s equinox.

Labor Day is sometimes confused with May 1, or International Workers’ Day, which is observed in many countries. They share labor-movement themes but are separate holidays with different histories and dates.
