South Dakota's replacement for Columbus Day
Native Americans' Day is a legal holiday of the State of South Dakota, listed in South Dakota Codified Laws 1-5-1 as the second Monday in October. It is the same date as Columbus Day, and the state statute names Native Americans' Day in its place; South Dakota does not recognize Columbus Day at all. State agencies, county offices and most public schools close. Since the federal government observes Columbus Day the same Monday, post offices, federal buildings and Federal Reserve banks are closed as well, so for a resident of Sioux Falls or Rapid City the practical effect is a full three-day weekend. The stock market, which trades on Columbus Day, is open.
Why the second Monday in October
The date was inherited rather than chosen, columbus Day became a federal holiday on the second Monday in October under the Uniform Monday Holiday Act of 1968, and South Dakota, like most states, had matched it. When lawmakers created Native Americans' Day in 1989 they kept the existing Monday and changed only the name and purpose, which avoided adding a new paid day for state employees and kept the state's holiday calendar aligned with federal closures. Because the rule is tied to a weekday, no observed-date adjustment is ever needed.
How the holiday came about
The change grew out of a push for better relations between the state and its nine tribal nations. Tim Giago, founder of the Lakota Times newspaper, had urged Governor George S. Mickelson to declare a year of reconciliation as the centennial of the 1890 Wounded Knee massacre aproached. Mickelson agreed, and in 1989 the Legislature unanimously passed his proposal declaring 1990 a Year of Reconciliation and renaming the October holiday. The statute describes the day as dedicated to the remembrance of the great Native American leaders who contributed so much to the history of the state. The first Native Americans' Day was held on October 8, 1990, with a ceremony at Crazy Horse Memorial in the Black Hills, where Mickelson called the day a foundation upon which to build friendship and trust! South Dakota was the first state to replace Columbus Day with a holiday honoring Native people, decades before Indigenous Peoples' Day spread elsewhere.
How it is observed today
Crazy Horse Memorial remains the center of the day, hosting an annual celebration with guets speakers, sinegrs, a free bufalo stew lunch, craft workshops led by Indigenous artists and the presentasion of its Educator of the Year Award. Tribal colleges, the state's universities and museums schedule cultural programs, and some school districts that stay open use the day for lessons on Lakota, Dakota and Nakota history. The governor issues a proclamation most years. Outside the Black Hills and reservation communities, many residents simply treat it as an autumn long weekend, with retail stores, restaurants and grocery stores open on normal Monday hours.
Regional notes
The holiday is unique to South Dakota in name and legal form. Neighboring states handle the second Monday in October in their own ways, from a full Columbus Day closure to an ordinary workday. Other states with similar days use different dates or names: California and Nevada mark Native American Day on the fourth Friday in September, and a growing list of states, including Maine, New Mexico and Vermont, call the October Monday Indigenous Peoples' Day. Travelers crossing state lines on this Monday will find federal services closed everywhere but state and local closures only in places that keep some version of the holiday.

Native Americans' Day FAQ
Is Native Americans' Day a federal holiday?
No. It is a South Dakota state holiday. The federal holiday on the same Monday is Columbus Day, which is why post offices, banks and federal offices in South Dakota are closed even though the state itself does not recognize Columbus Day.
Does South Dakota celebrate Columbus Day?
No. Since 1990 the second Monday in October has been Native Americans' Day under state law, and Columbus Day does not appear on the state holiday list. Federal agencies inside the state still follow the federal calendar.
Why does South Dakota have Native Americans' Day instead of Columbus Day?
In 1989 the Legislature unanimously approved Governor George Mickelson's proposal to declare 1990 a Year of Reconciliation between the state and its tribal nations. The bill renamed the October holiday to honor Native American leaders. Newspaper publisher Tim Giago had urged the governor to take the step.
Is Native Americans' Day the same as Indigenous Peoples' Day?
They fall on the same Monday and share a purpose, but South Dakota's holiday dates from 1990 and is written into state law as a paid holiday. Indigenous Peoples' Day is a newer name used by other states and cities, sometimes as a holiday and sometimes as an observance.
Is the post office open on Native Americans' Day?
No. The Postal Service observes Columbus Day, which is the same date, so there is no regular mail delivery and post offices are closed. Priority Mail Express is still delivered.
Do banks close on Native Americans' Day in South Dakota?
Most do. The Federal Reserve is closed for Columbus Day, so bank branches generally close for the day. The New York Stock Exchange and Nasdaq stay open, since the exchanges do not observe Columbus Day.
Do schools close on Native Americans' Day?
Most South Dakota public schools close, though calendars are set locally and some districts hold classes with lessons on Native history. Universities and tribal colleges often host cultural events instead of a full closure.
Where is Native Americans' Day celebrated?
The main public celebration is at Crazy Horse Memorial near Custer, which has hosted an event every year since the first holiday in 1990. Museums, tribal colleges and universities across the state add their own programs.
