Labor Day vs May Day on September 1: Why Does US Celebrate Worker's Day in September? Key Differences Explained

Labor Day commemorates historic worker protests, including the 1886 Haymarket Massacre, and the ongoing fight for improved working conditions and labor rights in the U.S.

  • On Monday, the United States will observe Labor Day on September 1 as one of eleven federal holidays, reflecting its unique choice to celebrate in September rather than May.
  • Congress in 1894 chose September to establish Labor Day, passing 1894 legislation to move away from the international May 1 demonstrations set by the Second International.
  • The Haymarket events stemmed from a massive 1886 strike involving over 350,000 workers, with authorities breaking the unrest and killing 12 strikers amid demands for safer conditions.
  • The holiday recognizes concrete gains like the one workday, honoring the labor movement's origins and workers' achievements won through strikes and protests.
  • American workers still take to the streets on the first Monday in September, and at the federal level there was little interest in the U.S. to follow the Second International's May 1 program.
