Columbus Day was first established as a federal holiday in the United States in 1971, observed on the second Monday in October. This holiday commemorates Christopher Columbus's landing in the Americas, a tradition dating back to celebrations as early as 1792. Since then, the date has remained the same, but the holiday's observance and significance have evolved, with many states and cities replacing or supplementing Columbus Day with Indigenous Peoples' Day starting from the 1990s as a response to the historical impacts on Native Americans.
There has been no official change in the date of Columbus Day itself; it remains the second Monday of October since 1971. The main changes have been in how and whether it is observed, with some localities renaming it to highlight Indigenous Peoples' history and issues instead of celebrating Columbus.
